Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is the process by which plants make their own food. They use sunlight, water, and air to create a sugar called glucose, which helps them grow.

Question 2

Why do plants need sunlight for photosynthesis?

Accepted Answer

Sunlight gives plants energy to turn air and water into food. Without sunlight, plants can't make the energy they need to live.

Question 3

Can photosynthesis happen without water?

Accepted Answer

No, water is an important ingredient for photosynthesis. Plants use water to help change sunlight and air into food.

Question 4

How does photosynthesis help us breathe?

Accepted Answer

During photosynthesis, plants make oxygen as a by-product, which is released into the air. We need oxygen to breathe and stay alive.

Question 5

Do all plants use photosynthesis?

Accepted Answer

Yes, all green plants use photosynthesis to make their food. This process is crucial for their survival and growth.

Question 6

Can photosynthesis occur underwater?

Accepted Answer

Yes, underwater plants can do photosynthesis. They use sunlight that reaches through the water to make their food.

Question 7

How do desert plants do photosynthesis?

Accepted Answer

Desert plants have adaptations that help them store water and survive. They often do photosynthesis when it's cooler, like at night, to save water.

Question 8

Why are leaves green?

Accepted Answer

Leaves are green because they have a substance called chlorophyll, which helps plants capture sunlight. Chlorophyll is what makes them look green.

Question 9

Can plants do photosynthesis at night?

Accepted Answer

Most plants do not, because they need sunlight for photosynthesis. However, some desert plants store energy from the sun during the day and use it at night.

Question 10

How do plants in forests perform photosynthesis with limited light?

Accepted Answer

Forest plants may have larger leaves to catch more sunlight. They can still photosynthesize even with less light, but it might happen more slowly.

Question 11

Do indoor plants perform photosynthesis?

Accepted Answer

Yes, indoor plants perform photosynthesis using sunlight that comes inside or even artificial light. They still need enough light to make their food.

Question 12

What are stomata and how do they help photosynthesis?

Accepted Answer

Stomata are tiny openings in leaves that let air in and out. They help plants take in the air they need for photosynthesis.

Question 13

Why is carbon dioxide important for photosynthesis?

Accepted Answer

Plants use carbon dioxide from the air to make food during photosynthesis. It's one of the main ingredients, along with sunlight and water.

Question 14

How does photosynthesis differ in very cold environments?

Accepted Answer

In cold places, plants may do photosynthesis more slowly because it's harder to capture sunlight and the water may freeze. But they adapt to make the most of the available conditions.

Question 15

What happens if a plant does not get enough sunlight?

Accepted Answer

If a plant doesn't get enough sunlight, it can't make enough food to grow strong. It might become weak and may not survive.

Question 16

Why are some plants not green?

Accepted Answer

Some plants have different colors because their leaves have other pigments besides chlorophyll. They still do photosynthesis but also protect themselves from too much sunlight or attract insects.

Question 17

How do plants on mountains perform photosynthesis?

Accepted Answer

Plants on mountains are often adapted to catch sunlight quickly and make use of any available water. They usually grow in ways that help them face the sun directly.

Question 18

Do artificial lights help plants do photosynthesis?

Accepted Answer

Yes, artificial lights can help plants when there’s not enough sunlight. Special grow lights mimic sunlight so plants can still make food and grow indoors.

Question 19

Can photosynthesis clean the air?

Accepted Answer

Yes, photosynthesis can help clean the air by taking in carbon dioxide and releasing oxygen. This process makes the air fresher and healthier to breathe.

Question 20

Do plants perform photosynthesis in the winter?

Accepted Answer

In winter, photosynthesis slows down because of less sunlight and colder temperatures. Some plants go dormant or slow their growth until it gets warmer.
