B3 and B4 IB Biology review

What is vital capacity?

• The amount of air inhaled after maximal exhalation

• The amount of air exhaled after minimal inhalation

• The amount of air exhaled after maximal inhalation

• The amount of air inhaled during maximal inhalation

Answer explanation

Spirometry: A tool to measure lung vital capacity. Vital Capacity: Greatest volume of air expelled from the lungs after taking the deepest breath possible, 4-6 Liters in healthy adults. Output for Spirometry = spirogram.

(a)   is a form of a pulmonary function test. It is helpful in measuring lung function

Answer explanation

Spirometry: A tool to measure lung vital capacity. Vital Capacity: Greatest volume of air expelled from the lungs after taking the deepest breath possible, 4-6 Liters in healthy adults. Output for Spirometry = spirogram.

The diagnostic tool to measure changes in lung volume creates which analysis output?

• Spirogram

• Vital Capacity

• Spirometry

• Flow-volume graph

• Functional Residual Capacity

Answer explanation

Spirometry: A tool to measure lung vital capacity. Vital Capacity: Greatest volume of air expelled from the lungs after taking the deepest breath possible, 4-6 Liters in healthy adults. Output for Spirometry = spirogram

What is the main function of xylem tissue?

• Storing water and nutrients

• Producing energy for the plant

• Transporting water and nutrients

• Protecting the plant from pathogens

Which tissue is responsible for the transport of water in plants?

• phloem

• epidermis

• xylem

• mesophyll

What is the process called when water moves from the roots to the leaves through xylem?

• osmosis

• respiration

• photosynthesis

• transpiration

Which tissue is responsible for the transport of sugars and other organic compounds in plants?

• xylem

• phloem

• epidermis

• mesophyll

What is the process called when sugars move from the leaves to other parts of the plant through phloem?

• respiration

• photosynthesis

• translocation

• transpiration

What is the major difference between xylem and phloem?

• Xylem transports sugars and organic compounds, while phloem transports water and minerals.

• Xylem and phloem have the same function of transporting sugars and organic compounds.

• Xylem transports water and minerals, while phloem transports sugars and organic compounds.

• Xylem and phloem both transport water and minerals.

Vascular tissue locations...

• Stem: on the outside, Roots: central

• Stem: central, Roots: on the outside

• same locations for both stem and roots

• vascular tissue is actually absent in the roots

Answer explanation

• Vascular tissue (xylem and phloem) in the stem is closer to the outer edge, xylem to the inside and phloem to the outside and cambium in the middle.

• Roots are a little different: Vascular tissue in the root is closer to the center of the root.
