True or False: For a seed to germinate, it must receive an adequate amount of water.
True
False
Explanation
The statement "For a seed to germinate, it must receive an adequate amount of water." is true. The seed is a small part of a plant and contains the embryo, a tiny new plant. If this seed has the right conditions, including an adequate amount of water, it will germinate, and a new plant will sprout. Without water, the seed will not grow, and no new plants will form.
The saguaro cactus has adapted in numerous ways to protect the water that it collects during rare rainstorms in the desert. It has a vast root system that allows the plant to absorb water near the surface during rainfall. It also has thorns that deter thirsty animals from getting inside the stem of the cactus and drinking its water. The saguaro cactus also has a very thick, barrel-shaped stem used for holding water. Plants that are adapted to these dry places like the saguaro cactus, are called xerophytes. They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.
Which claim below does this passage support?
All plants, even cacti, need water to survive and will adapt new ways to find and keep it.
Some plants need water. The cactus has adapted to like without water and only requires a tiny amount.
Water is an important resource for plants that live in desert environments. Plants in areas of rainfall do not depend on water.
None of these claims are supported by the passage.
Explanation
The claim that is supported by the passage is "All plants, even cacti, need water to survive and will adapt new ways to find and keep it.". The saguaro cactus has a vast root system, a thick stem, and thorns. These adaptations allow the cactus to survive in an environment of very little water which is an essential resource for all plants. The cactus has methods of retrieving water, storing it, and protecting it.

Plants must have water to grow. What structure of the plant absorbs water?
Leaves
Roots
Stem
Flower
Explanation
Humans and animals take in water by drinking it with their mouths. Plants need water but do not have the same structures or parts as humans and animals. The roots of a plant absorb moisture from the soil to hydrate the plant. If the roots are damaged and cannot absorb water, the plant will not survive.

Explanation
This passage described the adaptations of the saguaro cactus. The cactus lives in desert environments, which have very little rainfall. The piece of text evidence from the selection that best supports the idea that the saguaro cactus needs water to survive is, "They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.". This excerpt states that to grow and flourish, the cactus must collect, store, and conserve large amounts of water. This means that water is a vital resource for the plant, and it must have it to survive.

True or False: Plants need air, light, carbon dioxide, and water to grow.
True
False
Explanation
The statement "Plants need air, light, carbon dioxide, and water to grow." is true. Plants need light from the sun to complete photosynthesis and water to stay hydrated and use in creating their food. They need oxygen for respiration, and they absorb carbon dioxide from the air for the transformation into oxygen, sugar, and carbohydrates. All of these things are necessary for their survival.
