Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is the process plants use to make their food. They use sunlight, water, and carbon dioxide to create oxygen and sugar, which they use to grow and stay healthy.

Question 2

Why do plants need sunlight?

Accepted Answer

Plants need sunlight because it gives them the energy to make their food. It's like how we need food to get energy to play and learn.

Question 3

What do plants make during photosynthesis?

Accepted Answer

During photosynthesis, plants make oxygen and sugar. The sugar is their food, and the oxygen goes into the air for us to breathe.

Question 4

Why is photosynthesis important for humans?

Accepted Answer

Photosynthesis is important for us because it produces oxygen, which we need to breathe. It also helps plants grow, which gives us food to eat.

Question 5

Do all plants do photosynthesis?

Accepted Answer

Yes, almost all plants do photosynthesis. They need it to make their food and stay alive.

Question 6

Can photosynthesis happen at night?

Accepted Answer

No, photosynthesis can't happen at night because plants need sunlight to do it. At night, plants can't make food, but they rest and prepare for the next day.

Question 7

What do plants use water for in photosynthesis?

Accepted Answer

Plants use water to help make their food during photosynthesis. The water combines with carbon dioxide, using sunlight energy, to create sugar and oxygen.

Question 8

How do plants get water for photosynthesis?

Accepted Answer

Plants get water through their roots. The roots soak up the water from the soil and send it up through the plant.

Question 9

What is carbon dioxide and why do plants need it?

Accepted Answer

Carbon dioxide is a gas in the air that people and animals breathe out. Plants need it to make their food during photosynthesis.

Question 10

How do plants take in carbon dioxide?

Accepted Answer

Plants take in carbon dioxide through tiny holes in their leaves called stomata. These holes let the gas in so the plant can use it to make food.

Question 11

What role do leaves play in photosynthesis?

Accepted Answer

Leaves are like the food factories of plants. They capture sunlight and have the parts needed to turn sunlight, water, and carbon dioxide into food and oxygen.

Question 12

Do plants use all the sunlight they get?

Accepted Answer

Plants don't use all the sunlight they get; they only use what they need to make food. The extra sunlight just keeps them warm or reflects off them.

Question 13

Why do leaves look green?

Accepted Answer

Leaves look green because they contain a special pigment called chlorophyll. Chlorophyll absorbs sunlight and helps make food during photosynthesis.

Question 14

What happens to the sugar plants make?

Accepted Answer

The sugar plants make gives them energy to grow, make flowers, and produce seeds. It’s like their food to keep them strong and healthy.

Question 15

Can plants survive without photosynthesis?

Accepted Answer

Plants can't survive without photosynthesis because they can't make the food they need. Just like we need food, plants need photosynthesis to get their energy.

Question 16

Why is oxygen important to us?

Accepted Answer

Oxygen is important because we need it to breathe and live. Plants give off oxygen during photosynthesis, which goes into the air and helps everyone breathe.

Question 17

How do plants help the environment with photosynthesis?

Accepted Answer

Plants help the environment by cleaning the air and making oxygen through photosynthesis. They also absorb carbon dioxide, which helps keep the air clean and healthy.

Question 18

What happens to the oxygen plants make?

Accepted Answer

The oxygen plants make goes back into the air. It becomes part of the air that people and animals breathe in to stay alive.

Question 19

Is photosynthesis the same in all plants?

Accepted Answer

Photosynthesis is mostly the same in all plants. They all need sunlight, water, and carbon dioxide, but some plants might do it in slightly different ways depending on where they live.

Question 20

How does photosynthesis affect the air we breathe?

Accepted Answer

Photosynthesis affects the air by adding oxygen and removing carbon dioxide. This keeps the air fresh and healthy for us to breathe.
