Exam 6: Plant Adaptations to the Environment

Submerged aquatic plants typically have stomata.

Total carbon loss through respiration is a function of the total mass of living tissue.

Overall, water movement from the soil, through plant tissues, and finally to the atmosphere through transpiration is driven by a gradient of

C₄ plants use the enzyme ________ to fix CO₂.

Net CO₂ uptake by a plant is greatest

In the C₃ photosynthetic pathway, the enzyme Rubisco catalyzes the reaction called

The drier the air outside a leaf, the faster water will be lost from the leaf through the stomata.

Drought deciduous plants lose leaves just as the dry season begins.

When resources are plentiful, plants will allocate the most carbon to the production of

Which of the following elements is considered a plant micronutrient?

A plant adapted to a dry, sunny environment might be expected to have

A plant takes in water and loses carbon dioxide through its open stomata.

Describe the differences in carbon acquisition between terrestrial and aquatic plants.

Leaf shape and size influences the thickness and dynamics of the ________ layer and therefore the ability of plants to exchange heat through ________.

All the following are plant adaptations to low temperatures, EXCEPT

Terrestrial plants exchange heat by convection and ________.

Allocation of carbon to roots directly increases both respiration and photosynthesis rates.

Photosynthesis produces more water than it uses.

Photosynthesis transforms oxygen and carbon dioxide into carbohydrates and water.

Leaf area ratio (LAR)is the product of specific leaf area (SLA)and
