Module 2 Biology

Which of the following is NOT a characteristic of transport systems in plants and animals?

• A system of vessels in which substances are transported

• A heart to pump the fluid

• A suitable transport medium

• A driving mechanism to move the substances

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

• the negative gravitational pull from Earth.

• the atmospheric pressure on roots.

• osmosis in the roots.

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

Which of the following is NOT a requirement for a successful transpiration stream?

• Adhesion of water cells to the xylem walls

• Cohesive forces between water molecules

• Active transport of water through xylem vessels

• Thick, lignified walls of the xylem tissue to withstand the pressure

Food dye was used in this experiment:

• to dye the water to trace its pathway through the plant.

• to create a pattern in the celery.

• to demonstrate the movement of sugars through the plant.

• to demonstrate that eosin is capable of moving through the plant.

The attraction of water molecules to each other is called:

• adhesion

• cohesion

• attraction

• transpirational pull.

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) only one direction

• (i) transpiration and (ii) only one direction

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

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

Which of the following types of tissue are represented by the diagram below?

• Xylem

• Xylem and phloem

• Vascular bundle

• Phloem

Tags

NGSS.MS-LS2-3

The movement of substances in the phloem is caused by:

• 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 high pressure areas at the source and low pressure areas at the sink.

• 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 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.

• 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.

• (i) a leaf (ii) a growing apple

• (i) the trunk (ii) a leaf

• (i) the roots (ii) a growing shoot

• (i) a growing shoot (ii) a leaf
