Q

What is passive transport?

A

When a substance moves across the cell membrane down a concentration gradient from a high concentration of one substance to a low concentration of another. Passive transport does not require energy

16
Q

What is osmosis

A

Osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration through a selectively permeable membrane

17
Q

What is the function of the nucleus

A

Contains chromosomes which are made form Dna. These hold genetic information which controls all cell activities

18
Q

What is the function of a cell membrane

A

It’s selectively permeable and controls the entry and exit of material in and out of the cell. Made of phospholipids and protein

19
Q

Cytoplasm

A

Site of chemical reactions

20
Q

Mitochondrion

A

Site of aerobic respiration (more in high energy cell like muscles)

21
Q

Ribosomes

A

Site of protein synthesis

22
Q

Chloroplast

A

Site of photosynthesis contains chlorophyll

23
Q

Vacuole

A

Contains cell sap is important in maintaining shape of the cell

24
Q

Cell wall

A

Gives the cell shape and support

Made of cellulose

25
