The function of the Nucleus is...
To control the operation of the cell. It contains DNA.
1 of 26
The function of Mitochondria is...
To contribute with respiration.
2 of 26
The function of Ribosomes is...
To take care of protein synthesis
3 of 26
Chloroplasts are used for...
4 of 26
The cell wall..
Supports the cell and strengthens it.
5 of 26
A tissue is..
A group of cells which are not all the same.
6 of 26
An organ is...
A group of different tissues that work together.
7 of 26
An organ system is...
A group of organs working together.
8 of 26
The equation for Photosynthesis is...
Carbon Dioxide + Water -> Glucose + Oxygen.
9 of 26
Where does Photosynthesis occur?
Inside chloroplasts.
10 of 26
What are the differences between an animal and plant cell?
Plant cells have; Permanent Vacuole, Chloroplasts and Rigid cell wall.
11 of 26
What is Diffusion?
Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration.
12 of 26
Give 2 examples of specialised cells...
Any from: Sperm, Egg, Root Hair Cell, Leaf Cell, Red Blood Cell.
13 of 26
How are leaves adapted to perform Photosynthesis?
The leaf allows sunlight to beam down onto its surface to provide energy for the process. Chlorophyll is contained in chloroplasts. Water reaches the cells via xylem. Co2 diffuses into the leaf.
14 of 26
How do plants use glucose for storage?
It is stored in seeds as Lipids. It is stored in roots, stems and leaves.
15 of 26
How are distributions of organisms measured?
By Quadrats or Transects
16 of 26
What are enzymes made from?
Biological catalysts produced by living things.
17 of 26
What do enzymes do?
Increase the rate of chemical reactions without being used up.
18 of 26
What is the place in which subtrate molecules fit?
Active site
19 of 26
What do we say if the active site no longer works?
It is denatured.
20 of 26
What are the 3 groups of enzymes in digestion?
Amylase converts starch into sugars. Protease converts proteins into amino acids. Lipase converts lipids into glycerol and fatty acids.
21 of 26
Where is amylase produced?
In the salivary glands, pancreas and small intestine.
22 of 26
Where is protease produced?
In the stomach, pancreas and small intestine.
23 of 26
Where is Lipase produced?
Pancreas and Small Intestine.
24 of 26
Why is the stomach acidic?
It helps to begin digestion, kills many harmfull microorganisms that may have been swallowed with food. Enzymes work best in acidic conditions.
25 of 26
What is bile?
Neutralises acid so to provide alkaline conditions needed in the small intestine.Bile is produced by the liver and stored in the gall bladder.
