Answers

Question 1

Cell > Tissue > Organ > Organ system > Organism

 

Question 2

Xylem Phloem
Material Transports water and minerals Transports sugars
Movement Unidirectional movement (from roots to shoots) Bidirectional movement
Transport Passive transport Passive and active transport
Theory Transpiration-adhesion-cohesion-tension (TACT) theory Pressure-flow hypothesis / source to sink

 

Question 3

(d) All of the above

 

Question 4

Examples include red kangaroo.

Dentition:

Prominent incisors for the initial cutting of vegetation. Lacks canine teeth but has large flat molars and premolars for the breakdown of the tough cellulose found in grass.

Digestive tract:

Long and complex. Has a caecum for the fermentation of cellulose by gut microorganisms.

 

Question 5

Unicellular organisms such as bacteria are made up of one cell. The cell can carry out all the necessary functions in the organism.

Multicellular organisms such as animals and plants consist of many specialised cells that work together to perform different tasks in the body. The cells cannot survive on their own if separated.

Colonial organisms such as Pandorina refer to a colony of single-celled organisms living together. The cells in the colony can survive on their own if separated.

 

Question 6

  1. Rich blood supply for the rapid transport of gases around the body.
  2. Large surface area to maximise diffusion rate.
  3. Thin and moist membranes to allow gases to easily diffuse across membranes and into the blood.

 

Question 7

Oxygen-18

 

Question 8

Structure Function
Mouth
  • Breaks food down mechanically with the help of teeth.
  • Breaks down food chemically with the help of enzymes in saliva.
  • Mechanical breakdown of food increases the surface area of food allowing enzymes to act on it.
Stomach
  • Breaks down food chemically by secreting hydrochloric acid and pepsin enzyme.
  • Mechanical breakdown of food through contraction of the stomach increases surface area in contact with acid and pepsin enzyme.
Small intestine
  • Absorption of nutrients from food facilitated by internal projections called villi that increase surface area for an optimum absorption.
Large intestine
  •  Absorption of water and vitamins.
Rectum and anus
  • Stores waste products of digestion (faeces) until eliminated from the body through the anus.

 

Question 9

Open circulatory systems

  • Have open-ended vessels that are filled with blood-like fluid called haemolymph.
  • The haemolymph is pumped by a simple tube heart into the body cavity.
  • Haemolymph flows directly over organs.
  • Exchange of nutrients and wastes occurs when cells and tissues interact with the haemolymph.
  • Haemolymph does NOT transport gases.
  • This system is mostly seen in invertebrates such as insects.

 

Closed circulatory systems

  • A heart pumps blood containing gases, nutrients and wastes around the body through closed vessels.
  • Arteries carry oxygenated blood away from the heart.
  • Veins carry de-oxygenated blood from the body back to the heart.
  • Capillaries connect veins and arteries together. This is where nutrient and waste exchange occur.
  • This system is mostly seen in vertebrates such as mammals.

 

Question 10

(c) Oxygen enters the blood while Carbon dioxide leaves the blood.
