Question

Explain chloroplast?

Answer 1

Chloroplasts...======>>>>>>>
It  is a large, complex double membraned organelle that performs the function of photosynthesis within plant cells and contains the substance chlorophyll...
The chloroplasts use photosynthetic chlorophyll pigment and take in sunlight, water and carbon dioxide to produce glucose and oxygen.
An important structure in the chloroplasts is the inter-connected, flattened, membranous sacs called thylakoids.
These  are the site of the photosynthetic light reactions and it involves the transfer of electrons.
 The chloroplasts have their own DNA and ribosomes.

Answer 2

These are the green pigmented plastics found mostly in green plants.

Special Points:-

=>The space between the inner Membrane of the chloroplast is called the stroma.

=>Organised flattened sacs are present in the stroma called the thylakoids.

=>Thylakoids are further arranged in stacks called the Grana.

=>These chloroplast traps the solar energy and prepares food for the plant thus plays an important role in photosynthesis.

=>These contain essential enzymes within it that helps in the synthesis of carbohydrates and proteins.
