Answer 7

Bacteria cell

Question 8

Why is it possible to see a bacterial colony but not a singular bacterium

Answer 8

A singular bacterium is too small to see

Question 9

Why do muscle cells need a lot of mitochondria

Answer 10

And undifferentiated cell with the potential to form a wide variety of different cell types

Question 11

What is diffusion

Answer 11

The movement of a substance from an area of high concentration to an area of low concentration through a partially permeable membrane- down a concentration gradient.

Question 12

Where does diffusion happen in plants

Answer 12

The movement of carbon dioxide into actively photosynthesising plant cells

Question 13

Where does the difffusion happen in the body

Answer 13

The diffusion of oxygen into the cells of the body from the bloodstream as the cells are respiring and using up oxygen

Question 14

Where else does the diffusion happen in the body?

Answer 14

The diffusion of simple sugars and amino acids from the got through cell membranes

Question 15

What is a tissue

Answer 15

I tissue is a group of cells with similar structure and functions working together

Question 16

What does muscle tissue do

Answer 16

It contracts to bring about movement

Question 17

What does glandular tissue do

Answer 17

Produces substances such as enzymes or hormones

Question 18

What does epithelial tissue do

Answer 18

Covers some parts of the body

Question 19

What is epidermal tissue in plants

Answer 19

The tissue which covers the plant

Question 20

What does the plant tissue mesophyll do

Answer 20

Photosynthesises

Question 21

What is the purpose of xylem and phloem and what do they transport?

Answer 21

Transport substances such as water and nutrients around the plant

Question 22

Where is soluble food absorbed

Answer 22

Small intestine

Question 23

Where are digestive juices produced

Answer 23

In the pancreas and salivary glands

Question 24

Where is Bile produced

Answer 24

The liver

Question 25

What happens in the large intestine

Answer 25

Water is absorbed from the undigested food producing faeces

Question 26

What is meant by the term differentiation of cells?

Answer 26

When cells start to divide they are very similar as the tissues develop the cells change to form particular cells with particular functions

Question 27

Name three organs in the human digestive system

Answer 27

Liver, small intestine, stomach

Question 28

How is a leaf cell adapted to carry out photosynthesis

Answer 28

The leaf has mesophyll tissue. The mesophyll cells contain chloroplasts which can photosynthesise

Question 29

Describe in detail what happens to food as it passes through the digestive system

Answer 29

The insoluble food is mixed with digestive juices produced by glands it is digested in the stomach and small intestine, bile produced by the liver is added to the food to help digestion, absorption of the soluble food takes place in the small intestine, water is absorbed by the large intestine

Question 30

Give two differences between a plant leaf cell and a yeast cell

Answer 30

Leaf cells have chloroplasts and the cellulose cell wall, yeast does not have chloroplasts and no Celulose in its wall

Question 31

In which part of the cell is energy released during respiration?

Answer 31

Mitochondria
