Which macromolecule contains genetic information?
Nucleic acids
100
What structure is not found in an animal cell but is found in a plant cell?
Cell wall
100
What process does water go through to travel through a membrane?
Osmosis
100
This stores food, water and waste materials in a cell?
vacuole
200
What directs all cell activity?
Nucleus
200
The movement of substances using transport proteins (Does not use energy)
facilitated diffusion
200
Movement of substances using the cell's energy?
active transport
200
movement of substances into a cell by surrounding them with the cell membrane?
endocytosis
300
What type of macromolecule is sugar?
carbohydrate
300
How does water move during osmosis?
from areas of high concentration to areas of low concentration
300
This structure protects the organelles in all cells.
Cell membrane
300
Through what process does a cell membrane engulf substances?
endocytosis
400
How do animals get energy stored by plants made from sunlight?
Animals eat plants and then use a process called cellular respiration to obtain the energy the plants stored in their tissues during photosynthesis. During cellular respiration, food molecules are broken down and the energy in them is released

Describe the cell theory
- All living things comes from 1 or more cells -The cell is the smallest unit of life -All new cells come from preexisting cells

Describe a difference of a plant and animal cell.
Plant cells have cell walls, and animal cells do not. Plant cells have chloroplasts that animal cells do not have. Plant cells also have a large central vacuole that animal cells lack.
400
Of the four scientists that help develop the cell theory, explain what two of them did.
Robert Hooke used a microscope to make one of the earliest observations of cells. Matthias Schleiden and Theodor Schwann observed that plant and animal cells have similar structures. Rudolf Virchow proposed that all cells come from preexisting cells
