Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is a process that plants use to turn sunlight into food. They take in sunlight, water, and carbon dioxide and turn them into oxygen and sugar, which they use to grow.

Question 2

Why is photosynthesis important?

Accepted Answer

Photosynthesis is important because it provides food for plants and oxygen for us to breathe. Without photosynthesis, there wouldn’t be enough oxygen in the air for animals and humans.

Question 3

What do plants need for photosynthesis?

Accepted Answer

Plants need sunlight, water, and carbon dioxide to do photosynthesis. These are the ingredients that help them make their food.

Question 4

Where does photosynthesis take place in a plant?

Accepted Answer

Photosynthesis happens mostly in the leaves of the plant. The leaves have special cells that help capture sunlight.

Question 5

What is the role of sunlight in photosynthesis?

Accepted Answer

Sunlight gives plants the energy they need to change water and carbon dioxide into food and oxygen. It's like the power source for the whole process.

Question 6

What do plants produce during photosynthesis?

Accepted Answer

During photosynthesis, plants produce oxygen and sugar. The oxygen is released into the air, and the sugar is used as food by the plant.

Question 7

How do plants get carbon dioxide for photosynthesis?

Accepted Answer

Plants take in carbon dioxide from the air. They have tiny openings on their leaves called stomata where the carbon dioxide enters.

Question 8

Can photosynthesis happen without sunlight?

Accepted Answer

No, plants need sunlight to perform photosynthesis. Without sunlight, they can’t make their food.

Question 9

Do all plants use photosynthesis?

Accepted Answer

Yes, almost all plants use photosynthesis to make food. Some exceptions are special plants like those that grow in the dark, but they often rely on other methods.

Question 10

What happens to the oxygen produced in photosynthesis?

Accepted Answer

The oxygen produced during photosynthesis is released into the air. We breathe this oxygen, which helps keep us alive.

Question 11

Why do leaves look green?

Accepted Answer

Leaves look green because of a pigment called chlorophyll. Chlorophyll captures sunlight and helps the plant make food, and it reflects green light.

Question 12

Can photosynthesis happen at night?

Accepted Answer

Photosynthesis cannot happen at night because there is no sunlight. However, plants continue to breathe and stay alive by using the food they made during the day.

Question 13

How does water help in photosynthesis?

Accepted Answer

Water is one of the main ingredients plants use in photosynthesis. Plants take water from the soil through their roots and use it to make food.

Question 14

Do plants use all the sugar they make?

Accepted Answer

Plants use some of the sugar for their own food and energy. The rest is stored or used to help the plant grow bigger.

Question 15

What role do roots play in photosynthesis?

Accepted Answer

Roots absorb water and minerals from the soil, which are needed for photosynthesis. They help keep the plant supported and healthy.

Question 16

How is photosynthesis related to the food chain?

Accepted Answer

Photosynthesis is the start of the food chain. Plants make food using the sun’s energy, and animals eat plants, making them a critical source of energy for all life.

Question 17

Do underwater plants perform photosynthesis?

Accepted Answer

Yes, underwater plants can also perform photosynthesis. They use sunlight that passes through the water to make their food.

Question 18

What happens if a plant doesn’t get enough sunlight?

Accepted Answer

If plants don’t get enough sunlight, they can’t make enough food to grow. They might become weak and their leaves might turn yellow.

Question 19

What is stomata in leaves?

Accepted Answer

Stomata are tiny holes on the surface of leaves. They let carbon dioxide in and oxygen out during photosynthesis.

Question 20

Why do we say plants make their own food?

Accepted Answer

We say plants make their own food because they use sunlight to turn water and carbon dioxide into sugars they can eat. This is different from animals who must eat plants or other animals for energy.
