Answer 6

Sites for protein manufacture.

Question 7

What is the function of the Endoplasmic Reticulum?

Answer 7

• Surface for chemical reaction
• Transport of materials within the cell

Question 8

What is the function of the Golgi Body?

Answer 8

• Concentrates, stores and packages the materials for secretion from the cell.

Question 9

What is the function of the Lysosomes?

Answer 9

Digest material within the cell.

Question 10

What is the function of the Mitochondria?

Answer 10

Make energy available for cell activities.

Question 11

What is the function of the Cilla and Flagella?

Answer 11

Moves particles along the Cell surface or moves the cell.

Question 12

What is the function of the Cytoskeleton?

Answer 12

Maintains cell shape, allows the cell and its organelles to move.

Question 13

What is the function of the Inclusions?

Answer 13

Chemical substances used by, or stored in, the cell.

Question 14

Structure of the body?

Answer 14

Cells > tissues > organs > systems

Question 15

what are cells broken up into?

Answer 15

Individual units;

• Specialised
• Unspecialised

Question 16

what types of tissues are there?

Answer 16

• Muscle; involuntary, voluntary.
• Bone; skeletal.
• Nerve
• Epithelial
• Connective

Question 17

What is epithelial tissue?

Answer 17

A covering or lining tissues. Eg: the lining of the stomach, the pouter layer for the skin.

Question 18

What is connective tissue?

Answer 18

Provides support for the body, helps to hold all the body parts together. Eg: Bones, cartilage, tendons ligaments etc.

Question 19

what is muscular tissue?

Answer 19

• Longsrrands, muscle fibres; Eg. - skeletal, smooth and cardiac muscle.

Question 20

What is involuntary muscle?

Answer 20

• No conscious control; Eg- iris, blood, heart, uterus, wall of stomach.

Question 21

What is nervous tissue?

Answer 21

Nervous tissue is the main tissue component of the two parts of the nervous system; the brain and spinal cord.
Eg. 
- specialised cells
- neurons 
- spinal cord 
- brain

intake of oxygen and removal of carbon dioxide.

Question 24

Function of the circulatory system?

Answer 24

transport of nutrients, oxygen and wastes to and from the cells.

Question 25

Function of the nervous system?

Answer 25

detection of changes in the environment and porodingation of the body activities.

Question 26

Function of the skeletal?

Answer 26

regulation and coordination of many body functions.

Question 27

Function of the muscular system?

Answer 27

support of/and protection for body parts.

Question 28

What is exocytosis?

Answer 28

contents of a vesicle are pushed out through a cell membrane.

Question 29

What is endocytosis?

Answer 29

form of active transport in which a cell transports molecules.

Question 30

what is active transport?

Answer 30

when a higher concentration moves across the membrane to the lower form of concentration to balance it.
