Basic Cell Study

Question 1

Cell Membrane “Gate”

Answer 1

• Protects cell

- Allows things (water and nutrients) to move in and out of the cell

Question 2

Cell Wall

Answer 2

• Plants only
• Protective barrier for plants
• Maintains cell shape

Question 3

Chloroplast

Answer 3

• Plants only
• Contains chlorophyll (green pigment)
• Used in plant “digestion”

Question 4

Chromosome

Answer 4

Thin strands within the nucleus of the cell

Question 5

Cytoplasm

Answer 5

Everything in the cell except cell membrane and nucleus and nucleus (thick liquid and organelles)

Question 6

Dehydration

Answer 6

Happens when cells lose more water than they take in

Question 7

Diffusion

Answer 7

The movement of materials from an area with a lot of the material to an area with less of the material

Question 8

Golgi Apparatus “manufacturing plant”

Answer 8

Packages things needed in the cell and gets them ready for transport elsewhere

Question 9

Lysosome “garbage disposal”

Answer 9

• Helps digest food
• Break down invading organisms, cells when they die
• Could cause cell death if not monitored

Question 10

Mitochondria “power house”

Answer 10

Provides the cell with energy

Question 11

Nucleus “brain”

Answer 11

• Communicates with the cell

- Holds DNA

Question 12

Organelles

Answer 12

Any cell structure with a specific job to do

Question 13

Osmosis

Answer 13

Diffusion of water through a cell membrane

Question 14

Endoplasmic Reticulum

Answer 14

• Combines proteins
• Packages proteins
• Exports proteins

Question 15

Ribosome

Answer 15

Builds proteins

Question 16

Vacuole “vacuum”

Answer 16

Storage (water, nutrients, etc.)

Question 17

Which are only found in plant cells?

Answer 17

• Cell wall

- Chloroplast

Question 18

What organelle is only found in animal cells?

Answer 18

Centriole

Question 19

What are all three parts of the cell theory?

Answer 19

1. All living things are made up of cells
2. Cells are the basic unit of life
3. Cells can only come from other cells

Question 20

True or False: Even though all cells have similar parts, they can have different jobs (functions) or shapes?

Answer 20

True

Question 21

Who was the first person to use the term cell?

Answer 21

Robert Hooke

Question 22

In what material was the first cell discovered in?

Answer 22

Cork

Question 23

What are the thin strands found in the nucleus of the cell, that contain instruction for the cell?

Answer 23

Chromatins

Question 24

What process is the movement of materials from an area with a lot of material to an area with less material?

Answer 24

Diffusion

Question 25

What is the diffusion of water through a cell membrane called?

Answer 25

Osmosis

Question 26

What happens when you water a wilted plant?

Answer 26

When you water a wilted plant, it absorbs the water because it hasn’t had any water. The process osmosis gathers the water in one place and puts it in the cells that have less water.

Question 27

What happens to cells when they lose more water than they take in?

Answer 27

They dehydrate

Question 28

What do you think happens to the cells of your body if you sweat a lot but don’t drink enough water?

Answer 28

The cells dehydrate because you are using the water in your body when your body needs water.
