Energy is the ability to do work.

Front

Why do living things need energy?

Back

Living things need energy to carry out life processes like breathing, pumping of the heart, and growing.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants make their own food using light energy from the sun, water, and carbon dioxide.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are sugar (glucose) and oxygen.

Front

What do plants use to trap light energy?

Back

Plants use chlorophyll in their leaves to trap light energy.

Front

What happens to extra sugar made by plants?

Back

Extra sugar is stored as starch in plant parts such as leaves, flowers, fruits, roots, or seeds.

Front

How can we test for starch in plants?

Back

We can test for starch using iodine solution, which turns blue-black in the presence of starch.

Front

What are the conditions required for photosynthesis?

Back

The conditions required for photosynthesis are water, carbon dioxide, and light.

Front

What happens to oxygen produced during photosynthesis?

Back

Oxygen is given out into the environment through the plant's stomata.
