Photosynthesis: Chloroplasts

The video explains how photosynthesis occurs in chloroplasts within plant cells. Chloroplasts contain photosynthetic membranes and structures like thylakoids and grana. Chlorophyll and other pigments in thylakoids capture light energy, organized into photosystems. Chloroplasts are crucial for converting sunlight into chemical energy.

What is the primary function of chloroplasts in green plants?

• To store nutrients

• To conduct photosynthesis

• To provide structural support

• To transport water

What are the disk-shaped structures inside chloroplasts called?

• Grana

• Stroma

• Thylakoids

• Photosystems

What is the term for stacks of thylakoids?

• Stroma

• Photosystems

• Grana

• Chlorophyll

Where are chlorophyll and other pigments located within the chloroplast?

• In the nucleus

• In the thylakoids

• In the cell wall

• In the stroma

What is the role of photosystems in chloroplasts?

• To store energy

• To produce oxygen

• To collect light

• To transport water
