Eukaryotic cells and organelles

Nucleolus

region within the nucleus where ribosome are made

Nuclear envelope

double membrane which surrounds the nucleus containing pores allowing small molecules to pass into the cytoplasm

Nucleus

contains DNA which controls the activities of the cell

Rough endoplasmic reticulum (RER)

coated with ribosomes- fold and processes proteins that have been made at the ribosomes

Smooth endoplasmic reticulum (SER)

synthesises and processes lipids

Golgi apparatus

made up with a group of fluid-filled membrane-bound flattened sacs - processes and packages new lipids and protein also makes lysosomes

Ribosomes

site where protein is made

mitochondria

site of aerobics respirations where ATP is produced

lysosome

contains digestive enzymes is separated from the rest of the cytoplasm - which engulf and destroys old organelles or foreign material

chloroplasts

site of photosynthesis. it is a small flattened structure found in plant cells its surrounded by a double membrane

Plasma membrane

regulates the movement of substance into and out of the cell- consists of a phospholipids bilayer with additional proteins to serve as carriers

centrioles

involved with the separation of chromosomes during cell divisions

cell wall

made of cellulose- supports plant cell

Flagella

a tail like sturture which is made up of bundles of microtubules- microtubules contract to make the flagellum move

cilia

finger like projections found on the surface of some cells - the microtubules allows the move which is used by the cell to move substance along the cell surface

vacuole

stores cell sap and may also store nutrient and protein
