Question 1

What is photosynthesis?

Accepted Answer

Photosynthesis is the way plants use sunlight to make their own food. They take in sunlight, water, and carbon dioxide to produce energy and oxygen.

Question 2

Why do plants need sunlight?

Accepted Answer

Plants need sunlight to create energy. Sunlight helps them turn water and air into food they can use to grow.

Question 3

What do plants produce during photosynthesis?

Accepted Answer

During photosynthesis, plants produce sugar, which is their food, and oxygen, which they release into the air.

Question 4

What would happen if photosynthesis stopped?

Accepted Answer

If photosynthesis stopped, plants wouldn't be able to make food, and they'd die. Animals and humans wouldn't have enough oxygen to breathe and plants to eat.

Question 5

Why is photosynthesis important for humans?

Accepted Answer

Photosynthesis is important for humans because it creates oxygen, which we need to breathe. It also provides food, as plants are the base of our food chain.

Question 6

What are chlorophyll and what role do they play in photosynthesis?

Accepted Answer

Chlorophyll is the green pigment in plants that captures sunlight. It helps plants to turn sunlight into the energy they need to make food.

Question 7

What are the main ingredients for photosynthesis?

Accepted Answer

The main ingredients for photosynthesis are sunlight, water, and carbon dioxide. Plants use these to make food and oxygen.

Question 8

Can photosynthesis happen at night?

Accepted Answer

No, photosynthesis cannot happen at night because plants need sunlight to start the process. Without sunlight, they can't make food.

Question 9

Do all plants perform photosynthesis?

Accepted Answer

Yes, nearly all plants perform photosynthesis because they need it to survive. Some bacteria and algae can also do photosynthesis.

Question 10

How does carbon dioxide get into the plants?

Accepted Answer

Carbon dioxide gets into plants through small openings in their leaves called stomata. The plants use it along with water and sunlight to make food.

Question 11

What happens to the oxygen produced in photosynthesis?

Accepted Answer

The oxygen produced in photosynthesis is released into the air for humans and animals to breathe. It's a very important part of keeping the air healthy for us.

Question 12

How do plants get water for photosynthesis?

Accepted Answer

Plants get water from the soil through their roots. The water moves up through the plant to the leaves where photosynthesis happens.

Question 13

If a plant is in the shade, can it still do photosynthesis?

Accepted Answer

A plant in the shade can still do photosynthesis, but it might not be as strong. Plants need enough sunlight to make enough food.

Question 14

How do leaves help in photosynthesis?

Accepted Answer

Leaves help in photosynthesis by capturing sunlight and taking in air. They have a large surface area that helps absorb more sunlight.

Question 15

What is glucose and how does it relate to photosynthesis?

Accepted Answer

Glucose is a type of sugar that plants make during photosynthesis. It's the food that gives them the energy to grow and stay healthy.

Question 16

Why are plants green?

Accepted Answer

Plants are green because of chlorophyll, the pigment that helps them catch sunlight for photosynthesis. Chlorophyll reflects green light, and that's what we see.

Question 17

What is the first step of photosynthesis?

Accepted Answer

The first step of photosynthesis is when plants absorb sunlight using chlorophyll. This sunlight gives them the energy to turn water and carbon dioxide into food.

Question 18

Can photosynthesis happen in water plants?

Accepted Answer

Yes, water plants can do photosynthesis. They use sunlight that travels through water and use carbon dioxide from the water to make food.

Question 19

Do animals do photosynthesis?

Accepted Answer

No, animals don't do photosynthesis. Only plants, some bacteria, and algae can make their own food using sunlight.

Question 20

Is photosynthesis happening all year round?

Accepted Answer

Photosynthesis mostly happens in the warmer months when there's plenty of sunlight. In winter, when it's darker and colder, many plants slow down the process or rest.
