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

What is is the purpose of chloroplast?
Chloroplasts are membrane bound organelles in plant cells that contain chlorophyll, which absorbs red light and uses it to hydrolyse water to oxygen gas and hydrogen ions. These hydrogen ions pass through the electron transport chain, which is a sequence of membrane proteins which use the energy of the ions to produce ATP (adenosine triphosphate, the molecule used as a short-term energy store in all living cells). The oxygen is used in respiration or diffuses into the surroundings.
The hydrogen ions are transferred by a carrier molecule known as NADP to the calvin cycle, the reaction that makes glucose (sugar) out of carbon dioxide.
These two reactions collectively are the process that absorbs energy from sunlight known as photosynthesis.

Why don't heterotrophs have chloroplast?
Chloroplasts are for autotrophs. Hetrotrophs get C from others.chloroplasts capture light energy.Heterotrophs get energy from chemicals mainly
What are the stack of membranes inside the chloroplast?
Membranes are called thylakoid membranes.Stacks are called granna
Neurones are never in plants.It is a cell in animals.
Where does glucose go after its made by the chloroplast?
They are stored in starch granules.Later transported to various parts as Sucrose.
How is chloroplast and diffusion related?
c02 is diffused into the epidermis of a leaf and the chloroplast uses these molecule along with sunlight to make sugar and oxygen.
Does oscillatoria contains chloroplast?
Yes, Oscillatoria contains chloroplasts. Chloroplasts are responsible for photosynthesis, the process by which plants and algae convert sunlight into energy. In Oscillatoria, chloroplasts use this energy to produce glucose for the organism's survival.
What are the most important chloroplasts pigments?
Chlorophyll a is very important.They are in every photosynthetic cell.
What are stacks of thylokoids in a chloroplast?
They are called grana.They contain photosynthetic pigments.
Why are chloroplasts found in an orchid's root cell?
Orchids do not grow in soil- their roots are frequently in the air, attaching them to other things. Where most plant roots are hidden from light, orchid roots are exposed to the light.
How do chloroplast and mitochondria make energy?
Both of them are not making. Energy is a constant thing.
Where is chlorophyll most abundant in a plant?
Mainly in leave cells. They are modified for photosynthesis
Explain how plant cells get energy by using the words chloroplast sunlight food and sugar?
The main role of chloroplasts is to conduct photosynthesis which takes place inside plant cells where they are based
How do you chloroplasts get energy from sunlight?
They have photosynthetic pigments.They absorb energy of sunlight.
Which part of a green plant shows the greatest increase in chloroplasts by the ending of spring?
Leaf.
Why is chloroplast not needed in animal cells?
Animals are heterophic organisms.They obtain carbon from other organisms.
Do animals have a chloroplasts?
No, animals do not have chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy. Animals obtain energy by consuming other organisms or plants, rather than through photosynthesis.
What of most plants appear green because they contain chlorophyll?
The leaves of most plants appear green because they contain chlorophyll.
What foods have cell walls and chloroplasts?
Plant foods have them.Green parts from plants have both.
Why chloroplast is said to be cell within a cell?
A Chloroplast is sometimes refered to as a "cell within a cell" due to the fact it has its own membrane is separated from the rest of the cell. This may also be due to having small organelles within the Chloroplast.
