Do all plant cells have chloroplasts why or why not?

No, not all plant cells have chloroplasts. Chloroplasts are only present in specialized plant cells called mesophyll cells, which are responsible for photosynthesis. Other types of plant cells, such as root cells or stem cells, do not typically contain chloroplasts.

What is the major function of the choloroplasts?

The major function of chloroplasts is to conduct photosynthesis, which is the process by which plants convert sunlight into energy-rich molecules to fuel their growth and development. During photosynthesis, chloroplasts use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Name of process completed by the mitochondria and chloroplast?

The process completed by mitochondria is cellular respiration, which generates ATP for energy. The process completed by chloroplasts is photosynthesis, which converts light energy into chemical energy in the form of glucose.

What part of the electromagnetic spectrum do the chloroplasts use?

Chloroplasts primarily utilize the visible light spectrum for photosynthesis, specifically blue and red wavelengths. These wavelengths are absorbed by pigments such as chlorophyll, which converts light energy into chemical energy used for photosynthesis.

Photosynthesis occurs in chloroplast while cellular respiration occurs in a.chloroplasts b.nuclei c.mitochondria d.cytoplasm?

c. mitochondria. Cellular respiration takes place in the mitochondria of the cell, where glucose is broken down to produce ATP, the cell's main energy source. It is distinct from photosynthesis, which occurs in the chloroplasts and involves the conversion of light energy into chemical energy in the form of glucose.

Why is there no chloroplast in the onion bulb?

Chloroplast is found in parts of plants exposed to sunlight, where it is used in photosynthesis. Onion bulbs are not normally exposed to sunlight, so there is no need for chloroplasts in the bulb.

What would happen if a plant cell has very few chloroplasts?

If a plant cell has very few chloroplasts, it would have reduced ability to carry out photosynthesis efficiently. This would result in lower levels of glucose production, affecting the plant's growth and overall health. Additionally, the plant may appear pale or yellowish due to decreased chlorophyll production.

Do all protists contain chloroplasts?

No, not all protists contain chloroplasts. Some protists, such as algae, have chloroplasts for photosynthesis, while others do not and obtain nutrients through other means like ingestion or absorption.

What everyday object can be compared to chloroplasts?

Solar panels can be compared to chloroplasts because they both capture energy from the sun and convert it into usable forms – chloroplasts convert sunlight into glucose through photosynthesis for the plant, while solar panels convert sunlight into electricity for human use.

Are chloroplasts and plant cells part of a symbiotic relationship?

Yes, chloroplasts and plant cells have a symbiotic relationship. Chloroplasts are organelles within plant cells that perform photosynthesis to produce food for the cell. This relationship originated from a symbiotic event where a photosynthetic bacterium was engulfed by a eukaryotic cell, leading to the evolution of the chloroplast.

Does a flower have chloroplasts?

The tortoise (GUI)is one of the four spiritually-endowed creatures (Figure 1) described in the Book of Rites of the Confucian Classics, where it serves as an emblem of strength, longevity, and endurance, and symbolizes the Universe (1). Each of these creatures is associated with a direction and element, the tortoise, usually depicted in conjunction with a snake (Figure 2), represents the north, and is thereby associated with the water, darkness (the color black), and the earth (28), the element which was later put into the five element system in the center.The tortoise shell was long used in divination, by observing the patterns of cracks that developed when a hot instrument was touched to one of its many "divination points," and then interpreting the implication of the pattern. The prognostications and insights learned from the cracks were often written right onto the shells, and it is from buried fragments of tortoise shells (along with some mammal bones that were used similarly) that we know the most ancient forms of Chinese writing (2; Figure 3). The Chinese character bu (Figure 4), which means to divine by looking at the cracks in the tortoise shell as the heat develops them, is represented by two lines depicting cracks. This character became incorporated into numerous others as a radical. Thus, the tortoise and its shell have been an important part of Chinese culture.Further, the tortoise has been used as both food and medicine since ancient times, and is recorded as being used for these purposes since the Han Dynasty, 2000 years ago. Regarding their inclusion in the Chinese diet, E. N. Anderson comments that "Animals that are very tenacious of life, or very unusual-looking and -acting, are regarded as having special power; they are supplementing (bu). Notable supplementing foods are pangolin, raccoon dogs, soft-shelled turtles, tortoises, snake head fish, birds of prey....(3)" Although the tortoise is not a major food in China today (turtles have long been preferred over tortoises for food), it remains one of the foods included in some diets. Anderson also points out that "During Han, and throughout Chinese history, the boundary between medicine and food was so vague as to be non-existent in practice. Many things were purely medicines, but medicines often became foods if people learned to like them; many foods became merely medicines when people stopped relishing them...."

What are chloroplasts responsible for?

Chloroplasts are responsible for photosynthesis, the process by which plants and algae convert sunlight into energy in the form of glucose. They contain chlorophyll, a pigment that captures sunlight and uses it to produce food for the plant. Chloroplasts are what give plants their green color.

A cell with chloroplasts is probably specialized for what?

A cell with chloroplasts is likely specialized for photosynthesis, as chloroplasts are responsible for converting light energy into sugar through the process of photosynthesis. This type of cell would typically be found in plant cells or some protists.

How do chloroplasts turn sun energy into sugar?

Chloroplasts use a process called photosynthesis to convert sunlight into sugar. This process involves capturing sunlight with pigments like chlorophyll, using the energy to split water molecules, and then combining the hydrogen from water with carbon dioxide to produce sugar molecules. These sugar molecules are then used as energy sources for the plant.

What would happen if an animal cell contained chloroplasts?

If chloroplast invaded an animal's cells the animal wouldn't need to eat because chloroplast is were photosynthesis takes place and photosynthesis makes food for the animal. Photosynthesis would also make oxygen for the animal so it wouldn't half to breath. Also, if chloroplast invaded the animal's cells they would probably turn green from the chlorophyll inside the chloroplast.

Where do scientists believe mitochondria and chloroplasts originated?

Some scientists believe that mitochondria and chloroplasts were at one time independent-living bacteria that were engulfed by eukaryotic cells, forming an endosymbiotic relationship. This is because both mitochondria and chloroplasts have their own DNA and replicate themselves within the cells in which they occur.

Which compartment in chloroplasts is likely to have the lowest pH?

The thylakoid lumen is likely to have the lowest pH in chloroplasts due to the accumulation of protons during the light-dependent reactions of photosynthesis.

What are raw materials needed for photosynthesis and what are their products?

the chemical equation for photosynthesis is:

water + carbon dioxide + sunlight = oxygen + glucose

so the first three are the requirments and the last two are the final product of the process

What can chloroplast be compared to?

Chloroplasts can be compared to solar panels as they both capture sunlight and convert it into energy (photosynthesis in chloroplasts, electricity in solar panels).

What diseases are associated with chloroplasts?

Chloroplasts are not associated with diseases. They are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts are crucial for the survival of plants and are not linked to any diseases.

What are the disk shaped sacs suspended in the stroma?

The disk-shaped sacs suspended in the stroma are called thylakoids. They contain the chlorophyll pigment and are the sites where light-dependent reactions of photosynthesis take place. Thylakoids are interconnected to form grana, which are stacks of thylakoids found in chloroplasts.

What is the chloroplast and why dont cells have chloroplast?

Only photosynthetic organisms (organisms that perform photosynthesis), such as plants, some bacteria, and some protistans, have chloroplasts. Animal cells do not have chloroplasts because they do not carry out photosynthesis.

What does chloroplast do in a plant cell do?

It captures the energy from sunlight as chemical energy.

Where in the chloroplast is the H plus concentration highest?

The chloroplast is the hydrogen ion concentration is highest in the spaces of its thylakoid membrane. The ions get pushed into these spaces during the transportation of electrons.

Cooperation of the two photosystems of the chloroplast is required for?

The cooperation of the two photosystems of the chloroplast is required for the efficient generation of ATP and reducing power (NADPH) during photosynthesis. Photosystem II captures light energy to drive the electron transport chain, while photosystem I helps in the production of NADPH by receiving electrons from photosystem II. This cooperation is essential for the overall functioning of the light-dependent reactions in the chloroplast.
