?
What is the role of the nucleus?
Contains DNA and controls activities of the cell.
1 of 24
What is cytoplasm and what takes place there?
Cytoplasm is a gel-like substance and most chemical reactions happen there.
2 of 24
What is the role of the cell membrane?
It's job is to hold the cell together and to control what comes in and out of the cell.
3 of 24
What are mitochondria?
Most energy is produced from repiration due in mitochondria.
4 of 24
What are ribosomes?
Ribosomes produce protein for the plant.
5 of 24
What is the cell wall made up of and what is its role?
The cell wall is made up out of cellulose and its role is to strenghten and protect the cell from disease.
6 of 24
How do chloroplasts help the plants production of food?
Chloroplasts produce glucose for the plant by absorbing light.
7 of 24
What is DNA?
DNA is the information that a cell or organism contains.
8 of 24
What type of cell doesnt have a nucleus?
A bacterial cell does not have a nucleus.
9 of 24
What do plants have that human/animal cells do not?
Plant cells have chloroplasts whereas human and animal cells do not.
10 of 24
Which part of a plant cell contains cell sap?
The permanant vacuole in a plant cell contains cell sap.
11 of 24
What is diffusion?
Diffusion is the spreading out of particals from having a high concentration to a low concentration.
12 of 24
In diffusion, if the concentration is higher what effect does this have on the rate of diffusion?
This means that the rate of diffusion increases and becomes faster.
13 of 24
What are palisade cells?
Paliside cells are classed as specialised because they have a lot more chloroplasts than a usual plant cell would have. This means it can photosynthesise quicker and at a faster rate.
14 of 24
What is a multicellular organism?
A multicellular organism contains more than one cell. Whereas a unicellular organism only contains one. An example of a multicellular organism is a plant or a human.
15 of 24
What is the process in which a cell becomes specialised?
The process is called differentiation. This occurs when a multicellular organism starts to develop.
16 of 24
What is a tissue?
A tissue is made up out of a group of similar cells which together perform a particular function.
17 of 24
An example of a tissue function, in a human, includes...
Muscular tissue (contracts to move) , Glandular tissue (produces enzymes/hormones) , Epithelial tissue (covers parts of body)
18 of 24
What is an organ system?
An organ system is a group of organs that work together to perform a particular function.
19 of 24
Name an example of an organ system.
Digestive System.
20 of 24
(Next 2Q on DS) What do both the salivary gland and the pancreas do?
Produces digestive juices.
21 of 24
What are the roles of the stomach and liver?
Digests food and produces bile.
22 of 24
What do the large and small intenstine do?
(L) Absorbs water and leaves faeces. (S) Digests food and absorbs food molecules eg. glucose.
23 of 24
What do plants use glucose for?
Respiration, creating cell walls, protein, stored in seeds and stored as starch.
