Honors Bio Cells/Organelles 2024-2025

Characteristics of prokaryotes

Single celled, has a cell wall, small

Characteristics of Eukaryotes

Contains a nucleus, has mitochondria, bigger,

Characteristics of both Eukaryotes and Prokaryotes

Has cell membrane, has cytoplasm, has ribosomes

Plasma membrane function

Provides protection for the cell

Nucleus function

Stores generic material (DNA) and directs its activity

Mitochondria function

Produces energy in the form of ATP

Golgi apparatus function

Packages and processes proteins and lipid molecules

Cell wall function

Separates the interior contents of the cell from the exterior environment

Ribosome function

Builds protein cells

Why is it a good thing that the cell membrane is permeable

Because it allows the cell to control what substances can enter and exit

Facilitated Diffusion

Passive transport, high to low

Protein pumps/Active trasport

Active transport, low to high
