Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is a process where plants use sunlight to make food. They take in carbon dioxide and water, and with the help of sunlight, make sugar and oxygen.

Question 2

Why is photosynthesis important?

Accepted Answer

Photosynthesis is important because it helps plants grow and provides food for other living things. It also gives us oxygen to breathe.

Question 3

Do all plants do photosynthesis the same way?

Accepted Answer

Most plants do photosynthesis in similar ways, but they might use different methods depending on where they live. For example, desert plants have special tricks to save water while doing photosynthesis.

Question 4

How do plants get the sunlight they need?

Accepted Answer

Plants have green parts called leaves that collect sunlight. The leaves act like little solar panels, capturing energy from the sun.

Question 5

What happens to the oxygen that plants make?

Accepted Answer

The oxygen that plants make is released into the air. This is the oxygen that humans and animals breathe.

Question 6

How do desert plants do photosynthesis?

Accepted Answer

Desert plants often open their pores at night to take in carbon dioxide, which helps them save water. They store the carbon dioxide and use it to do photosynthesis when the sun is out.

Question 7

Can photosynthesis happen without sunlight?

Accepted Answer

No, sunlight is a key ingredient in photosynthesis. Without sunlight, plants can't make food.

Question 8

Why are leaves green?

Accepted Answer

Leaves are green because they contain a special substance called chlorophyll. Chlorophyll helps plants capture sunlight for photosynthesis.

Question 9

Do all ecosystems have the same type of plants for photosynthesis?

Accepted Answer

No, different ecosystems have different types of plants adapted to their environments. For example, rainforests have tall trees, while ponds have underwater plants that also do photosynthesis.

Question 10

What role do algae play in photosynthesis?

Accepted Answer

Algae are water plants that also do photosynthesis. They make food and release oxygen just like land plants, helping support life in aquatic ecosystems.

Question 11

How do trees in cold climates do photosynthesis?

Accepted Answer

Trees in cold climates often have needle-like leaves that help save water. They still use sunlight to do photosynthesis but often at a slower pace during the cold months.

Question 12

Why do plants need water for photosynthesis?

Accepted Answer

Plants use water during photosynthesis to help turn sunlight into food. Water is also combined with carbon dioxide to create sugar and oxygen.

Question 13

Can plants grow without photosynthesis?

Accepted Answer

Plants need photosynthesis to grow because it's how they make their food. Without it, they would not have the energy to grow and survive.

Question 14

How do aquatic plants get sunlight underwater?

Accepted Answer

Aquatic plants are often close to the water surface so that sunlight can reach them. Sunlight can travel through water, allowing these plants to do photosynthesis.

Question 15

Do plants photosynthesize at night?

Accepted Answer

Plants don't do photosynthesis at night because they need sunlight to make food. However, some plants take in carbon dioxide at night to use during the day.

Question 16

How does photosynthesis help animals?

Accepted Answer

Photosynthesis helps animals by providing oxygen for them to breathe and because plants are a source of food for many animals.

Question 17

What is the main gas that plants need for photosynthesis?

Accepted Answer

The main gas that plants need for photosynthesis is carbon dioxide. They take it from the air through their leaves.

Question 18

Do fungi do photosynthesis?

Accepted Answer

No, fungi don't do photosynthesis. They get their food from breaking down other materials, like decaying plants and animals.

Question 19

Why do some plants have waxy leaves?

Accepted Answer

Some plants have waxy leaves to help keep water from evaporating. This is especially helpful in dry or sunny places.

Question 20

How do rainforests contribute to Earth's oxygen?

Accepted Answer

Rainforests contribute a lot of Earth's oxygen because they have many trees that use photosynthesis. They are sometimes called 'the lungs of the Earth' for this reason.
