Green algae are more closely related to land plants than to other algae.
True
The primary function of vascular tissue in plants is to store carbohydrates.
False
Stomata help reduce water loss in plants by closing when water is scarce.
True
Gymnosperms reproduce using flowers and fruits.
False
Land plants play a major role in the carbon cycle by removing CO₂ from the atmosphere.
True
Xylem transports water and nutrients upward, while phloem distributes sugars throughout the plant.
True
A plant’s cuticle helps prevent water loss.
True
Mosses are nonvascular plants that rely on water for reproduction.
True
All plants exhibit indeterminate growth, meaning they grow continuously throughout their life.
False
Ferns, like mosses, do not have vascular tissue.
False
A plant growing in nutrient-poor soil is likely to have an extensive root system.
True
An increase in atmospheric CO₂ is likely to enhance primary production in plants.
True
Homeostasis refers to an organism’s ability to maintain a stable internal environment.
True
Acclimatization is a long-term evolutionary change, while adaptation is a short-term response to environmental conditions.
False
Small animals have a higher mass-specific metabolic rate than large animals.
True
Countercurrent heat exchange helps organisms conserve heat in cold environments.
True
Endotherms regulate their body temperature primarily through metabolic heat production.
True
All poikilotherms are also ectotherms.
True
Negative feedback mechanisms are essential for maintaining homeostasis.
True
Evaporation is a major way animals lose heat in hot environments.
True
Which of the following is NOT an adaptation that allowed plants to survive on land?
c) Photosynthesis
Which plant group does NOT produce seeds?
c) Ferns
The major function of phloem in plants is to:
b) Transport sugars
Which statement best describes a fitness trade-off?
a) An organism with a high metabolic rate also has a high energy requirement.
