Draw a neat labelled diagram of chloroplast.

A chloroplast is a double-membrane bound organelle found in the cells of green plants and is the site of photosynthesis.

Neat labelled diagram of chloroplast:

Unfortunately I cannot draw images directly here, but the labelled parts to include are:

• Outer membrane
• Inner membrane
• Intermembrane space
• Stroma (fluid matrix inside inner membrane)
• Thylakoid membranes (stacked into grana)
• Granum (stack of thylakoids)
• Lamella (connecting stroma thylakoids)
• Starch grain (stored starch inside stroma)
• DNA and ribosomes inside stroma

Explanation:

• The outer and inner membranes enclose the chloroplast and maintain its shape and selective permeability.
• The stroma is a dense fluid where the Calvin cycle (dark reactions) of photosynthesis takes place, synthesizing glucose.
• Inside the stroma, there are thylakoids, membrane-bound sacs containing chlorophyll pigments essential for light reactions.
• Grana are stacks of thylakoids which increase the surface area for light absorption and house the photosystems I and II.
• Lamellae connect the grana, enabling efficient transfer of molecules and electrons.
• Chloroplasts have their own DNA and ribosomes, allowing them to produce some proteins autonomously.
• Chloroplasts convert light energy into chemical energy via photosynthesis, producing oxygen and carbohydrates from carbon dioxide and water.
