Nucleus Description and Function
Surrounded by nuclear membrane with nuclear pores. Contains chromatin and nucleolus. Controls cells activities, nucleolus makes ribosomes, pores allow substances to move between nucleus.
1 of 9
Lysosome Description and Function
Round organelle surrounded by a membrane. Contains digestive enzymes that are kept separate from cytoplasm by bounding membrane. Can be used to digest invading cells or to break down worn out components of cell.
2 of 9
Ribosome Description and Function
Small organelle that floats in the cytoplasm or is attached to the rough endoplasmic recticulum. Made of proteins and RNA and not surrounded by membrane. This is where proteins are made.
3 of 9
Rough Endoplasmic Rectiulum Description and Function
System of membranes enclosing a fluid filled space, surface covered in ribosomes. Folds and processes proteins that have been made at the ribosomes.
4 of 9
Smooth Endoplasmic Recticulum Description and Function
Same as rough endoplasmic recticulum but with no ribosomes. This synthesises and processes lipids.
5 of 9
Golgi Apparatus Description and Function
Fluid filled, membrane bound, flattened sacs - vesicles seen at the end of sacs. Processes and packages new lipids and proteins and makes lysosomes.
6 of 9
Mitochondrion Description and Function
Double membrane with inner one folded to form cristae structures. Inside is a matrix with enzymes in that are involved in respiration. Aerobic respiration happens here where ATP is produced.
7 of 9
Centriole Description and Function
Small, hollow, cylinders made of microtubules. Involved with the separation of chromosomes during cell division.
8 of 9
Different Ribosomes make Different Proteins
Ribosomes on the RER make proteins that attach to the cell membrane. Free ribosomes make proteins that stay in the cytoplasm.
