Question 1

What is a cell?

Accepted Answer

A cell is like a tiny building block that makes up all living things. It's so small you need a microscope to see it.

Question 2

What do cells do?

Accepted Answer

Cells help keep living things alive by doing important jobs like making energy and helping us to grow.

Question 3

What are the main parts of a cell?

Accepted Answer

The main parts of a cell are the cell membrane, the nucleus, and the cytoplasm. Think of them as the walls, the brain, and the jelly inside the cell.

Question 4

What does the cell membrane do?

Accepted Answer

The cell membrane is like a skin that holds the cell together and lets good things in and keeps bad things out.

Question 5

What is the nucleus?

Accepted Answer

The nucleus is like the brain of the cell. It holds all the instructions for how the cell should work and grow.

Question 6

Why do cells need energy?

Accepted Answer

Cells need energy to do their jobs, like making things and moving around. They get energy from the food we eat.

Question 7

What's inside the cytoplasm?

Accepted Answer

The cytoplasm is the jelly-like stuff inside the cell where all the cell's parts float around. It's full of tiny machines that help the cell work.

Question 8

How do cells make more cells?

Accepted Answer

Cells make more cells by splitting in half in a process called cell division. This helps us grow and heal when we get a cut.

Question 9

Are all cells the same?

Accepted Answer

No, cells can be very different depending on what they do. Some cells are small and round, while others are long and stretchy.

Question 10

What are plant cells?

Accepted Answer

Plant cells are the building blocks of plants. They have a special box-like shape and have a part called a chloroplast that helps them make food from sunlight.

Question 11

What is a chloroplast?

Accepted Answer

A chloroplast is a part of a plant cell that helps turn sunlight into food through a process called photosynthesis. It's what makes plants green.

Question 12

What are animal cells?

Accepted Answer

Animal cells are the building blocks of animals, including humans. They are rounder than plant cells and do not have chloroplasts.

Question 13

Why are cells important?

Accepted Answer

Cells are important because they make up every part of our body and help us stay alive. Without cells, we wouldn't be here!

Question 14

What are stem cells?

Accepted Answer

Stem cells are special cells that can become different types of cells in the body. They are like shape-shifters that help us grow and heal.

Question 15

How do cells communicate?

Accepted Answer

Cells communicate by sending tiny chemical messages to each other. It's like they are sending little notes to share important information.

Question 16

What happens when cells don't work properly?

Accepted Answer

When cells don't work properly, it can make us sick. Our body tries to fix or replace the bad cells to help us get better.

Question 17

How do scientists study cells?

Accepted Answer

Scientists use special tools, like microscopes, to see cells up close and learn how they work. They also do experiments to see how cells react to different things.

Question 18

What is a cell wall?

Accepted Answer

A cell wall is a strong outer layer found in plant cells. It helps support and protect the cell, kind of like a suit of armor.

Question 19

Do all cells have a nucleus?

Accepted Answer

Not all cells have a nucleus. Some simple cells, like bacteria, don't have one, but they still manage to do their jobs.

Question 20

How do cells grow?

Accepted Answer

Cells grow by taking in nutrients and then making more parts inside them. When they get big enough, they can split into two smaller cells.
