Question 3

Prokaryotes

Answer 3

No nucleus/ membrane bound organelles, smaller and simpler than eukaryotes, mostly unicellular.

Question 4

Eukaryotes

Answer 4

Cell with a nucleus and membrane bound organelles, larger and much more complex than prokaryotes, mostly multicellular.

Answer 7

All animals are composed of cells (swan).

Question 8

Rudolf Virchow

Answer 8

All cells come from existing cells. (Cows come from cows).

Question 9

A (traditional cell theory 1)

Answer 9

All organisms are made up of cells.

Question 10

B (traditional cell theory 2)

Answer 10

Cells are the basic unit of structure + function.

Question 11

C (traditional cell theory 3)

Answer 11

Cells come from pre-existing cells.

Question 12

D (modern cell theory 1)

Answer 12

Cells contain hereditary information. (DNA).

Question 13

E (modern cell theory 2)

Answer 13

Energy Flow occurs within cells.

Question 14

F (modern cell theory 3)

Answer 14

All cells are basically the same on chemical composition + metabolic functions.

Question 15

Difference between rough and smooth ER.

Answer 15

Smooth- Makes lipids.
Rough- Covered with ribosomes which make proteins
Same- Transports molecules.

Question 16

If ribosomes aren’t functioning in a cell, what happens and why?

Answer 16

Protein synthesis stops and the cell eventually dies. Because they catalyze reactions.

Question 17

How do you calculate total magnification?

Answer 17

Objective power x Eyepiece power.
