Exam 3: Adaptations to Terrestrial Environments

A plant with a high number of stomata

The specialized organelles used in photosynthesis are called

Which is an adaptation to manage cold in extremities?

Photosynthesis primarily allows plants to gain

Root cell adaptation to prevent the cell solutes from equilibrating with the water in the soil include I. semipermeable membranes that prevent the transfer of large molecules. II. cell membranes that can prevent the transfer of water out of the cell. III. cell membranes that can actively transport ions across the gradient.

One factor that drives the movement of water from roots to leaves is

At what water potential does wilting begin to occur?

Why are stomata necessary? What benefit do they provide, and how?

In which soil would the percent water be the highest at the wilting point?

The Calvin cycle in CAM photosynthesis occurs in

An organism that does not maintain a constant body temperature is a(n)

The potential energy generated by the attractive forces between water molecules and soil particles is

Which organ is responsible for removing salts from mammals?

In which soil types would a CAM pathway plant have an advantage over a C₃ pathway plant? Explain why.

The primary source of heat on Earth is

How does fur affect heat transfer?

Explain why the C₄ pathway accounts for a high proportion of photosynthesis worldwide and why this is unexpected.

An organism's ability to maintain constant internal conditions in the face of a varying external environment is called

Wind causes heat transfer by

Why does limited water increase an organism's effort to maintain homeostasis?
