Question 1

What are tissues

Answer 1

Group of cells that have the same structure and function and are arranged together to carry out a specific function

Question 2

Examples of tissues in humans

Answer 2

Epithelial, muscle, nerve, connective

Question 3

Where does the epithelial tissues cover?

Answer 3

Covers the outer surface and hollow surfaces in the body

Question 4

What is the function of the epithelial tissues

Answer 4

Adapts based on its function
Protect against infections, injuries, chemicals and dehydration

Question 5

Specific places the epithelial tissues cover

Answer 5

Surface of lungs, mouth, small intestine, blood vessels

Question 6

What are the 3 known types of muscle tissue?

Answer 6

Smooth muscle, skeletal muscle and cardiac muscle

Question 7

Where can the smooth muscle be found?

Answer 7

Blood vessel, reproductive tract, digestive tract

Question 8

Where can the skeletal muscle be found?

Answer 8

Legs and hands

Question 9

Where can the cardiac muscle be found?

Answer 9

Heart wall

Question 10

Function of smooth muscle?

Answer 10

Contraction and relaxation of smooth muscle enables involuntary activities such as peristalsis

Question 11

Function of skeletal muscle?

Answer 11

Contraction and relaxation of skeletal muscle generates movement in bones and limbs (controlled movement)

Question 12

Function of cardiac muscle?

Answer 12

Builds walls of the heart that contract to pump blood to the whole body ( involuntary )

Question 13

What is nerve tissue made of?

Answer 13

Neuron, which consists of a cell body and nerve fibre called dendrite and axon

Question 14

Function of nerve tissues?

Answer 14

Detect stimuli and send information in the form of an electrical signal
Regulates and control body activity

Question 15

Use of connective tissue?

Answer 15

Link organs

Question 16

Types of connective tissue

Answer 16

bone, blood tissue, adipose tissue, cartilage, loose connective tissue, Fibrous connective tissue

Question 17

Function of blood tissue

Answer 17

Plays a role in transportation, protection and regulation

Question 18

Function of bone

Answer 18

Forms the body frame and protects internal organs

Question 19

Function of loose connective tissue

Answer 19

Link epithelial tissue to the tissue below it and fixes organs in position

Question 20

Function of adipose tissue

Answer 20

Keeps fat under the skin dermis and the surface of all main organs

Question 21

Function of cartilage

Answer 21

Encloses bone tips to prevent them from wearing out

Question 22

Function of fibrous connective tissue

Answer 22

Forms tendons and ligaments. Tendons connect muscle and bone while ligaments connect bones to bones

Question 23

What is the function of the parenchyma tissue?

Answer 23

stores starch, protein and water
Can carry out photosynthesis

Question 24

What is the function of the collenchyma tissue?

Answer 24

Functions in giving support to the young, non-woody stems

Question 25

What is the function of the sclerenchyma tissue?

Answer 25

Providing support and mechanical strength to all mature parts of the plant

Question 26

What are vascular tissues made up of

Answer 26

Xylem tissue and phloem tissue

Question 27

Function of xylem tissue

Answer 27

Transports water and mineral salts from the roots to other parts of the plant

Question 28

Function of phloem tissue

Answer 28

Transports organic matter such as sucrose from the leaves the other parts of the plants

Question 29

What cell component is found in abundance in pancreatic cell and goblet cell and what is it use?

Answer 29

Golgi apparatus and rough endoplasmic reticulum. Increase synthesis and secretion of digestive enzymes and produce mucus

Question 30

What cell component is found in abundance in the liver and what is its use?

Answer 30

Smooth endoplasmic reticulum, metabolizes carbohydrates and carries out detoxification of drugs/poisons
