Q

Is the cell wall freely permeable or partially permeable.
Explain what it means

A

Freely permeable
It allows all the substances to go in and out

17
Q

Where is most of the energy from respiration released?

A

The mitochondria
Mitochondria is used in cells that require lots of energy in respiration

18
Q

Give 3 examples of characteristics only ever found in plant cells

A

Cell wall
Permanent vacuole (animals can have temporary vacuoles)
Chloroplasts

19
Q

What carbohydrate is the cell wall made up of

A

Cellulose

20
Q

What is cellulose

A

A carbohydrate that makes up a cell walls

21
Q

Why is it important for a plant to absorb water

A

Because when a plant abosrbs water, it goes into the vacuole which then expands and pushes outwards against the cell wall giving the plant support

22
Q

Define porous

A

Accepts water
(Doesn’t reject water)

23
Q

When do plants develop a vacuole

A

When they are mature and fully grown

24
Q

What substance is held in the vacuole

A

Sap
(A watery substance)

25
Q

What does sap store

A

Proteins, dissolved sugars, minerals and other solutes

26
Q

What is a solute

A

A dissolvable substance

27
Q

What is a solvent

A

A liquid that can dissolve solutes

28
Q

Can animals have vacuoles?

A

Yes, but they are only small and temporary structures

29
Q

What do chloroplasts absorb?

A

Light energy

30
Q

What do chloroplasts make in the process of photosynthesis

A

Food

31
Q

What is the green pigment in a plant called?

A

Chlorophyll

32
Q

What parts of the plant doesn’t contain chlorophyll

A

Roots
Flower
Woody stems

33
Q

What characteristics do plant and animal cells have in common (4)

A

Mitochondria
Cytoplasm
Nucleus
Cell membrane
Ribosomes

34
Q

Where do chemical reactions take place in a plant?

A

The cytoplasm

35
Q

What generates most of the chemical energy needed?

A

The mitochondria

36
Q

How can you tell if a cell can generate its own food.
From where do they get it

A

If a plant is green therefore contains chloroplasts it means that the cell can generate its own food from the sun
