Question

Green plants and algae make their own food through

photosynthesis. What is photosynthesis?

a cell process that uses energy from sunlight to convert water and glucose into food

a cell process that uses energy from sunlight to convert water and carbon dioxide into food

Oa cell process that uses energy from sunlight to convert
water and oxygen into food

a cell process that uses energy from sunlight to convert water and chlorophyll into food

Answer 1

a cell process that uses energy from sunlight to convert water and glucose into food

Step-by-step explanation:

This is because the plant uses the products from respiration (water and glucose) and sunlight to make food. Plants are the only living organisms (apart from bacteria) that make their own food

Ur welcome

Answer 2

a cell process that uses energy from sunlight to convert water and carbon dioxide into food

Step-by-step explanation:

During photosynthesis, the cell traps light energy to fuel to conversion of carbon dioxide and water into glucose.

A green pigment called chlorophyll traps the light energy to drive the reactions required to synthesise glucose. Only algae and green plants have chlorophyll, so only these organisms perform photosynthesis.

These reactions make glucose, which is a food source, and release oxygen into the atmosphere.
