Q

What is the difference between a eukaryotic cell and prokaryotic cell

A

Prokaryotes:
- No nucleus
- Unicellular
- No membrane-bound organelles
- Smaller
- Simpler

Eukaryotes:
- Contains a nucleus
- Multicellular or unicellular
- Contain organelles
- Newer, larger, more complex

40
Q

Isotonic solution

A

EQUAL
Equal solute (salt) - equal water

41
Q

Hypotonic solution

A

Inside: higher solute (more salt, less water)
Higher water concentration outside
Water enters the cell
Hypo -> “hippo” -> swells

42
Q

Hypertonic solution

A

Inside: higher water concentration (more water, less salt)
Higher water inside
Water diffuses out of the cell
Shrinks
