Animal cells

Cell membrane

regulates what goes in and out. Also has receptor molecules which allow it to respond to chemicals

Nuclear envelope

double membrane surrounding the nucleus separating it from the cytoplasm and protecting the DNA

Nuclear pores

protein lined envelope that regulates passage of molecules between nucleus and cytoplasm

Chromatin

a mixture of  DNA and proteins that makes up chromosomes

Nucleolus

made up of RNA and proteins and is where ribosomes are made

Lysosome

contains digestive enzymes that digest invading enzymes or break down old components of the cell

Ribosomes

can float free or be attached to the rough endoplasmic reticulum. It’s made up of proteins and RNA and makes proteins

Rough endoplasmic reticulum

fluid surrounded by membranes that are covered with ribosomes. It folds and processes proteins that have been made in the ribosomes.

Smooth endoplasmic recticulum

Unlike the RER it has no ribosomes. It synthesis and processes lipids

Vesicle

a fluid sac in the cytoplasm that transports substances in and out the cell and between organelles.

Golgi apparatus

group of flattened sacs that process and package new lipids and proteins. It also makes lysosomes

Cilia

hair like structures on the cell membrane. It has a membrane with nine pairs of rings on the outside and two pairs on the inside(known as 9+2)

Centrioles

micro tubules involved with separation of chromosomes during cell division
