Q

What did Louis Pasteur do?

A

He disproved the idea of spontaneous generation by doing the chicken broth experiment. It showed that when the chicken was warm it didn’t absorb bacteria, but when it was cold it absorbed bacteria.

Q

Nucleolus:

A

Controls the cell’s activities just like the brain controls human actions.

17
Q

Chloroplasts:

A

Contains chlorophyll which produces the green color: sites of photosynthesis.

18
Q

Vacuole:

A

Membrane-bound structures that serve to store nutrients, and fats, depending on the tissue type.

19
Q

Rough Endoplasmic Reticulum:

A

Produces protein for the rest of the cell to function.

20
Q

Smooth Endoplasmic Reticulum:

A

It doesn’t have ribsomes which means it doesn’t make protein for the cell, but produces lipids.

21
Q

Ribosome:

A

Help amino acids to link together to produce protein.

22
Q

Lysasome:

A

Membrane-bound cells which causes digestion to go on.

23
Q

Golgi Body

A

Prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell

24
Q

Mitochondria:

A

Make most of the energy for the cell. Energy production.

25
Q

Centrioles:

A

Organize microtubules that serve as the cell’s skeletal system.

26
Q

4 Major types of organic compounds:

A

Lipids, carbohydrates, proteins and nucleic acids

27
Q

Chemical elements found in cells:

A

Carbon, hydrogen, oxygen, and nitrogen

28
Q

Trace elements (tiny amounts found in a cell):

A

Zinc, manganese, magnesium, and iron

29
Q

Similiraties in a plant and animal cell:

A
  • Both have a cell membrane.
  • Both have genetic material (DNA)
30
Q

Differences between plant and animal cells:

A
  • The vacuole of an animal cell is smaller than the vacuole of a plant cell.
  • An animal cell has only a cell membrane, while a plant cell has a cell wall AND a cell membrane. An animal cell doesn’t have a cell wall.
  • The plant cell has chloroplasts, but the animal cell doesn’t.
