THE INTERNAL STRUCTURE OF
PROKARYOTE
- PLASMA
MEMBRANE
- Function
- responsible for controlling what gets into and out of the cell
- Synthesizes cell wall components
- Assists in DNA replication
- Captures energy as ATP
- Carries on respiration
- responsible for controlling what gets into and out of the cell
- structure
- phospholipid bilayer with proteins embedded in and attached
to the intracellular and extracellular surfaces
- often have two plasma membranes with a space between
them known as the periplasm
- phospholipid bilayer with proteins embedded in and attached
to the intracellular and extracellular surfaces
- Function
- CYTOPLASM
- substance of the
cell inside the plasma
membrane
- Gel-like, yet fluid
(80% Water)
- Biologists
discovered that
prokaryotic cells
have a complex and
functional
cytoskeleton, helps
to divide and helps
the cell maintain its
plump, round shape
- substance of the
cell inside the plasma
membrane
- NUCLEOID
(DNA)
- contains the main DNA material
- bacterial chromosome, bacteria often contain small
circular, double-stranded DNA molecules called plasmid
- Plasmic do not contain genetic
material essential for growth (limited)
- contains the main DNA material
- RIBOSOMES
- Protein synthesis
- Have about half of the amount of ribosomal RNA (rRNA)
- Can be inhibited by certain antibiotics
- Protein synthesis
