Chapter 5A

Question 1

Levels of cellular organisation.

Answer 1

Cells, Tissues, Organs, Systems, Organisms

Question 2

specialised cells

Answer 2

Have a specific function to
perform and have structural adaptations to help them carry out their specific role.

e.g.
Animal: Red blood cells, neurons

Plant: root hair, guard cells

Question 2

Tissues

Answer 2

are groups of similar cells working
together to carry out a particular function for the organism.

eg. Muscle tissue, blood, root tissue

Question 2

Organs

Answer 2

consists of two or more tissues that work together to perform specialised tasks.

eg heart, lungs, leaf, roots

Question 3

Systems

Answer 3

Are formed from a group of organs that work together to perform a vital task.

eg. Circulatory system, respiratory system

Transport , shoot and root systems in plants.

Question 4

Vascular plants

Answer 4

Contain vascular tissues that transport
water and minerals, sugars throughout the plant.

Question 4

Non-vascular plants

Answer 4

(like moss) do not contain vascular
tissues and only require simple tissues to function.

Question 4

Xylem cells

Answer 4

Transport of water and minerals from the roots to the leaves of the plant

Question 4

Phloem cells

Answer 4

Transport sugars and nutrients throughout the plant

Question 5

Palisade cells

Answer 5

Cells in a leaf that carry out photosynthesis

Question 6

Sclerenchyma cells

Answer 6

Provide support to the plant

Question 7

Leaves Function

Answer 7

Gaseous exchange occurs here

Photosynthesis takes place

Water is lost by evaporation

Question 7

dermal tissue

Answer 7

cells that form the outer linings of a plant

Question 7

ground tissue

Answer 7

cells that form a number of tissues that are involved in metabolism and support

Question 8

vascular tissue

Answer 8

cells involved with transport around the plant

Question 8

Flowers Function

Answer 8

Sexual reproductive organs. Pollen (male gamete meets the female gamete (eggs) and fertilization occurs)

Seed develops

Fruit grows after fertilization.

Question 9

Fruit Function

Answer 9

Grow from a flower post fertilization

Protect seeds and aid with seed dispersal.

Question 10

Stem Function

Answer 10

Provide support to the plant

Question 11

Roots Function

Answer 11

Absorb water from the soil.

Help anchor plant in ground and provide support.

Question 12

Root System Function

Answer 12

Underground

Absorbs water and nutrients from soil

Provides support & structure

Question 13

Shoot System Function

Answer 13

Reproductive parts: flowers & fruit

Non-reproductive parts: leaves & stems

Question 14

Connective tissue Function

Answer 14

Connects and supports other tissues
and organ structures of the body.

Question 14

Muscle tissue Function

Answer 14

Contracts and relaxes to aid with
movements.

Eg. Skeletal, cardiac and smooth

Question 15

Nervous tissue Function

Answer 15

Detects changes and sends electrical
signals to the CNS

Made up of neural pathways.

Question 15

Epithelial tissue Function

Answer 15

Tissues that assist in protection, secretion and absorption.

Question 16

Digestive system Function

Answer 16

Breaks down and absorbs food to be used by the body.

Question 16

Respiratory system Function

Answer 16

Gaseous exchange of oxygen and carbon dioxide.

Question 17

Endocrine system Function

Answer 17

Responsible for the production and secretion of hormones that regulate body processes.

Question 17

Circulatory system Function

Answer 17

Delivers oxygen and nutrients to the tissues of the body via blood.

Question 17

Immune system Function

Answer 17

Defends the body against infection.

Question 18

Nervous system Function

Answer 18

Detects sensory information in order to activate appropriate responses.
