Describe the cell theory & list 3 generalizations it explains about cells.

Answer 1

Developed by several scientist using the data they gathered over a 200 year period.

1. All living are made up of at least one cell.
2. The cell is the most basic unit of life.
3. All new cells come from existing cells.

Question 2

What are he 3 general areas of a cell

Answer 2

1. Cell membrane
2. Cytoplasm and organelles
3. Nucleus

Question 3

Define eukaryotic and prokaryotic cells

Answer 3

Eukaryotic- contains a nucleus

Prokaryotic- doesn’t contain a nucleus

Question 4

Give some examples of prokaryotic and eukaryotic cells.

Answer 4

Eukaryotic- plant, animal, fungi, protist

Prokaryotic- bacteria and red blood cells.

Question 5

Nucleus

Answer 5

Control center of the cell- acts like a cell membrane

Question 6

Nucleolus

Answer 6

Organelle that makes proteins

Question 7

Ribosomes

Answer 7

Site of protein synthesis– where protein molecules are made using the directions from DNA

Question 8

Mitochondria

Answer 8

Converts the chemical energy stored in food into compounds that are more convenient for the cell to use

Question 9

Rough ER

Answer 9

Contains ribosome on the outside of it’s membrane- serves as a tunnel for molecules to travel through the cytoplasm or out of the cell

Question 10

Smooth ER

Answer 10

Organelle responsible for making new organelle and cell membrane using lipids, carbohydrates and proteins

Question 11

Lysosomes

Answer 11

Breaks down lipids, carbs and proteins into small molecules that can be used by the rest of the cell

Question 12

Vacuole

Answer 12

Stores materials such as water salts proteins and carbs

Question 13

Golgi apparatus

Answer 13

Modifies and stores proteins

Question 14

Cytoplasm

Answer 14

Fluid in between nuclear and cell membrane

Question 15

Name the 2 structures that are on found in plant cells

Answer 15

Cell wall- tough supportive and protective covering of plants
Chloroplast- captures the energy from the sunlight and converts it into chemical energy
