Conifers that do not lose their leaves every year can begin photosynthesis very early in the spring when plants without leaves are still dormant. The conifer can use available resources to survive rather than to produce new leaves. In what conditions does this adaptation allow conifers to survive?

• wet and cold conditions

• hot and humid tropical conditions

• nutrient poor soil conditions

• cold and dry tundra conditions found above the timberline

Why are dispersal adaptations in the seeds of flowering plants important to their survival?

• They protect seeds against drought

• They prevent the seeds from being eaten by other organisms

• They increase competition between parent and offspring

• They allow seeds to be carried away from the parent plant

A flowering plant seed that is covered in curved barbs is probably dispersed by which method?

• wind

• the feces of animals

• hitching a ride in fur

• propulsion from the parent plant

How might prop roots be MOST helpful in corn plants?

• to absorb oxygen from the air

• to keep the plants upright in the wind

• to obtain water deep in the soil

• to conduct photosynthesis

Which of the following adaptations would you MOST expect to see on a plant that lives in a hot, dry desert climate?

• large, flat leaves

• prop roots

• shallow roots that remain close to the plant

• small leaves with few stomata

• dark-colored flowers with little scent

• small, dome-shaped flowers

• flowers that smell like rotten meat

A plant giving off phenols prevents other plants from growing nearby. How does this adaptation increase the plant's chances of survival?

• It makes it easier to pollinate the flowers

• It does not have to share resources such as water with other plants

• It decreases the chances of predators eating the leaves

• It will be easier to disperse its seeds
