Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is the process where plants, algae, and some bacteria turn sunlight into food. They use sunlight, carbon dioxide, and water to make sugar and oxygen.

Question 2

Why do plants need sunlight?

Accepted Answer

Plants need sunlight because it's the energy source they use to make food during photosynthesis. Without sunlight, they wouldn't be able to grow or survive.

Question 3

What do plants produce during photosynthesis?

Accepted Answer

During photosynthesis, plants produce sugar and oxygen. The sugar is used for food, and the oxygen is released into the air for us to breathe.

Question 4

How do plants get the water they need for photosynthesis?

Accepted Answer

Plants get water from the soil through their roots. The roots absorb the water and send it up to the leaves where photosynthesis happens.

Question 5

Why is photosynthesis important for animals?

Accepted Answer

Photosynthesis is important for animals because it produces oxygen, which animals need to breathe. Also, it creates food that animals eat, either directly as plants or indirectly through other animals.

Question 6

What part of the plant does photosynthesis mainly happen in?

Accepted Answer

Photosynthesis mainly happens in the leaves of the plant. The leaves have special cells with chlorophyll that capture sunlight to help make food.

Question 7

What do plants use carbon dioxide for?

Accepted Answer

Plants use carbon dioxide from the air to help make sugar during photosynthesis. The carbon dioxide is combined with water and sunlight to produce food for the plant.

Question 8

Can photosynthesis happen without sunlight?

Accepted Answer

No, photosynthesis cannot happen without sunlight. Sunlight is the energy plants need to make their food.

Question 9

What is chlorophyll?

Accepted Answer

Chlorophyll is the green pigment in plants that helps them capture sunlight. It's what makes leaves look green.

Question 10

How does photosynthesis help clean the air?

Accepted Answer

Photosynthesis helps clean the air by taking in carbon dioxide and releasing oxygen. This makes the air fresher and better for all living things to breathe.

Question 11

Do all plants perform photosynthesis?

Accepted Answer

Nearly all plants perform photosynthesis, but a few plants like some parasitic plants do not. These exceptions get their nutrients from other sources.

Question 12

How does photosynthesis affect the food chain?

Accepted Answer

Photosynthesis is the start of the food chain. Plants make food using sunlight, and then animals eat the plants, and other animals eat those animals.

Question 13

Why are trees important for photosynthesis?

Accepted Answer

Trees are important because they have lots of leaves that do a lot of photosynthesis, producing big amounts of oxygen. This oxygen is crucial for life on Earth.

Question 14

Does photosynthesis happen all year round?

Accepted Answer

Photosynthesis usually happens when it's warm and sunny. In some places, during winter or at night, it slows down or stops because it's too cold or dark.

Question 15

Can algae perform photosynthesis?

Accepted Answer

Yes, algae can perform photosynthesis. Like plants, they use sunlight to make their food and are important for making oxygen in the water.

Question 16

Why is photosynthesis important for energy on Earth?

Accepted Answer

Photosynthesis is important because it turns sunlight into energy that plants use to grow. This energy also supports animals and humans who eat plants or plant-eating animals.

Question 17

How long has photosynthesis been happening on Earth?

Accepted Answer

Photosynthesis has been happening for billions of years. It started long before humans existed, and it has helped shape life on Earth since then.

Question 18

What would happen if photosynthesis stopped?

Accepted Answer

If photosynthesis stopped, eventually there would be no more oxygen for us to breathe, and food would run out. Living things that depend on plants for food would have a hard time surviving.

Question 19

Do bacteria perform photosynthesis?

Accepted Answer

Some bacteria, like cyanobacteria, do perform photosynthesis. They contribute oxygen to the atmosphere just like plants do.

Question 20

How can we help plants do photosynthesis?

Accepted Answer

We can help plants do photosynthesis by planting trees and taking care of green spaces. Also, reducing pollution helps plants grow better and make more oxygen.
