Structure of cells

Question 1

animal cells have…

Answer 1

a cell membrane, a nucleus, cytoplasm and a nucleolus

Question 2

plant cells have…

Answer 2

a cell wall, chloroplasts, cytoplasm, a cell membrane, a vacuole, a nucleus and nucleolus

Question 3

there are differences between plant and animal cells, which are they?

Answer 3

plants have a cellulose wall, a permanent shape (determined by the cell wall), chloroplasts, and a large permanent vacuole in cytoplasm containing cell sap. animals do not have any of these, except for the shapes that vary since there is no cell wall and a vacuole, which is small and does not contain cell sap.

what they do have in common is that they both have a cell membrane, a nucleus and cytoplasm

Question 4

what are the functions of the cell membrane?

Answer 4

.forms barrier between cell and surroundings
.keeps contents of cell inside
.allows simple substances to enter and leave the cell
.controls movement of other substances into and out of cell
.partially permeable

Question 5

what are the functions of the nucleus?

Answer 5

.controls all activities in cells

.controls how cells develop

Question 6

what is the function of the cytoplasm?

Answer 6

.place where many chemical reactions take place

Question 7

what are the functions of the chloroplast?

Answer 7

.photosynthesis

.stores starch

Question 8

what are the functions of the cell wall?

Answer 8

.stops cells from bursting when they fill with water
.gives shape to cells
.allows water and dissolved substances to pass through freely (fully permeable)

Question 9

what are the functions of the sap vacuole?

Answer 9

.full of water to maintain shape and ‘firmness’ of cell

.stores salts and sugars

Question 10

cells of organisms classified as prokaryote kingdom contain which of the following?

a-cell membrane, enzymes, nucleus, vesicles
b-cell wall, cell membrane, cytoplasm, ribosomes
c-cytoplasm, DNA, endoplasmic reticulum, ribosomes
d-cytoplasm, DNA, enzymes, mitochondria

Answer 10

b-cell wall, cell membrane, cytoplasm, ribosomes

Question 11

which is not found in an animal cell?

a-nucleus
b-permanent vacuole
c-ribosomes
d-rough endoplasmic vacuole

Answer 11

b-permanent vacuole

Question 12

which structure is not found in animal cells?

a-cell membrane
b-cell wall
c-cytoplasm
d-nucleus

Answer 12

b-cell wall

Question 13

which structure is found only in plant cells?

a-cell membrane
b-chloroplast
c-cytoplasm
d-nucleus

Answer 13

b-chloroplast
