What's a cell wall and what is it made of?

The outer layer of the plant cell that keeps it strong and stiff. It is made of cellulose.

All animals are made of....

cells.

Does a red blood cell have a nucleus? Why?

No, it doesn't. The cell needs space for haemoglobin, which carries oxygen around the body.

100

what is a tissue?

A group of similar cells who all work together to carry out a function.

Where do we find palisade cells? Be specific.

In plants, specifically leaves.

200
TRUE OR FALSE:

Animal don't have a cell wall.

TRUE.

200
Why are red blood cells so tiny and flexible?

Because they need to get into the tiniest capillaries.

200
Where do we find ciliated epithelium?
In the lining of our air tubes.

What is the function of chloroplasts?
Chloroplasts is where plants make their food through photosynthesis. They contain chlorophyll, responsible for the color green of the leaf.
300
What is the function of the nucleus?

It regulated chemical activities in the cell and it contains DNA.

What is an axon and where do we find it?

It's a long strand of cytoplasm in the neurone. Electrical signals travel along this very quickly!

A set of organs that all work together to carry out a function is called.... (give examples)

An organ system (respiratory system)

400

The organelle where energy is released from food.

Mitochondria.

What are cilia for?

Cilia are tiny hairs situated on top of ciliated cells. They trap bacteria and viruses with their mucus and sweep them back up so they don't enter our lungs.

Name two tissued found in a plant leaf.

Upper epidermis

Palisade layer

The solution inside the sap vacuole is called...

Cell sap.

How many cells are estimated to be in a person?

Around 100 trillion.

500
How have root hair cells adapted for their function?

They have a long, thin extension to help them soak up water from the soil. This way, water will move easily from the soil to the cell.
