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

What is the function of the thylakoid in the chloroplast?
It takes in light energy to make food for plants.
Does vascular plants have a chloroplasts?
yes. chloraplasts is necessary for all plants to receive energy from sun.
What best describe a chloroplast?
A chloroplast is an organelle in the plant cell to help produce energy from photosynthesis.OR a plastid
How is light captured by chloroplasts?
They are flat, oval like shapes spread out to maximize light capture/
Linear arrangement in the columnar palisade cells
Why are chloroplasts important to animals?
Chloroplasts in plants, are part of the vital system of photosynthesis. This allows a plant to convert sunlight into nourishment for the plants, and by extension, nourishment for plant eating animals, who gain nutrients from the plants, and by the carnivores that feed on those plant eating animals. Additionally, being part of the process of photosynthesis, allows the plant to generate breathable oxygen, permitting an ecosystem to exist.
What is the place were the chloroplast is located?
They are in plant cells. Some protists like algae have
Does chloroplast contain stoma?
The chloroplast is a cellular organelle that performs photosynthesis while a stoma (plural: stomata) is a two-celled structure seen on leaf surfaces. Thus, chloroplasts cannote be said to "contain stomata". Stomata are pores that regulate water evaporation and gas exchange. The two guard cells that form the stomatal pore each contain chloroplasts.
However, I feel you may be confusing the term "stoma" with "stroma". "Stroma" is a term used for the liquid matrix seen inside chloroplasts - i.e. chloroplasts contain stroma. Many important photosynthetic reactions occur in the stroma and thylakoids in the chloroplast are surrounded by it.
What color are the regions of visible spectrum in which chlorophyll reflect?
They are the greens. That is why plants are green
Is chloroplasts surrounded by a double membrane?
in animals (including humans), single. its the same for all eukaryotes. same goes for all species of archea except three (making up a unique genus).
some bacteria have a double membrane around their cytoplasm, but not all.
What type of unicellular organism contains chloroplasts?
Chloroplasts are in eukariyotes.Best example is unicellular algae.
What is the functions granum in structure of chloroplast?
The storage granule are membrane bounded vesicles containing condensed secretory materials (often in an inactive, zymogene, form). Otherwise known as zymogene granules or vacuoles. Granules found in plastids or in cytoplasm, assumed to be food reserves, often of glycogen or other carbohydrate polymer.
What are the structures in cells that contain chlorophyll?
Tiny structures in palisade are called granna .
How many chlorophyll pigments present in chloroplast?
Chlorophyll is NOT the only pigment contained in a plant cell because all chlorophyll does is give the plant its green color. so do you think tat the only pigment in plant cells would be hte one that gives the plant its color? I DONT THINK SO. there are many pigments in plant cells
When does carbohydrate production occur in a chloroplast?
During The Calvin Cycle cycle, sugars are produced in the chloroplast.
Where are the pigments located in the chloroplast?
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.
Where in the plant chloroplast does each stage happen?
The light reaction happens in the thylakoid membrane and converts light energy to chemical energy.
The dark reaction takes place in the stroma within the chloroplast, and converts CO2 to sugar.
They are located in the thylakoids, which are in chloroplasts in the mesophyll cells of a leaf.

Chlorophyll is green therefore it is located in the green parts of a plant.
Does elodea cell have chloroplast?
Yes, elodea cells have chloroplasts. Chloroplasts are the organelles responsible for photosynthesis in plant cells, including those of the elodea plant. The green color of elodea leaves is due to the presence of chlorophyll in the chloroplasts.
Cyanobacteria > Red Algae > Green Algae > Land Plants
What is a green pigment found in the chloroplasts of plants called?
They are called the chlorophyll pigments. They are essential for photosynthesis
Which plant cells does not have contain chloroplast?
All the non-green parts of plant does not possess chlorophyll as the green colour of the leaves of plants are due to presence of chlorophyll. These parts do not contain chlorophyll in their cells because they carry other functions like transort of food and water, supprot to the plant etc...
