eukaryotic and prokaryotic cell functions

Question 1

which cells are often eukaryotic

Answer 1

animal and plant cells

Question 2

what do all eukaryotic cells have

Answer 2

all eukaryotic cells have a cell membrane, cytoplasm and nucleus containing dna

Question 3

which cells are prokaryotic

Answer 3

bacterial cells are prokaryotic cells

Question 4

what do prokaryotic cells have

Answer 4

cell walls, cell membrane, cytoplasm and a single circular strand of dna and plasmids

Question 5

what is the difference in eukaryotic and prokaryotic in size

Answer 5

prokaryotic cells are much smaller

Question 6

what is the difference in prokaryotic and eukaryotic in reference to their internal structures

Answer 6

prokaryotic cells do not have a nucleus while eukaryotic cells do have ah nucleus

Question 7

what are the structures within a cell called

Answer 7

the structured within a cell are called organelles

Question 8

what are organelles

Answer 8

organelles are structures in a cell that have different specific functions

Question 9

what is the function of a nucleus

Answer 9

a nucleus contains dna coding for a particular protein needed to build new cells and is enclosed in a nucleus membrane

Question 10

what is the function of cytoplasm

Answer 10

cytoplasm is a liquid substance in which chemical reactions occur.

Question 11

what does cytoplasm contain

Answer 11

cytoplasm contains enzymes (biological catalysts)

Question 12

what are enzymes

Answer 12

enzymes are biological catalysts, proteins that speed up the rate of reaction

Question 13

what is found within the cytoplasm

Answer 13

organelles are found within the cytoplasm

Question 14

what is the function of the cell membrane

Answer 14

the cell membrane controls what enters and leaves the cell

Question 15

what is the function of mitochondria

Answer 15

mitochondria is where aerobic respiration reactions occur which in turn provides energy for the cell

Question 16

what is the function of ribosomes

Answer 16

ribosomes are where proteinsythesis occurs

Question 17

where are ribosomes found

Answer 17

ribosomes are found on a structure called the rough endoplasmic reticulum

Question 18

what three organelles are only present in plant cells and not animal cells?

Answer 18

chloroplasts, permanent vacuole and a cell wall

Question 19

what is the function of chloroplasts

Answer 19

chloroplasts are where photosynthesis takes places, providing food for the plant

Question 20

why are leaves green

Answer 20

within the plant cell, chloroplasts contain chlorophyll pigment which makes it green

Question 21

what is the function of chlorophyll

Answer 21

chlorophyll harvests the light needed for photosynthesis

Question 22

what is the function of a permanent vacuole

Answer 22

a permanent vacuole contains cell sap and is found within the cytoplasm to improve the cell’s rigidity

Question 23

what is the function of a cell wall

Answer 23

cell walls provide strength to the cell

Question 24

what is the difference in the cell wall of a plant and that of a bacterial cell

Answer 24

a plant cell wall is made of cellulose while a bacterial cell wall is made from peptidoglycan

Question 25

what is the function of chromosomal dna

Answer 25

as bacterial cells don’t have a nucleus, the genetic material floats in the cytoplasm

Question 26

what is the function of plasmids

Answer 26

plasmids are small rings of dna which provide code fr extra genes to those provided by chromosomal dna

Question 27

what is the function of a flagella

Answer 27

flagella are long, thin ‘whip-like’ tails attached to bacteria that allow them to move
