Eukaryotic and prokaryotic cells

3.2.1

Function of Cell-surface membrane

Regulates the movement of substances into and out of the cell

Function of nucleus

Contains cell’s activity and makes ribosomes

Function of mitochondria

Site of aerobic respiration and produces ATP

Function of chloroplast

Site of photosynthesis

Function of golgi apparatus

Processes and packages lipids and proteins

Function of vesicle

Stores lipids and proteins to transport them out of the cell

Function of Lysosome

Contains digestive enzymes called lysozyme and digest invading cells

Function of ribosome

Site where proteins are made

Function of RER

Synthesises and processes lipids

Function of SER

Synthesised and processes lipids

Function of Cell wall

Supports cell and prevents from changing shape

Function of Vacuole

Maintains pressure in the cell and keeps cell rigid

What are prokaryotes?

Single-celled organisms

DNA of prokaryotes?

Circular and have no histones

Function of Flagellum?

Rotates to make the cell move

Function of Plasmids

small loops of DNA which contains genes

Function of Capsule

Protects the bacteria from attack by the cells of immune system

What glycoprotein is the Cell wall in prokaryotes made from?

Murein

Difference of the prokaryotic ribosomes from the eukaryotic?

Smaller

Viruses are acellular. What does this mean?

Not in cells

What are viruses?

Nucleic acids surrounded by protein

What do viruses have?

Protein coat, capsid and attachment protein

How do viruses attach to the host cell?

Using their attachment proteins to bind to the complementary receptor proteins on the cell-surface membrane
