Example Question #5 : Life Science

Plants survive by using their _________ to absorb water. We use a __________ to drink water.

Possible Answers:

stem; bones

leaves; arms

roots; straw

Correct answer:

roots; straw

Explanation:

Plants use their roots to absorb water from the ground to help them survive. Humans also need water to survive and a way we mimic (or copy) the way a plant solves this problem is by using a straw. We use a straw to drink water to help us live.

Example Question #6 : Life Science

The leaves of a water lily float on top of the water because they have a flat bottom. How can we mimic (or copy) plants to float on water?

Possible Answers:

Humans cannot float

Use a raft

Use our leaves

Correct answer:

Use a raft

Explanation:

Humans can copy water lilies and use a raft to float on the surface of the water. The leaves of a water lily float on the surface of the water with their flat bottoms so they can absorb sunlight. We can also float on top of the water but we do not have leaves like plants do.

Example Question #7 : Life Science

What external structures do plants have that help them survive?

Possible Answers:

Roots, stems, leaves, and flowers.

Feet, stems, arms, and flowers.

Roots, bones, hands, and flowers.

Correct answer:

Roots, stems, leaves, and flowers.

Explanation:

Plants have external structures used for survival. Roots are used to absorb water, the stem keeps a plant upright, leaves are used to absorb sunlight and carbon dioxide to make food, and the flowers are used for pollination.

Example Question #8 : Life Science

What is a human problem that can be solved by copying how plants survive?

Possible Answers:

Bicycle helmets are hard just like the shell of an acorn.

Bicycle helmets are pretty just like flowers.

Bicycle helmets are worn on top of the head just like plants grow above the ground.

Correct answer:

Bicycle helmets are hard just like the shell of an acorn.

Explanation:

One human problem that can be solved by mimicking (copying) plants is how we protect our heads on a bicycle. The shells of nuts like the acorn are hard and protect what is inside. Helmets are made to be hard and shaped like our heads to protect us if we fall.

Example Question #9 : Life Science

The thorns on a rose bush help keep predators away. Humans _______ plants and use barbed wire to keep predators away from livestock.

Possible Answers:

water

mimic

kill

Correct answer:

mimic

Explanation:

Humans often mimic plants to solve problems in their everyday life. Livestock such as goats or pigs are prey animals and can be eaten if not protected. The thorns on a rose bush will poke or cut something trying to eat it or climb up it. Barbed wire fences will cut or stick something that tries to climb in or out of the pasture.

Example Question #10 : Life Science

What does it mean to mimic someone or something?

Possible Answers:

To copy

To fight

To be friendly

Correct answer:

To copy

Explanation:

To mimic someone or something means to copy or act the same as. Little brothers and sisters like to mimic or copy older siblings to annoy them! Humans also mimic plants and animals to solve problems.

Example Question #1 : Solve A Human Problem Mimicking How Plants Survive

Humans mimic plants to solve our problems.

Possible Answers:

False

True

Correct answer:

True

Explanation:

This is a true statement. Humans look at how plants use their external parts to survive and copy those features to help us in our own lives.

Example Question #2 : Solve A Human Problem Mimicking How Plants Survive

How are plants useful to humans besides food?

Possible Answers:

Humans cannot use plants for anything besides food.

Humans can mimic plants for survival.

Humans can use plants to tell the future.

Correct answer:

Humans can mimic plants for survival.

Explanation:

Plants are useful to humans because they are able to mimic or copy their structures for survival. We can copy their thorns or the way they float and use that information to make ways for us to do the same things.

Example Question #3 : Solve A Human Problem Mimicking How Plants Survive

The foundation of a house keeps it stable and in place. What part of the plant does the same?

Possible Answers:

Roots

Leaves

Flower

Correct answer:

Roots

Explanation:

The roots of a plant keep it stable and in place. Humans have mimicked or copied this survival strategy and used it to keep our houses in place and stable. Without strong roots or a strong foundation the plant or home would fall over.

Example Question #4 : Solve A Human Problem Mimicking How Plants Survive

There are no parts of a plant that are similar to something a human uses.

Possible Answers:

True

False

Correct answer:

False

Explanation:

There are many parts of a plant that humans use to solve their own problems and make new items. Rafts, helmets, fencing, and more are all modeled after plant parts.
