Q

What are the Characteristics of plants?

A

Contains chloroplasts and carry out photosynthesis
Store carbohydrates as starch or sucrose
Cellulose cell walls
Multi cellular organisms

16
Q

Examples of plants

A

Maize
Peas
Whisk fern

17
Q

What are the characteristics of an animal cell?

A 
Do not contain chloroplasts, so it can't carry out photosynthesis. 
Multicellular organisms
Have no organisms
No cell wall 
Store carbohydrates as glycogen
18
Q

Examples of animal living organisms

A

Frog
Shield bug
Kangaroo
Box jellyfish

19
Q

Description of organelle

A

Cell structure that is specialised to carry out a particular function or job

20
Q

What is the Structure of cell?

A

Basic structural and functional unit of a living organism

21
Q

Function of tissue

A

Group of cells with similar structures, working together to perform a shared function.

22
Q

Function of an organ

A

Structure made up of a group of tissues, working together to perform specific function.

23
Q

Function of organ system

A

Group of organs with related functions, working together to perform body functions

24
Q

What organisms are red blood cells found in?

A

Found in blood vessels and animals.

25
Q

What is the role of red blood cells and what is special about them?

A

Carry oxygen around the body.

They are special because they have a large surface area, for oxygen to pass through. It is biconcave.

26
Q

What organisms are nerve cells found in?

A

All over the body and in animals

27
Q

What is the nerve cells role?

A

Carries nerve impulses to different parts of the body.

28
Q

What special features do nerve cells have?

A

It is long

There are connections at each end

29
Q

What organisms are palisade cells found in (leaf)?

A

Found in a leaf of a plant

30
Q

What is the palisade cells role?

A

Photosynthesis

31
Q

What special features does the palisade have?

A

They have lots of chloroplasts

32
Q

What organisms are sperm found in?

A

Male reproductive system

33
Q

What is the sperms role?

A

Genetical information and carries DNA. Fertilises the egg.

34
Q

What special features does the sperm have?

A

Tail stream lined lots of mitochondria for energy.

35
Q

What organisms are root hair cells found in?

A

Plant roots

36
Q

What is the role of a root hair cell?

A

It absorbs water and nutrients

37
Q

What special features does root hair have?

A

A large surface area to help absorb. Thin cell walls.
