- - Contents called nucleoplasm
- - Controls cell through DNA
- - Directs protein synthesis and cell division
- - Surrounded by double membrane
- - Contains nucleolus (composed of proteins, DNA, RNA, produces ribosomes)
- - Network of membrane bound cisternae
- - Smoothe ER: synthesis of lipids, steroids- transport materials in and between cells
- - Deoxifies drugs and some metabolites
- - Rough ER: ribosomes on membrane surface
- - involved in synthesis of proteins.
- - Transport of proteins in cisternae
- - Bound by double membrane
- - Inner membrane folded into cisternae, increases surface area for attachment of enzymes.
- - Membranes enclose a matrix
- - cisternae and matrix provide different sites for various stages of aerobic respiriation and production of ATP
- - Contain mitochondrial DNA and ribosomes which control enzyme production and allow replication
- Receives enzymes, proteins, lipids, glycoproteins synthesised in ER
- Encloses them into membranes, releases into cytoplasm or outside cell.
- Spherical sac containing digestive enzymes
- Fuse with vacuoles, enhance digestion
- Breaks down unwanted cell contents
- Can completely break down damaged cells
- Set of 2 cylindrical bodies adjacent to the nucleus
- Involved in flagella and cilia formation
- Cell division in animals
- Sometimes found in algae
