Question 6

Virchow

Answer 6

Proved that cells can only come from preexisting cells and came up with cell theory

Question 7

Brown

Answer 7

Named the nucleus

Question 8

Cell Theory

Answer 8

I.All living things are made up of one or more cells
ii. The cell is the basic unit of life
iii. All cells come from preexisting cells

Question 9

Prokaryotic cells

Answer 9

-Simplest and most ancient type of cells
-No Nucleus
-No Membrane bound organelle.
-DNA is in the nucleoid which is in the cytoplasm
-Small cells and cell walls
-Single celled

Question 10

Eukaryotic cells

-Membrane bounded organelle
-More complex
-Have Nucleus
-Single celled or Multicellular

Answer 22

-Eukaryotic
-Makes ATP. (Cellular Energy)

Question 23

Passive Transport

Answer 23

i. No energy required
ii. Molecules move from high concentration to low concentration
iii. Diffusion, osmosis (movement of water), and facilitated diffusion (uses carriers/channel proteins)

Question 24

Answer 24

i. Energy required
ii. Moves molecules from and area of low concentration to high concentration
iii. Bulk transport

Question 25

Endocytosis

Answer 25

Transporting materials inside the cell.

Question 26

Exocytosis
