Question

The cell organelle where photosynthesis occurs

Answer 1

Hint: The organelle where photosynthesis takes place is an oval-shaped organelle which is also a double membrane organelle with a space between two membranes which is known as intermembrane space.

Complete answer:
1.Different organelles are present in plants for various functions, one such organelle is chloroplast which is responsible for photosynthesis.
2.Chloroplasts are present along the walls of mesophyll cells present in the leaves of plants.
3.Chloroplast contains the chlorophyll pigment that is used to capture sunlight which converts the light energy into glucose which is the main product and oxygen and water are also produced as By-products.
4.Chloroplasts are self-replicating because they have their DNA and it also produces different amino acids and lipids required for the formation of chloroplast membranes.
5.Plant cell contains plastids and chloroplast is also a type of plastid.
6.Chloroplast contains a membranous system that contains grana and stroma lamellae which is also known as the fluid stroma.
7.ATP and NADPH are synthesized in the membranous system of chloroplast through various reactions known as light reactions.
8.The synthesis of sugars take place in stroma lamellae, The reactions occurring at stroma lamellae are known as dark reactions.
9.Chloroplast can be found in green plants and green algae.

Hence, the correct answer is Chloroplasts

Note: Synthesis of Sugar in chloroplast are known as dark reactions only to distinguish them with light reactions, it does not mean that synthesis of sugars takes place in dark conditions. The sugar formed in the dark reaction gets converted to starch.
