Plasma surface cell
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
Supports plant cells
Made from cellulose
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.
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.
The site where proteins are made
Rough Endoplasmic Reticulum
Folds and process' proteins that have been made at the ribosomes
Smooth endoplasmic reticulum
Synthesises and processes lipids
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.
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.
It process' and packages new lipids and proteins. It also makes lysosomes
The site where photosynthesis takes place. Some parts of photosynthesis happen in the grana and other parts happen in the stroma.
Involved witht the separation of chromosomes during cell division
The microtubules allow the cilia to move. This movement is used by the cell to move substances along the cell surface.
The microtubules contract t make the flagellum move. Flagella are used like outboard motors to propel cells forward (eg when a sperm cell swims)
