cell structure and organelles

Question 1

the organelle that is the control centre. it coordinates all of the cells activities

Answer 1

nucleus

Question 2

the organelle that stores and packs molecules like proteins and fats in vesicles ready for transport

Answer 2

Golgi apparatus

Question 3

the organelle that stores and packs molecules like proteins and fats in vesicles ready for transport

Answer 3

Golgi apparatus

Question 4

the organelle that is the site of chemical respiration. it produces adenosine triphosphate

Answer 4

mitochondria

Question 5

the organelle that produces and stores lipids and steroids

Answer 5

smooth endoplasmic reticulum

Question 6

the organelle that contains ribosomes and produces and stores proteins

Answer 6

lysosomes

Question 7

a vesicles that contain enzymes and digest waste products and debris in the cell

Answer 7

rough endoplasmic reticulum

Question 8

the organelle that stirs the cells RNA. it produces ribosomes

Answer 8

nucleolus

Question 9

the organelle that are conventional lysosomes but contain secretory products like hormones

Answer 9

secretory lysosomes

Question 10

a phospholipid bilayer that is embedded with proteins and other bio molecules. it encloses the cell

Answer 10

plasma membrane

Question 11

hair like projections that move fluid over the cells surface

Answer 11

cilia

Question 12

hollow cylinders arranged at right angles from each other. they are important in spindle formation in cell division

Answer 12

centrioles

Question 13

organelles that are found in the cytoplasm and embedded in the rough er that manufacture proteins

Answer 13

ribosomes

Question 14

the organelle that maintains the cells shape. made of microtubules, actin filaments and intermediate filaments

Answer 14

cytoskeleton

Question 15

small membrane bound vesicles that contain oxidative enzymes. they help to remove toxic waste

Answer 15

peroxisomes

Question 16

gel like substance that contains the cells contents. chemical reactions take place here

Answer 16

cytoplasm

Question 17

component of the plasma membrane that are the main component that forms a bilayer. that have a head that contains water and a tail that repels it. it controls what goes in and out of the cell

Answer 17

phospholipid

Question 18

component of the plasma membrane that it temporarily attached and transfer enzymes and molecules

Answer 18

peripheral protein

Question 19

components of the plasma membrane that are permanently embedded. they chanel and support molecules

Answer 19

integral proteins

Question 20

components of the plasma membrane that are permanently embedded. they chanel and support molecules

Answer 20

integral proteins

Question 21

the component of the plasma membrane that maintains structural integrity. it regulates fluidity

Answer 21

cholesterol

Question 22

the component of the plasma membrane that recognises other cells as foreign or familiar and help cells attach to other cells

Answer 22

glycoproteins

Question 23

what are the roles of the plasma membrane?

Answer 23

provides protection for the cell, provides a fixed environment, allows nutrients to be transported into the cell and toxic substances out of the cell, isolates cytoplasm from external environment
