The main driving force for the movement of water from the roots to the top of the plant is:

the tension caused by the evaporation of water through the stomata.

the negative gravitational pull from Earth.

the atmospheric pressure on roots.

The term given to (i) the movement of the products of photosynthesis throughout the plant and (ii) the direction of movement is:

(i) translocation and (ii) whichever direction is required

(i) translocation and (ii) only one direction

(i) transpiration and (ii) only one direction

(i) transpiration and (ii) whichever direction is required

The movement of substances in the phloem is caused by:

the formation of high pressure areas at the source and low pressure areas at the sink.

the formation of high pressure areas at the sink and low pressure areas at the source.

the movement of water in the xylem.

the formation of equal areas of pressure at both the source and the sink.

Which of the following best describes how a region of high pressure is formed in the phloem tissue?

Water moves by osmosis into the phloem tissue, which creates a dilute solution, which in turn causes sugars to be actively pumped into the phloem.

Water is actively pumped into the phloem tissue, which creates a dilute solution, which in turn causes sugars to move by diffusion into the phloem.

Sugars are actively pumped into the phloem tissue, which creates a concentrated solution, which in turn causes water to move by osmosis into the phloem.

Sugars move by diffusion into the phloem tissue, which creates a concentrated solution, which in turn causes water to be actively pumped into the phloem.

Invertebrate animals possess an open circulatory system. An open circulatory system does NOT:

transport gases through the body of the organism.

possess open-ended blood vessels

surround the organs with blood.

The component that makes up the greatest percentage in human blood is:

red and white blood cells combined

As blood circulates from the heart through the body, it changes colour. Which of the following statements is correct?

Blood turns dark red because the amount of oxygen in it decreases.

Blood turns light red because the amount of oxygen it is carrying decreases.

Blood turns dark red because it is picking up oxygen.

Blood turns light red because it is picking up oxygen.

What is the main function of the leaf?

To absorb sunlight and carry out photosynthesis

The leaves of plants are adapted to absorb the maximum amount of sunlight possible. Which of the following options is NOT an adaptation of the leaf to absorb the maximum amount of sunlight?

Cuticle covering the upper and lower surface of the leaf

Palisade mesophyll cells packed with chloroplasts

Vertical, elongated palisade cells

In an experiment, two leaves were taken from the same plant and examined under a light microscope. In leaf 1 most of the stomata were closed; in leaf 2, most of the stomata were open. What is the most likely explanation for this difference?

Leaf 1 was removed when the plant was water stressed; leaf 2 was removed when the plant was not water stressed.

Leaf 1 was removed when the plant was still growing; leaf 2 was removed when the plant was mature.

Leaf 1 was removed on a cold day; leaf 2 was removed on a very hot day.

Leaf 1 was removed during the day; leaf 2 was removed at night.

The alveoli situated within the lungs is the gaseous exchange surface in mammals. Which of the following is NOT a characteristic that would ensure efficient gas exchange?

A small number of capillaries surround each alveolus.

The large number of small alveoli provides a large surface area.

Each alveolus has a single layer of flattened cells.

The surface of all parts of the respiratory system is moist.

What is the main function of the respiratory system?

to provide oxygen and remove carbon dioxide from the body

to break down food and absorb nutrients

to remove oxygen from the body and deliver carbon dioxide

Which of the following is not a primary function of blood?

transports nutrients, oxygen, wastes, and hormones

Wolves have sharp teeth used for

cutting through skin and drinking blood

Horses have wide, flat teeth used for

cutting through skin and drinking blood

What is true about fish?

Fish have gills that take in oxygen.

Fish have mouths that take in air

Fish can breathe during digestion.

Fish can breathe using their hearts.

Stomach chambering cows and related animals in which symbiotic bacteria digest cellulose into usable protein.

Ability to eat both plants and animals.

Digestive chamber with a single opening.
