2.2 Functions Of Cells

Question 1

Name the three main parts of a cell

Answer 1

Cell membrane
Cytoplasm
And nucleus

Question 2

define cell membrane

Answer 2

It is a thin but tough wall surrounding the cell

Question 3

function of cell membrane

Answer 3

Helps transport materials in and out of the cell

It separates the content of the cell from the out side environment

Question 4

define cytoplasm

Answer 4

It is mainly made up of water with some solid s and it is where the cells organelles are found

Question 5

function of cytoplasm

Answer 5

Give shape to the cell
Keep cells organelles separated from one another

Question 6

Define nucleus

Answer 6

It is the control centre of the cell and contains the genes of the cell

Question 7

function of the nucleus

Answer 7

Responsible for cell division

Controls genes of cell

Question 8

define cell wall

Answer 8

The outermost part of the cell that acts as a protective layer

Question 9

cell wall function

Answer 9

Give rigidity strength and protection against infection

Protects internal content of the cell

Question 10

Difine endoplasmic reticulum

Answer 10

It is another system in the cytoplasm and there are two types of ER, rough ER has ribosomes present and smooth ER doesn’t

Question 11

function of endoplasmic reticulum

Answer 11

Gives support to cytoplasm

Helps with transportation inside the cell

Question 12

Define mitochondria

Answer 12

It is a double membrane structure inside the cytoplasm and it is known as the power house of the cell

Question 13

function of mitochondria

Answer 13

Provides energy to the cell

Question 14

Difine ribosomes

Answer 14

There are small practicals mostly found attached to endoplasmic reticulum

Question 15

function of ribosomes

Answer 15

Makes protein in the cell

Question 16

Define golgi complex

Answer 16

Found only in eukaryotic cell and it has its own membrane filled with vesicles

Question 17

function of golgi complex

Answer 17

Produces vacuoles

Makes cell wall , cell membranes

Question 18

Define lysosomes

Answer 18

Tiny sacs filled with fluid containing various enzymes

Question 19

lysosomes functions

Answer 19

Helps with digestion

Question 20

Define vacuoles

Answer 20

There are non living and have membrane on the out side are filled with fluid

Question 21

function of vacuoles

Answer 21

Help the cell maintain pressure

Break down complex molecules

Question 22

Define plastic

Question 23

function of plastids

Question 24

Define centrosomes

Answer 24

There are fund near animal nucleus and consist of two centrioles

Question 25

centrosomes functions

Answer 25

They start and regulate the cell division in animal
