What do both animals and plant cells contain?
Nucleus, Cytoplasm, Cell membrane, Mitochondria and Ribosomes
1 of 30
What do ONLY plant cells contain?
Cell walls, chloroplasts, Permenant Vacuole
2 of 30
What does the nucleus contain and what does it do?
Contains genetic material which controls the activity of the celll
3 of 30
What happens in the Cytoplasm and what is it controlled by?
Most chemical processes take place here and it is controlled by enzymes
4 of 30
What does the cell membrane do?
Controls the movement of substances into and out of the cell
5 of 30
What happens in the mitochondria?
Most energy is released by respiration here
6 of 30
What happens in the ribosomes?
Protien systhesis happens here
7 of 30
What does a Cell Wall do?
Strengthen the cell
8 of 30
What do chloroplasts contain and what does it do?
Contains chlorophyll which absorbs light energy for photosynthesis
9 of 30
What is the permenant vacuole filled with and what does this help to do?
Cell Sap, to help keep the cell turgid.
10 of 30
What does a bacterium cell consist of?
Cytoplasm and a membrane surrounded by a cell wall
11 of 30
What is different about a bacterium cell?
The genetic matrerial is not in a distinct nucleus
12 of 30
What does a yeast cell consist of?
Nucleus, cytoplasm and a membrane surrounded by a cell wall
13 of 30
What are both Bacteria and Yeast cells?
Single-celled organsisms
14 of 30
What is Diffusion?
The spreading out of particles from a region where they are of a higher concentration to region with a lower concentration
15 of 30
Name one example of diffusion in the body....
In the lungs particles move oxygen from the alvelolar air space to the blood circulating around the lungs
16 of 30
Define: Differentiation
The process by which a cell becomes a specialised type of cell
17 of 30
Name the three types of tissues
Muscular, Glandular and Epithelial
18 of 30
What does the Muscular tissue do?
Contracts, bringing about movement
19 of 30
What does the Glandular tissue do?
Produces substances such as enzymes and hormones
20 of 30
What does the Epithelial tissue do?
Covers some parts of the body
21 of 30
In what order does organs, cells, organ systems and tissues go?
Cells, Tissues, Organs, Organ Systems
22 of 30
In the stomach what does the muscular tissue do?
Churn the fod and other contents of the stomach
23 of 30
In the stomach what does the glandular tissue do?
Produce digestive juices such as acids and enzymes
24 of 30
In the stomach what does the Epithielial issue do?
Cover the inner and outer surfaces of the stomach
25 of 30
What are the four main organ systems in the body?
Nervous, respitory, reproductive and digestive
26 of 30
What parts of the body are involved in the digestive system and what do they do?
Glands- produce digestive juices, Stomach and small intestine - where digestion occurs, Liver - produces bile, Small instestine - digest food, Big intestine - Produces faeces
27 of 30
What are the three types of tissues in a plant and what are their purposes?
Epidermal tissues which cover the plant, Mesophyll which carries out photosynthesis and Xylem and pholem which transport substances around the plant
28 of 30
What organs does a plant contain?
Stem, root and leaves
29 of 30
How are plants adapted to absorb sunlight for photosynthesis?
Large surface area - absorb more, thin - short distance for carbon dioxide to diffuse and chloryophyll - to absorb more sunlight
