Photosynthesis

The process by which green plants make their food

• autotrophic nutrition

• photosynthesis

• transpiration

• nutrition

The raw materials required for photosynthesis are

• carbon dioxide, chlorophyll and water

• sunlight and chlorophyll and water

• chlorophyll, oxygen, and water

• carbon di oxide, water, sunlight and chlorophyll

The energy conversion takes place during photosynthesis is

• light energy to heat energy

• light energy to chemical energy

• chemical energy to light energy

• light energy to electrical energy

The first event in photosynthesis is

• Absorption of light energy by chlorophyll

• Conversion of light energy into chemical energy

• splitting of water into hydrogen and oxygen

• release of Oxygen

The site of photosynthesis is

• chlorophyll

• chloroplast

• mitochondria

• cell

The oxygen released during photosynthesis come from.........

• water

• carbon dioxide

• chlorophyll

• glucose

Plants take the water required for photosynthesis through the..................

• stomata in their leaves

• root hairs and is transported to leaves through the xylem tissue

• through the chloroplast present in the leaves

• root hairs and is transported to leaves through the phloem

The product of photosynthesis is ........................and the byproduct is.....................

• Glucose, Oxygen

• Oxygen, glucose

• Glucose, CO₂

• CO₂&H₂O

The Oxygen liberated during photosynthesis is given out through the...................

• stomata

• chlorophyll

• root hairs

• xylem

Plants take in CO₂ through ..................

• Root hairs

• Chlorophyll

• Stomata

• Chloroplast
