Regulates the movement of substances in and out of the cell. It also has receptor molecules on it which allow it to respond to chemicals like hormones

Cell Wall
Supports plant cells
Made from cellulose
2 of 14
Nucleus
Chromatin is made from proteins and DNA which control the cells activities. The pores in the nuclear envelope allow substances such as RNA to move between the nucleus and the cytoplasm. The nucleolus makes ribosomes.
3 of 14
Lysosome
Contains digestive enzymes. These are kept seperate from the cytoplasm by the surrounding membrane and can be used to digest invading calls or to break down worn out componants of the cell.
4 of 14
Ribosome
The site where proteins are made
5 of 14
Rough Endoplasmic Reticulum
Folds and process' proteins that have been made at the ribosomes
6 of 14
Smooth endoplasmic reticulum
Synthesises and processes lipids
7 of 14
Vesicle
Transports substances in and out of the cell (via the plasma membrane) and between organelles. Some are formed by the Golgi Apparatus or the endoplasmic reticulum while others are formed at the cell surface.
8 of 14
Mitochondria
The site of aerobic respiration where ATP is produced. They're found in very large numbers in cells that are very active and require a lot of energy.
9 of 14
Golgi Apparatus
It process' and packages new lipids and proteins. It also makes lysosomes
10 of 14
Chloroplast
The site where photosynthesis takes place. Some parts of photosynthesis happen in the grana and other parts happen in the stroma.
11 of 14
Centriole
Involved witht the separation of chromosomes during cell division
12 of 14
Cilia
The microtubules allow the cilia to move. This movement is used by the cell to move substances along the cell surface.
13 of 14
Flagellum
The microtubules contract t make the flagellum move. Flagella are used like outboard motors to propel cells forward (eg when a sperm cell swims)
