Chloroplasts are a part of a plant's cell. They capture energy from light.

1,379 Questions

What are light absorbing substances in chloroplasts called?

Light-absorbing substances in chloroplasts are called pigments. The main pigment responsible for absorbing light energy for photosynthesis is chlorophyll.

What does the single chloroplast look like?

Chloroplasts are green,round,small, and have two membranes

Is chloroplast both eukaryotic and autotrophic?

The chloroplast is the organelle that enables photosynthesis. So, a cell with a chloroplast will be autotrophic, but not the chloroplast itself. A eukaryote is a type of cell with a nuclues, and other membrane bound organelles. So chloroplasts, eukaryotes, and autotrophs can't be related the way you asked in your question. I hope that helps!

Do chloroplasts convert sunlight into energy?

Yes, chloroplasts convert sunlight into energy through the process of photosynthesis. Light energy is absorbed by chlorophyll molecules in the chloroplasts, which then convert this energy into chemical energy in the form of glucose.

What chemical is not found in chloroplast?

A chemical that is not found in chloroplasts is hemoglobin, which is a protein found in red blood cells that is responsible for transporting oxygen in the bloodstream. Chloroplasts primarily contain chemicals involved in photosynthesis, such as chlorophyll and various enzymes.

Dehydration reactions involve the removal of what molecule?

Dehydration reactions involve the removal of a water molecule from two adjacent molecules. This process forms a covalent bond between the molecules, typically resulting in the formation of a larger molecule.

Is bacteria in Chloroplast?

Bacteria are Monera. Chloroplasts belong to Protista. Bacteria Do not have chloroplast which prepare food and are parasites while chloroplasts have chloroplast and prepare their own food. Diatoms are chloroplasts

If you grind up the chloroplasts found in spinach leaves into a liquid solution would the solution have a green color?

Yes, grinding up chloroplasts found in spinach leaves into a liquid solution would result in a green-colored solution. This is because chloroplasts contain the green pigment chlorophyll, which gives plants their green color.

Compare and contrast chlorophyll and chloroplast?

Chlorophyll is a light sensitive protein complex (with pigments associated) that is found inside chloroplasts.

Chloroplasts are for making the plant's food. The chlorophyll are found inside the chloroplasts. It absorbs light for photosynthesis. The chlorophyll absorbs the least green light, and this is reflected out, making the chlorophyll, chloroplasts, cells, and plants look green. The chloroplasts use all the energy from the chlorophyll to make the plant food.

The flat discs found in chloroplasts are called?

The flat discs found in chloroplasts are called thylakoids. Thylakoids are membrane-bound compartments that contain chlorophyll and other pigments, where photosynthesis takes place. Multiple thylakoids stack on top of one another to form grana.

Do mitochondria and chloroplasts include compartments where hydrogen ions are connected?

Yes, both mitochondria and chloroplasts have compartments where hydrogen ions are actively pumped across a membrane to create a proton gradient. In mitochondria, this occurs in the inner mitochondrial membrane, while in chloroplasts, it happens across the thylakoid membrane. The proton gradient generated is used to drive ATP production through oxidative phosphorylation in mitochondria and photosynthesis in chloroplasts.

If you looked under a microscope and saw a cell with a cell wall and chloroplasts you would know that the cell is?

A plant cell. The presence of a cell wall and chloroplasts is a characteristic feature of plant cells. Cell walls provide structural support while chloroplasts are responsible for photosynthesis.

Why are mitochondria and chloroplast considered cells or bacteria?

I'm not sure about chloroplasts, but with mitochondria evolutionary history has led biolgists to believe that the mitochondria now present in eukaryotic cells to have originated a couple billion years ago when a very basic eukaryotic cell injested (ate) a bacterial cell. Then, instead of digesting it for food, the bacterial cell just stayed inside and functioned with the eukaryotic cell. The evidence for this lies in the structure, genetic information (mitochondria have their own DNA and replicate separately) and proteins present. This is why it could be considered a cell (bacterial), because it, at one point in history, was an actual bacterial cell.

i think the above answer is a little misleading to the question. so my answer is mitochondria and chloroplast are not considered cells or bacteria. bacteria is a cell and mitochondria and chloroplasts can be found in cells (plant and animal cells, not bacteria cells).

What organelle not in animals may contain chloroplasts?

Plant cells contain chloroplasts, which are membrane-bound organelles that carry out photosynthesis. This organelle is not found in animal cells.

Why is the primary pigment found in chlorophyll?

The primary pigment found in chlorophyll is chlorophyll itself, specifically chlorophyll a. It is responsible for capturing light energy during photosynthesis in plants. Chlorophyll absorbs mostly blue and red wavelengths of light, reflecting green light, making plants appear green.

Where do chloroplast capture energy to make food from?

The process of photosynthesis requires carbon dioxide, energy and light.

The function of the chloroplast is to capture energy from light in order to photosynthesis (make food using light).

Inside a chlorplast are hundreds of light absorbing "buckets" called photsystems which capture and absorb light energy. The energy from the light colletively creates energy which goes on to be used in the stages of photsynthesis.

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.
