Eukaryotic is larger! Prokaryotic is smaller

Question 7

(P vs. E) which includes plants, animals, and fungi?

Answer 7

Eukaryotic! Includes Eukarya (plants, animals, and fungi) Prokaryotic includes bacteria and archaea

Question 8

(P vs. E) one type is where most have cell walls, the other is where some have cells walls. which is which?

Answer 9

Prokaryotic: most have cell walls
Eukaryotic: some have cells walls

Question 10

which out of animal and plant cells have centrioles? What is a centriole?

Answer 10

Animal cells! A centriole is an organelle that helps cells divide. (make copies of themselves)

Question 11

Which out of plants and animals cells have cell walls?
What are cell walls?

Answer 11

Plant cells! Cell walls: have a rigid frame to provide strength and support

Question 12

Which between animal and plant cells have chloroplasts?

Answer 12

Plant cells! Chloroplasts are the site of photosynthesis

Question 13

Which between Plant and Animal cells have larger water vacuoles?

Answer 13

Plant cells! Both have vacuoles however plant cells have larger ones than animal cells

Question 14

Define an organelle

Answer 14

little organs that control special activities of the cell

Question 15

What is the Cytoplasm?

Answer 15

a gel-like substance that suspends organelles and contains nutrients needed for the cell

Question 16

what is a vacuole? vesicles?

Answer 16

vacuoles are membrane bound sacs that hold materials. Vesicles are typically smaller

Question 17

What is the job of the Endoplasmic Reticulum? Rough Endoplasmic Reticulum?
Smooth Reticulum?

Answer 17

what are their jobs? produces, processes, and transports. Types: RER: has ribosomes (gives rough appearance) SR: smooth appearance, produces fats and oils.

Question 18

what are ribosomes?

Answer 18

makes proteins, can be free or attached

Question 19

What are Lysosomes?

Answer 19

specialized vesicle that contains an enzyme that breaks down (“digests”) materials like bacteria and damaged organelles

Question 20

What is the Golgi Apparatus?
(Golgi Body)

Answer 20

packages materials produced by the cell

Question 21

What is a Mitochondria?

Answer 21

site for cellular respiration (cells derive energy from glucose), makes the energy used by the cell

Question 22

What is the Nucleus?

Answer 22

area that controls DNA, directs cellular activity

Question 23

What are Nuclear Pores?

Answer 23

allows movement of materials in and out of nucleus

Question 24

what is a nucleolus?

Answer 24

controls the nucleus

Question 25

what is the nuclear membrane?
(nuclear envelope)

Answer 25

acts as a barrier

Question 26

What is a Nucleoplasm?

Answer 26

gel-like solvent inside nucleus

Question 27

What is the Cell Membrane?

Answer 27

acts as a barrier and control what enters and leaves a cell
