a plant cell when it swells is
_________ pressure
• turgor
What part of the phospholipid
would be touching water?
• Phosphate head
What is the significance of all
the folds in the mitochondria?
• The folds increase the
surface area so this

Osmosis does not occur when a
cell is placed into a(n) _______
solution
• isotonic
Why does active transport use
cellular energy?
• Active transports moves molecules
from an area of LOW to HIGH
concentration (against the
concentration gradient)
Identify:
• Chloroplast
The first person to observe and
describe microscopic organisms
and living cells was
• Anton Leeuenhoek
What type of active transport is
used to remove wastes and
mucus from a cell?
• Exocytosis

and chloroplast similar?
• Both help make energy
