Homeostasis Test Questions with Answers
Cell Wall - Ans -Made of cellulose. Found in plant cells. Provides structure, support
and protection for the plant cell.
Plasma membrane - Ans -It controls what can come into the cell, as well as what can
leave the cell. Aids in homeostasis.
Vacuole - Ans -Store food, water, and waste products for the plant cell.
Homeostatsis - Ans -The process of maintaining a stable internal environment.
Buffer - Ans -Chemicals that balance pH.
pH - Ans -Measure of how acidic/basic something is.
Active transport - Ans -Moving materials into and out of the cell, while using energy.
Moving from low concentration to high concentration.
Passive transport - Ans -Moving materials into and out of the cell, without using
energy. Moving from an area of high concentration to low concentration.
Diffusion - Ans -Movement of molecules from an area of higher concentration to an
area of lower concentration.
Osmosis - Ans -Diffusion of water across a selectively permeable membrane. A type
1
of passive transport.
