Chapter 7.2

Question 1

Nucleolus

Answer 1

• Inside the nucleus
• Plays a part in cell division

Question 2

Nucleus

Answer 2

• Contains DNA (genetic material)
• The control center of the cell (like the brain)

Question 3

Nuclear envelope

Answer 3

• The membrane that surrounds the nucleus
• It is porous so it let’s certain things go in and out nucleus

Question 4

Rough endoplasmic reticulum (E.R.)

Answer 4

• Series of canals that help transport proteins with cell
• Coverd with ribosomes (protein synthesis)

Question 5

Centrioles

Answer 5

• Involved in cell division
• Move chromosomes to where they need to go
• Always 2 of them

Question 6

Mitochondrion

Answer 6

• The “power house” of the cell
• Converts glucose (sugar) into energy that the cell can use

Question 7

Golgi apparatus

Answer 7

• “Packages” proteins (and other substances) to be transported (and protected) to where it needs to go

Question 8

Ribosome (attached)

Answer 8

• Involved in protein synthesis
• Attached to the Encloplasmic Reticulum (E.R.)

Question 9

Cell membrane

Answer 9

• Protects the cell and holds it together
• Is semi-permeable: only allows certain things in and out of the cell

Question 10

Ribosomes (free)

Answer 10

• Involved in protein synthesis (and other thing… maybe?)
• They are free inside of the cell

Question 11

Smooth endoplasmic reticulum (E.R)

Answer 11

• Transportation system
• Without ribosomes

Question 12

Cytoplasm

Answer 12

• Protects the organelles and hold them in place
• It fills the cell

Question 13

Cell wall (only plants cell have)

Answer 13

• Rigid outer layer that surrounds the cell membrane
• Extra layer of protection

Question 14

Chloroplast (only plants cell have)

Answer 14

• Where photosynthesis takes place
• Process that converts light energy into energy that cells can use

Question 15

Vacuole (only plants cell have)

Answer 15

• Stores water and other nutrients

Question 16

The levels of organization in a multicellular organism

Answer 16

• Cells
• Tissues
• Organs
• Organ Systems

Question 17

Cells

Answer 17

• Basic units of life
• E.g. mucle cell

Question 18

Tissues

Answer 18

• Similar cells that perform a particular function
• E.g. mucle tissue

Question 19

Organs

Answer 19

• Similar tissues that works together
• E.g. heart

Question 20

Organ Systems

Answer 20

• A group of organs that work together to perform a task
• E.g. circulatory system (heart arteries/ veins blood)
