Adaptations of Plants in Different Habitats

Plants that live in salt marshes absorb a lot of salt water. What adaptation do these plants most likely have?

• They have spines on their leaves.

• They depend on rain for water.

• They have stiff stems for support in water.

• They have a way to get excess salt out of their bodies.

An adaptation that helps a cactus live in the desert is its

• wide, flat leaves to catch water

• bright green color

• thin, spiny needles

• tall stems

Which of the following adaptations best​ explains how pine trees are able to prevent water loss or damage from freezing temperatures?

• Pine trees have thick bark

• Pine cones produce seeds.

• Pine tree roots go deep underground.

• Pine needles are thin and have a wax coating.

In a dense forest, some trees are very tall. The type of plant MOST LIKELY to survive underneath these trees is one that

• can store water.

• produce many seeds

• needs little sunlight.

• can withstand the cold.

Mr. Walker plants a new plant next to a tall tree in his yard. It is partly in the sun, but is mostly in the shade. He notices that it is growing with all of its leaves on one side. Why is the plant growing this way?

• It is trying to get sunlight.

• It is trying to stay in the shade.

• It wants to be closer to the tree.

Why does a cactus have shallow roots while other desert plants have deeper roots?

• Shallow roots help to absorb water quickly before it evaporates.

• A cactus does not need deep roots because it has a strong stem.

• Other plants only want to take in water that is deep underground.

• The water near the surface is much better for helping a cactus to grow.

Which adaptation allows mangrove trees to survive in coastal environments with high salt levels?

• Aerial roots for oxygen intake

• Thick bark to prevent water loss

• Salt-excreting leaves

• Deep roots for stability

How do desert plants like succulents minimize water loss?

• By having broad leaves

• By opening stomata at night

• By growing tall to reach sunlight

• By having shallow roots

What is the primary reason for the waxy coating on the leaves of rainforest plants?

• To attract pollinators

• To prevent water loss

• To increase photosynthesis

• To deter herbivores
