What pigments are found in chloroplasts?

Chloroplasts contain structures called thylakoids (this is where photosynthesis takes place); inside the thylakoid membrane are colored photosynthetic pigments.

There are a total of 6 photosynthetic pigments, although 2 are by far the most important; these are known as Chlorophyll.

There are two forms of Chlorophyll, Chlorophyll a and Chlorophyll b. Chlorophyll a absorbs light in the 700 mn (nanometer) frequency range and Chlorophyll b in the 680 nm frequency range of the visible light spectrum.

The 6 photosynthetic pigments are:

Chlorophyll a (C55H72MgN4O5) is blue-green in color (reflects this colour)

Chlorophyll b (C55H70MgN4O6) is yellow-green in color

Carotene is orange in color

Xanthophyll is yellow in colour

Phaeophytin a is grey-brown in color

Phaeophytin b is yellow-brown in color

The different locations and concentrations of these pigments give plants their various colors.

The main pigments found In chloroplast is CHLOROPHYLL.

Are membranous sacs and chloroplast the same thing?

No, they are not. "Membranous sac" is a descriptive term that can refer to a number of different structures, whereas a chloroplast is a clearly defined organelle with a clearly defined function (photosynthesis)

There are membranous sacs found inside chloroplasts that are called thylakoids, which form the grana (singular "granum"). The thylakoid membranes contain chlorophyll and other pigments to trap energy from incoming light.

Where would you not find chloroplasts in a plant?

In the roots, and on the underside of the leaf. This is simply because there is no point, as no sun is going to reach those areas.

The main role of the chloroplast is to conduct photosynthesis.

What is the function of the chloroplast?

Chloroplast is the site of photosynthesis. It produces glucose using CO2 and water.It also conuct photorespiration.

What kingdom is chloroplast in?

KINGDOM??!!

Organisms with cells that contain chloroplast are mostly in the plant kingdom, (kingdom plantae). Kingdom refers to the grouping of whole organisms. Chloroplasts are macromolecules in specific organelles capable of transforming carbon dioxide and water into sugar using energy from the sun. Some protista also have chloroplasts in their cells, and some prokaryotic organisms have chlorophyll like pigments which also photosynthesis

What would happen if a plant's chloroplasts were destroyed?

the plant would wither up and die because the plant's chloroplasts are the nutrient makers in a plant

How is chloroplasts compared to a school?

A translator is much like a chloroplast, it listens to one person saying a language (like the suns rays, water, and other nutrients) and turns it into another language (glucose).

What is a chloroplast?

Chloroplast is an organelle found in plants and algae cells where photosynthesis occurs.

The chloroplast contains chlorophyll which is the light sensitive pigment that powers photosynthesis and other pigments. Chlorophyll gives the plant its green color

A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms.

Chloroplasts are what give plants their green color.

Organelle that makes sugars, using carbon dioxide, water, and the energy from sunlight.

Cholorplasts can be found in plant cells and produces food.

It is an eukariyotic organelle. It is important for photosynthesis

What is zone of inhibition?

It is the area on an agar plate where growth of a control organism is prevented by an antibiotic usually placed on the agar surface. If the test organism is susceptable to the antibiotic, it will not grow where the antibioitic is.

Why don't onion cells have chloroplasts?

Chloroplasts contain chlorophyll which help to make the food for the plant (glucose). First, chloroplasts are essential for the process of photosynthesis. You need to know that the onion bulb we refer to in daily life grows underground, which is not exposed to the sunlight, it only stores food for the plant. And you also need to know, the process of photosynthesis, requires lights. Because onion bulbs are underground, what is the use of having chloroplasts? The onion plants have green shoots where there are chloroplasts. You can simply tell that there is no chloroplast in onion bulbs because they are not green. Onion bulbs just basically shares a similar environment with root cells.You can check the images in Google and you actually see that onion cell does not have any chloroplasts.

Why mitochondria and chloroplast are semi autonomous in nature?

because of their own genetic materials like DNA and can prepare their own required protein. DNA can decode into mRNA and mRNA will translated into proteins that is why they are semi autonomous

What is the function of a chlorplast in a leaf?

No it's not kl.... anyways...!!!

**The function of leaves is to absorb sunlight so photosynthesis can occur to make food for the plant.

They also let water, oxygen and carbon dioxide in and out through the stomata**

Yes. This is the part where plants produce their food.

Is there chloroplasts in animal cells?

There is NO chloroplasts in animal cells. There is only in plant cells because chloroplasts give plants there green color.
