Compare the functions of mitochondria and chloroplasts in cells?

Mitochondria are responsible for cellular respiration, converting glucose into ATP for energy. Chloroplasts, on the other hand, carry out photosynthesis, converting sunlight, water, and carbon dioxide into glucose and oxygen. Both organelles have double membranes and their own DNA.

What is the synonym and antonym for chloroplast?

A chloroplast is an organelle found in many plants that contains the mechanisms for photosynthesis, the process by which plants obtain energy from sunlight. It has no sysnonym and antonym since it is an object, not a description.

Do the cells of the onion bulb possess chloroplasts?

Onions are the root bulbs of onion plants. The plant itself contains chloroplasts, which cause the green colour, whereas the onion bulb itself contains other pigments and few, if any, chloroplasts.

What is the purpose of using sucrose solution when germinating pollen grains?

Using a sucrose solution in germinating pollen grains provides a readily available energy source for the pollen grains as they begin to germinate. This helps to support metabolic processes and allows the pollen grains to grow a pollen tube, which is necessary for fertilization to occur.

What substance inside the chloroplast makes it green?

Chlorophyll is the pigment inside the chloroplast that gives it a green color. It absorbs light energy to drive the process of photosynthesis, where plants convert light energy into chemical energy.

How do you call the sack-like structure in the chloroplast?

The sack-like structure in a chloroplast is called a thylakoid. Thylakoids are membrane-bound compartments where the light-dependent reactions of photosynthesis occur. They are stacked on top of each other to form grana.

What are chloroplast in plants?

Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process through which plants convert sunlight into energy. They contain chlorophyll, a green pigment that captures sunlight and uses it to produce sugars and oxygen. Chloroplasts also play a role in storing energy in the form of carbohydrates for the plant's growth and development.

Why do plant cell need chloroplasts?

Plant cells need chloroplasts because they are the organelles responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll, a pigment that captures light energy and uses it to produce glucose, which the plant can use for energy. Without chloroplasts, plants would not be able to make their own food and would not survive.

Compare the functions of chloroplasts and mitochondria?

Mitochondria is where cellular respiration takes place and where most energy in the form of ATP is generated. Chloroplasts convert sunlight energy into chemical energy stored in sugar molecules. Mitochondria uses chemical energy; chloroplasts use light energy.

How can you use chloroplast in sentence?

Chloroplasts are the organelles in plant cells where photosynthesis takes place, converting sunlight into energy. The chloroplasts in the leaf cells contain chlorophyll, a pigment that gives plants their green color and helps absorb sunlight. Without chloroplasts, plants would not be able to produce their own food through photosynthesis.

What is a poem for chloroplast?

What process takes place in the chloroplasts of plant cells?

Photosynthesis takes place in the chloroplasts of plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen. This process involves two main stages: light-dependent reactions that occur in the thylakoid membrane, and light-independent reactions (Calvin cycle) that take place in the stroma.

A filamentous organism has been isolated from decomposing organic matter This organism has a cell wall but no chloroplasts How would you classify this organism?

Based on the description provided, the filamentous organism can be classified as a fungus. Fungi are filamentous organisms that have a cell wall but lack chloroplasts. They play a crucial role in the decomposition of organic matter in various environments.

Why mitochondria and chloroplasts are reffered to as cell encaptured bacterium?

because duffers it originated as a cell encaptured bacterium and because the MRNA content in mito and chloroplasts is aruond 1 to 3 % therefore they cant synthesise some of their proteins so they are refferd as semi autonomous and if they could make all of their required proteins they would be called as fully autonomous or simply autonomous

In which part of the chloroplast do the following major stages of photosynthesis occur of trapping of light?

The trapping of light in photosynthesis occurs in the thylakoid membrane of the chloroplast, specifically in the photosystems located within the thylakoid membrane. This is where the process of light absorption by chlorophyll and the conversion of light energy into chemical energy take place.

The enzyme-rich solution found within the chloroplast is called the?

The enzyme-rich solution found within the chloroplast is called the stroma. It contains enzymes essential for the process of photosynthesis, allowing the chloroplast to carry out its function of capturing light energy and converting it into chemical energy.

What are examples of chloroplast?

Chloroplasts are an example of an organelle. Organelles are specialised subunits found in cells. Other examples of organelles are; mitochondria, endoplasmic reticulum and Golgi apparatus.

Are chloroplasts present in parenchyma cells?

No.

This is because consumers do not synthesize organic compounds from inorganic compounds such as carbon dioxide and water. Producers do that.

Chloroplasts are involved in photosynthesis, which is one process by which glucose may be synthesized from carbon dioxide and water. All chloroplasts are found in producers.

What is stroma in chloroplast?

The stroma is the fluid-filled space inside the chloroplast that surrounds the thylakoid membranes. It contains enzymes responsible for the Calvin cycle, where carbon dioxide is fixed and converted into sugars. The stroma also plays a role in various metabolic pathways within the chloroplast.

Where are chlorophyll a chlorophyll b and the carotenoids are located?

Chlorophyll a, chlorophyll b, and carotenoids are located in the thylakoid membranes of chloroplasts. They are essential pigments used in the process of photosynthesis to capture light energy and convert it into chemical energy.

Why are no chloroplasts present in these pollen grains?

Pollen grains do not contain chloroplasts because they are not involved in photosynthesis. Instead, pollen grains contain other organelles such as mitochondria to provide energy for pollen germination and growth once it reaches the female reproductive organ of the plant. Chloroplasts are primarily found in the leaves of plants where photosynthesis occurs.

What layer in a leaf contains the most chloroplasts?

The palisade layer of the leaf contains the most chloroplasts. This layer is positioned right below the upper epidermis and is responsible for the majority of photosynthesis due to its high concentration of chloroplasts.

What is the name of the process that occurs inside the chloroplasts?

The process that occurs inside the chloroplasts is called photosynthesis. This process involves converting light energy into chemical energy by utilizing water and carbon dioxide to produce glucose and oxygen.

Does chloroplast have cristae?

Chloroplast does not have cristae but mitochondria does. Instead, chloroplast's inner membrane have thylakoids, which are flattened sacs. Thylakoids at times form grana, which are disk stacks.

A gelatinous matrix inside the chloroplast containing ribosomes DNA and enzymes called?

The gelatinous matrix inside the chloroplast containing ribosomes, DNA, and enzymes is called the stroma.
