Cell Membrane
Controls what enters and leaves the cell. Holds cell together
1 of 16
Nucleus
Contains genetic material that controls the activites of the cell
2 of 16
Ribosomes
Where protiens are made
3 of 16
Mitochondria
Where most of the reactions for respiration take place. Respiration releses energy the cell needs to work.
4 of 16
Cytoplasm
Gel like substance where most of the chemical reactions happen. Contains enzymes that control these chemical reactions.
5 of 16
Cell Wall
Animal cells only. Made of cellulose. Supports and strengthens cell.
6 of 16
Permanent Vacuole
Contains cell sap, weak solution of sugar and salts. Storage space.
7 of 16
Chloroplasts
Where photosynthesis occurs. Makes food for the plant, contain green substance called chlorophyll.
8 of 16
Bacterial Cell
Single celld microrganism. No nucleus genetic materal floats in cytoplasm
9 of 16
Flagella
Used for movement so the bacteria cell can swim
10 of 16
Capsule
A Protective layer to help stop white bloods cell attacking bacterial cell
11 of 16
Piili
Helps bacterial cell attach itself to tissues
12 of 16
How do yeast and bacterial cells reproduce?
Asexually as there is only one parrent. The offsprig is genetically identical to the parent cell.
13 of 16
Benefits of using Yeast
Used to produce bread- helps it rise as bubble produced in dough. Allow the fermentation of sugars- helps to mkae beer and wine.
14 of 16
Similarities between yeast and bacteral cells
Both single-celled microorganisms. Both have ccytoplasm, cell membrane and cell wall
15 of 16
Diifusion
The movement of particles from a high concentration to an area of low concentration
