Question

What is the most important function of chloroplast?

Answer 1

The photosynthetic pigment chlorophyll is found in chloroplasts, which catches sunlight and transforms it into usable energy, releasing oxygen from water. All green plants and algae include chloroplasts. They are the plants' food makers. These are found in the plant's guard cells, which are found in the leaves. They have a lot of chlorophyll, which helps to trap sunlight. Animal cells do not have this cell organelle. Chloroplast contains its own DNA and is capable of reproducing without the help of the rest of the cell.

Complete answer:
The roles of chloroplasts are as follows:
The chloroplast's primary job is to manufacture food through the photosynthesis process.
Chemical energy is received and transformed from light energy.
Chloroplast contains a component called chlorophyll, which traps sun energy and is used for food synthesis in all green plants.
Photolysis of water yields NADPH and molecular oxygen.
The process of photosynthesis produces ATP (adenosine triphosphate).
During the Calvin Cycle, or nighttime reaction of photosynthesis, carbon dioxide acquired from the air is used to create carbon and sugar.

Note:
All higher plants include chloroplasts. It is an organelle situated within the plant mesophyll cells. The diameter and thickness of the chloroplast are typically $4 - 6{\text{ }}m$ and $1 - 3{\text{ }}m$, respectively. They are a type of double-membrane organelle having outer, inner, and intermembrane space. The grana and stroma are two different areas that exist within a chloroplast.
Grana are built up of thylakoids, which are stacks of disc-shaped structures. The functional units of chloroplasts are the grana, which are made up of chlorophyll pigments.
Stroma is a homogeneous matrix that contains grana and is analogous to the cytoplasm in which all organelles are embedded in cells. Various enzymes, DNA, ribosomes, and other chemicals are also found in Stroma. The role of Stroma lamellae is to connect the stacks of thylakoid sacs.
