Multiple Choice
What kind of macromolecule holds genetic info?
Nucleic Acids
Cell membrane
Flexible covering that protects the inside of a cell from the environment outside of a cell.
Cell theory
The cell theory is 3 statements saying "All living organisms are made up of one or more cells", "A cell is the basic unit of life", and "New cells come from preexisting cells".
Nucleus
Part of a eukaryotic cells that directs cell activities and contains genetic info stored in DNA.
Relate how animals get the energy plants store during photosynthesis.
Animals get their energy plants store during photosynthesis by eating plants.
What organelles does a plant cell have that an animal cell doesn't?
Cell wall, chloroplasts
Handles storage, waste management, and maintaining fluid or pressure balance.
Explain the role of chloroplasts in photosynthesis.
The role of chloroplasts in photosynthesis is to convert light energy into chemical energy through photosynthesis.
Active transport
The movement of substances through a cell membrane only by using the cell's energy.
Identify how cellular respiration, fermentation, and oxygen are used by our cells to make energy when we exercise.
During exercise, your cells use a combination of cellular respiration and fermentation to break down glucose and generate ATP.
The diffusion of water molecules only through a cell membrane.
Facilitated Diffusion
When molecules pass through a cell membrane's using special proteins called transport proteins.
Compare endocytosis with exocytosis.
They both are active transport processes that require energy to move large molecules across the plasma membrane, but they move materials in opposite directions.
