Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is the way plants make their own food. They use sunlight, water, and air to create food and release oxygen.

Question 2

Why do plants need sunlight for photosynthesis?

Accepted Answer

Sunlight is like a battery charger for plants. It gives them energy to turn water and air into food.

Question 3

Do all plants use photosynthesis?

Accepted Answer

Most plants use photosynthesis to make food. Some plants, like mushrooms, do not use photosynthesis because they are not green.

Question 4

Why are leaves green?

Accepted Answer

Leaves are green because they contain something called chlorophyll. Chlorophyll helps plants catch sunlight for photosynthesis.

Question 5

How do plants get the water they need?

Accepted Answer

Plants soak up water through their roots, which are underground. The water travels up through the stem to reach the leaves.

Question 6

Do all plants need the same amount of sunlight?

Accepted Answer

No, some plants need lots of sunlight, while others can grow with very little. It's like how some people like a lot of light and others like dim light.

Question 7

What part of the plant uses sunlight?

Accepted Answer

The leaves use sunlight. They have a special part that absorbs sunlight to help make food.

Question 8

What is the gas called that plants take from the air?

Accepted Answer

Plants take in a gas called carbon dioxide from the air. They use it along with water and sunlight to make food.

Question 9

What is the name of the food plants make?

Accepted Answer

The food plants make is a kind of sugar. This sugar is their energy source to grow and stay healthy.

Question 10

How do plants help us when they make their food?

Accepted Answer

When plants make their food, they give off oxygen as a waste product. We need oxygen to breathe!

Question 11

Can photosynthesis happen without water?

Accepted Answer

No, water is essential for photosynthesis. Without water, plants can't mix it with sunlight and air to make food.

Question 12

Do plants perform photosynthesis at night?

Accepted Answer

No, photosynthesis needs sunlight to happen, so it only occurs during the day. At night, plants rest and use the food they made during the day.

Question 13

Why don’t underwater plants need leaves to photosynthesize?

Accepted Answer

Underwater plants can use their stems and other parts to absorb sunlight. They can also take in carbon dioxide and water directly from their surroundings.

Question 14

How do plants get rid of the oxygen they make?

Accepted Answer

Plants release oxygen through tiny holes in their leaves. The oxygen then goes into the air for us to breathe.

Question 15

Can plants grow without photosynthesis?

Accepted Answer

Most plants can't grow without photosynthesis because they won't have food to eat. They need it just like we need food to grow.

Question 16

Do plants only use light from the sun?

Accepted Answer

Plants mostly use sunlight, but they can also use light from lamps. That's why some plants can grow indoors with special lights.

Question 17

Why do some plants have thick leaves for photosynthesis?

Accepted Answer

Thick leaves can store more water and are better for plants in dry places. This helps them do photosynthesis even when there's not much water.

Question 18

Do photosynthesis and respiration happen at the same time in plants?

Accepted Answer

Yes, both can happen in plants at the same time. Photosynthesis happens when there's light, and respiration happens all the time to use the food.

Question 19

What happens if a plant gets too much sunlight?

Accepted Answer

Too much sunlight can hurt a plant. It's like getting a sunburn; the leaves can get damaged and dry out.

Question 20

Why are plants important for the planet?

Accepted Answer

Plants make oxygen for us to breathe and food for themselves and other animals. They also help keep the planet cool by using up carbon dioxide.
