Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is the process plants use to turn sunlight into food. They take in sunlight, water, and carbon dioxide to make sugar and oxygen.

Question 2

Why do plants need sunlight?

Accepted Answer

Plants need sunlight to make their own food. The light helps them turn water and air into sugar, which gives them energy to grow.

Question 3

What do plants use water for in photosynthesis?

Accepted Answer

Plants use water from their roots to help make sugar. The water also helps them release oxygen back into the air.

Question 4

What is the role of carbon dioxide in photosynthesis?

Accepted Answer

Plants take in carbon dioxide from the air. They use it to help create sugar, which becomes their food.

Question 5

What part of the plant absorbs sunlight?

Accepted Answer

The leaves are the part of the plant that absorb sunlight. They have a special green pigment called chlorophyll that helps soak up the light.

Question 6

Why are plants green?

Accepted Answer

Plants are green because of a pigment called chlorophyll in their leaves. Chlorophyll absorbs sunlight and makes the leaves look green to us.

Question 7

How do plants get water for photosynthesis?

Accepted Answer

Plants absorb water through their roots from the soil. The water travels up through the stem to the leaves where photosynthesis happens.

Question 8

What is oxygen, and why do plants make it?

Accepted Answer

Oxygen is a gas that plants release during photosynthesis. They make it as a byproduct when they turn sunlight, water, and carbon dioxide into sugar, and we need it to breathe!

Question 9

Can plants photosynthesize without light?

Accepted Answer

No, plants cannot photosynthesize without light. They need sunlight to kick-start the process of making food.

Question 10

Do all plants photosynthesize in the same way?

Accepted Answer

Most plants photosynthesize in a similar way, but some might have differences depending on their environment. However, they all need sunlight, water, and carbon dioxide.

Question 11

What happens to the sugar that plants make?

Accepted Answer

Plants use the sugar they make for energy to grow and to make other parts of the plant, like flowers and seeds. They can also store it for later.

Question 12

Do plants photosynthesize at night?

Accepted Answer

No, plants do not photosynthesize at night because there is no sunlight. They rest and use stored energy at night instead.

Question 13

How does photosynthesis help animals and people?

Accepted Answer

Photosynthesis helps animals and people by providing oxygen to breathe and food to eat. Plants are the start of the food chain for many living things.

Question 14

Why is photosynthesis important for our planet?

Accepted Answer

Photosynthesis is important because it helps clean the air we breathe by turning carbon dioxide into oxygen. It also creates food that supports life on Earth.

Question 15

Do underwater plants photosynthesize?

Accepted Answer

Yes, underwater plants like seaweed and kelp photosynthesize too. They use sunlight that reaches through the water to make their food.

Question 16

What would happen if photosynthesis stopped?

Accepted Answer

If photosynthesis stopped, plants wouldn't be able to make food or produce oxygen, and many living things might not survive. It would disrupt the balance of life on Earth.

Question 17

Do plants need soil for photosynthesis?

Accepted Answer

Plants don't need soil to photosynthesize, but they do need nutrients from the soil to grow well. They mainly need sunlight, water, and carbon dioxide for photosynthesis.

Question 18

What kind of gas do plants take in for photosynthesis?

Accepted Answer

Plants take in carbon dioxide from the air around them. They use it along with water and sunlight to make sugar and oxygen.

Question 19

How do plants help keep the air clean?

Accepted Answer

Plants help keep the air clean by using carbon dioxide and releasing fresh oxygen during photosynthesis. This helps us and other animals have clean air to breathe.

Question 20

Do flowers photosynthesize too?

Accepted Answer

Yes, the green parts of flowers photosynthesize, just like leaves. They help the plant collect sunlight and make food to grow.
