Biology Test

Question 1

Organs and tissues

Order and descriptions

Answer 1

Tissue -> organ -> organ system

Tissue is made up of one or more types of cells

Organs are made up of one or more type of tissue

Organ systems are made up of multiple different organs

Question 2

Muscular system

Answer 2

Consists of layers of muscle covering the skeleton and joints

Contract and relax to produce movement

Question 3

Skeletal system

Answer 3

Strong flexible network of bones and connective tissue

Provides support for the body and protection for internal organs

Question 4

Circulatory system

Answer 4

Heart and network of blood vessels that carry blood vessels that carry blood

Supplies nutrients and removes wastes from the body’s cells

Question 5

Nervous system

Answer 5

Brain, spinal cord and network of nerves

The body’s control system

Question 6

Respiratory system

Answer 6

Gas exchange

Provides a surface to exchange oxygen for carbon dioxide (waste)

Pathway
The tubes leading to the lungs

Question 7

Digestive system

Answer 7

The group of organs that break down food and absorb the nutrients used by the body for fuels

Takes in food, digest it, absorbs nutrients, eliminates wastes

Question 8

Types of tissues

Answer 8

Epithelial tissue

Connective tissue

Muscle tissue

Nerve tissue

Question 9

Epithelial tissue

Example
Description
And function

Answer 9

Eg) skin, lining of digestive system, cheek cells

Description: thin sheets of tightly packed cells covering surfaces and lining internal organs

Functions: protein from dehydration, low friction surfaces

Question 10

Connective tissue

Example
Description
And function

Answer 10

Example: bone, tendons, blood*, fat tissue

Description: various types of cells and fibres held together by a liquid, solid, or gas known as matrix

Function: support, Insulation

Question 11

Muscle tissue

Example
Description
And function

Answer 11

Example: muscles

• skeletal: moves bones voluntarily
• cardiac: heart, involuntary
• smooth: organs, involuntary

Description: bundles of long cells called muscle fibres that contain specialized proteins capable shortening or contracting

Function: movement

Question 12

Nerve tissue

Example
Description
And function

Answer 12

Example: brain, nerves in sensory organs

Description: long thin cells with fine branches. Capable of conductive electrical impulses

Function: communicate within the body, sensory, coordinations of body functions

Question 16

Contents of blood

Answer 16

Blood is a connective tissue
4 components:
Red blood cells
- erythrocytes
Function: transport oxygen
White blood cells
- leukocytes 
- lymphocytes
Function: fight infection 
Platelets
- thrombocytes
Function: help in blood clotting
Plasma
Function: protein rich liquid that carries the blood cells along

Question 17

Main parts of circulatory system

Answer 17

• blood
• heart
• blood vessels

Question 18

Blood vessels

Answer 18

Arteries - carry blood AWAY from heart

Capillaries - tiny blood vessels with thin walls that allow diffusion to occur( connect arterie to vein)

Veins - carry blood to heart

Question 19

Substances transported by circulatory system

Answer 19

Nutrients
Oxygen
Carbon dioxide
Other wastes
Hormones
Etc

Question 20

Systems in flowering plants

Answer 20

Shoot system
Includes stem, leaves, flower, and fruit
Conducts photosynthesis(leaves) and sexual reproduction( flowers)
Some leaves are adapted for support, protection, reproduction, and attraction
Flowers contain male or female of both reproductive structures
Eggs are fertilized by pollen to produce seeds, usually contained inside a fruit
Pollination can occur with the help of wind, or animals
Stem supports other plant parts and transports materials

Root system - usually found underground
Absorbs water and minerals from soil and store food
Useful source of foods, flavouring, fibres, and natural remedies

Question 21

Plant tissue systems

Answer 21

Dermal tissue - forms outer surface of plant parts

• epidermal tissue
• periderm

Vascular tissue - cells specialized for transport

• xylem
• phloem

Ground tissue - makes up other structures
Performs photosynthesis, storage

More detail wb pg 190

Question 22

Xylem vs phloem

Answer 22

Xylem
- one way only
- water and minerals
- no end walls between cells
- thick walls stiffened with lignin
- dead cells
Phloem
- water and food
- cells have end walls with perforations
- two way flow
- living
