Question 4

function of Golgi bodies

Answer 4

stores, modifies and packages proteins

Question 5

structure of Golgi bodies

Answer 5

a stack of flat membrane sacs linked to the endoplasmic reticulum

Question 6

function of lysosome

Answer 6

membrane bound vesicles that obtain enzymes used to break down foreign material

Question 7

structure of lysosomes

Answer 7

a sac bounded by a single membrane, pinched off from the Golgi apparatus. contains enzymes and sometimes fragments of material being broken down

Question 8

structure of mitochondria

Answer 8

composed of folded layers of double layer membrane,

Question 9

function of mitochondria

Answer 9

involved in cellular respiration, they are the site that ATP is created as they transform energy

Question 10

function and structure of nucleus

Answer 10

it contains DNA material (chromosomes) and controls the activities of cells

Question 11

function of ribosomes

Answer 11

they are the site that proteins are assembled and manufactured

Question 12

structure of ribosomes

Answer 12

located either free in the cytoplasm or associated with the endoplasmic reticulum surface

Question 13

function and structure of the vacuole

Answer 13

membrane bound organelles (larger in plants) they store and control growth and the moving if different materials

Question 14

cell walls are found in which organisms, and serve which purpose?

Answer 14

cellulose structure outside the cell membrane of plants only that helps to give support

Question 15

cytoplasm function and structure

Answer 15

all the space in between other organelles in a cell, the site of translation in the cell

Question 16

function and structure of the cytoskeleton

Answer 16

network of fibres in the cytoplasm that supports the cell

Question 17

cell membrane structure and function

Answer 17

a bilayer of phospholipids, encloses the cytoplasm and controls movement in and out of the cell

Question 18

function and structure of centrioles

Answer 18

a pair of small cylindrical structures composed of microtubes that are involved in separating chromosomes during mitosis
