Prokaryotic Cell
What type of transport requires energy to move molecules?
Active transport
What organisms perform alcoholic fermentation?

Mitosis occurs in what type of cells?
Somatic body cells
What macromolecules makes up the cell membrane?
Lipids (phosolipids)
Name all 3 parts of the cell theory.
1. All living things are made of cells
2. New cells come from pre-existing cells
3. Cells are the basic unit of structure and organization
This type of solution has a lot of solute.
Hypertonic
Chloe watches her dog eat his breakfast and then use his energy from his food to run around the house! What characteristic of life is being described?
Metabolism
What is the role of an enzyme in a chemical reaction?
Speeds up the reaction & lowers the activation energy
This macromolecule has the following elements: CHONP
Nucleic Acid
What is the function of the cell membrane vs the cell wall?
Cell wall: protects and supports the cell
Lionel places red blood cells in a beaker of pure water (hypotonic to the cell), and then he observes their activity under a microscope. What will happen to the cell?
Water diffuses into the red blood cells by osmosis, and the cells eventually burst.
What type of cells will contain BOTH chloroplasts and mitchondiras?
Plant cells!
Lily is developing a model of the eukaryotic cell cycle. The model includes mitosis, in which the chromosomes of a cell separate into single-stranded chromatids. Where should Lily show the duplication of the chromatids to prepare for another round of mitosis?
S phase of the cell cycle
