What are all living things made up of?
Cells
1 of 31
Cells can either be...
Prokaryotic or Eukaryotic
2 of 31
What are Prokaryotic Cells?
Prokaryotic Cells are smaller and simpler. E.g. Bacteria
3 of 31
What are Eukaryotes Cells?
Eukaryotic Cells are complex and include all animal and plant cells. Eukaryotes are organisms that are made up of eukaryotic cells.
4 of 31
Nucleus?
Contains genetic material that controls the activities of the cell.
5 of 31
Cytoplasm?
gel-like substance where most of the chemical reactions happen. It contains enzymes that control theses chemical reactions.
6 of 31
Cells Membrance?
holds the cell together and controls what goes in and out.
7 of 31
Mitochondria?
these are where most of the reactions for aerobic respiration.
8 of 31
Ribosomes?
these are where proteins are made in the cell.
9 of 31
Rigid Cell Wall?
made of cellulose. It supports the cell and strengthens it.
10 of 31
Permanent Vacuole?
contains cell sap, a weak solution of sugar and salts.
11 of 31
Chloroplasts?
these are where photosynthesis occurs, which makes food for the plant. They contian a green substance called chlorophyll, which absorbs the light needed for photosynthesis.
12 of 31
Name all the different parts in a animal cell.
Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Ribosomes.
13 of 31
Name all the different parts in a plant cell.
Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Ribosomes, Rigid Cell Wall, Permanent Vacuole, Chloroplasts.
14 of 31
What is the equation for Magnification?
Magnification = Image Size / Real Size
15 of 31
What is Differentiation?
Differentiation is the process by which a cell changes to become specialised for its job.
16 of 31
What are undifferentiated cells called?
Stem Cells
17 of 31
What are Sperm Cells specialised for? and what is its function ?
Reproduction. Function - The function of a sperm is to get the male DNA to the female DNA. (It has a long tail and a streamlined head to help it swim to the egg.)
18 of 31
What are Nerve Cells specialised for? and what is its function?
Rapid Signalling. Function - The fuction of the nerve cell is to carry electrical signals from one part of the body to another.
19 of 31
What are Muscle Cells specialised for? and what is its function?
Contraction. Function - The fuction is to contract quickly.
20 of 31
What are Root Hair Cells specialised for?
absorbing Water and Minerals.
21 of 31
What are Phloem and Xylem Cells specialised for?
Transporting Substances.
22 of 31
What are Chromosomes?
Chromosomes contain genetic information.
23 of 31
What is the stage of the cell cycle called when the cell divides?
Mitosis
24 of 31
What is the Cell Cycle?
The cell cycle makes new cells for growth, development and repair.
25 of 31
What is Binary Fission?
Binary Fission is where Prokaryotic cells can reproduce using a simple cell division.
26 of 31
What are some people against stem cell research?
1) feel that human embryos shouldnt be used for experiemnts since each one is a ptential human life. 2) Others think that curing existing patients who are suffering is more important that the right of embryos. ect...

What is Diffusion?
Diffusion is the spreading out of particles from an area of higher concentration to an area of lower concentration. Diffusion happens in both solutions and gases.
28 of 31
What is Osmosis?
Osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration.
29 of 31
What is Active Transport?
Active Transport allows the plant to absorb minerals from a very dilute solution.

Give one way in which alveoli are adapted for gas exchange.
- they have a large surface area, - they have a moist lining for dissolving gases, - they have very thin walls, they have a good blood supply.
