Eukaryotic cell structure
- Microvilli
- Increase surface area
and rate of absorption,
they have enzymes
attached for digestion
- Nucleolus
- Assembles ribosomes within the
nucleus
- Nucleus
- Stores genetic information (DNA) makes
ribosomes in the nucleolus, pores let
ribosomes exit. Contains nucleoplasm,
nuclear pores, chromatin,and a double
nuclear membrane
- Mitochondria
- Carries out respiration, releases energy to let the cell work.
Makes ATP. Has outer membrane and inner membrane called
cristae which is folded for larger surface area. Inside the cell is
called matrix.
- Ribosome
- Site of protein synthesis, transfers through lumen when
made.
- golgi body
- Proteins get transported
via rough endoplasmic
reticulum and are modified.
Then packaged up in a
vesicle and sent on
- Smooth endoplasmic reticulum
- Stores proteins and makes carbohydrates and lipids, doesnt have ribosomes
attached.
- Rough endoplasmic reticulum
- Network of cisternae (flattened membranes) proteins move through this network. ribosomes are
attached
- Lysosomes
- Vesicles with powerful digestive enzymes inside. Digest bacteria, old organelles
and viruses
- Vesicles
- Membrane bound sacs containing various substances,
used for transporting substances from one organelle to
the next or to the cell surface membrane for secretion.
