1

Living things that are made up of only one cell are known as ( unicellular organisms., multicellular organisms )
( Bacteria, Fungi, Organisms ) are small, simple cells that do not have any organelles or a true nucleus. Some bacteria cause ( diseases and infections., strength and stability, healthy bodies )

1

What are the living things found in water?

1

Unicellular organisms belong to a group called ( protists., Bacteria, Chloroplasts )

1

Mitosis is when cells divide into ( 2 identical, 3 different, 4 same ) cells.

1

( Multicellular, Unicellular, I don't know ) organisms are organisms made up of more than 1 cell.

1

Cells have a special job to do in the body and they have a structure that makes them better able to do their job.

1

About how many cells does the human body contain.

1

About how many DIFFERENT TYPES of cells are there in the human body.

1

What are the names of the 3 types of muscles in your body?

1

( Voluntary, Involuntary, Cardiac ) muscles are attached to the bones of your skeleton. Another name for it is ( skeletal, smooth, heart ) muscles.

1

( Involuntary, Voluntary, Cardiac ) muscles are muscles that work without you having to think about it for example; when you breathe you don't think about it. Another term used to describe involuntary muscles is ( smooth, skeletal, axons ) muscles.

1

( Cardiac, Involuntary, Voluntary ) muscles is the muscles that makes up the ( heart., liver., kidney. ) It is an ( involuntary, voluntary ) muscle.

1

Nerve cells make up your brain. They also carry information from your brain to other parts of your body and from your muscles back to your brain.

1

Some nerve cells have a very long fibre extending from the cell, these fibres are known as ( axons., specialized., multicellular organisms. )

1

Red blood cells carry oxygen from your lungs to your cells.

1

White blood cells help store energy.

1

Brown fat cells help produce heat for the body.

1

White fat cells are used as part of the immune system and help the body fight infections.

1

Tick 3 different specialised plant cells.

1

Tissues work together to complete a specific task.

1

An organ supports or holds together other tissues in the body.

1

Organ systems have 2 or more different organs that work together.

1

In the human body there are 4 types of tissue:
- ( Epithelial, Organs, Tissues )
- Connective
- ( Muscle, Xylem, Phloem )
- Nerve

1

The ( skin, leg, tongue ) is the largest organ in the human body.

1

3 different types of systems in your body are:

1

The 2 types of cells in a vascular tissues are Xylem and Phloem.
