Life Science 3.3 Practice

Charlotte, Emma, and James were discussing human biology. Emma said, 'Humans like us are',

• systems.

• organisms.

• protists.

Mia, Sophia, and Anika are observing different living things in their biology class. Can you help them classify every living thing they observe? Is it a(n)

• system

• organism

• animal

Imagine Scarlett, Mason, and Oliver are biologists studying the behavior of large animals like elephants and whales. One advantage these large animals have compared to smaller organisms is that they have...

• larger cells.

• fewer predators.

• simpler functions.

Sophia, Michael, and Arjun are studying the benefits of multicellular organisms. Which of the following is NOT a benefit of multicellular organisms compared to unicellular organisms?

• Their life is dependent on one cell

• They can specialize in different tasks

• They have fewer predators

Emma, James, and Elijah are discussing the life span of a tree, a multicellular organism. They come up with different ideas. Which of the following statements is correct?

• The life span of a tree is only as long as the life of one leaf.

• The life span of a tree is shorter than that of a single-celled organism.

• The life span of a tree is not limited to the life of a single leaf.

Imagine Emma, Aria, and Zoe are studying a pet dog. They are curious about what could significantly alter its life span. Can you help them pick the correct choice?

• Less than 10 hairs fall out during the same day

• 100 hairs fall out from several different parts of its body

• Over a million (1,000,000) hairs fall out from the same small area

Kai, Michael, and Abigail are studying biology. They are examining a slice of onion under a microscope and notice a group of cells that seem to be performing the same function. What does this group of cells make up?

• an organ system.

• a tissue.

• a structure.

Kai, Liam, and Maya are studying for their biology test. They come across a chapter that explains how several organs working together form a(n)...

• tissue

• organ system

• organism

Scarlett, Anika, and Aiden are on a field trip to a botanical garden. They come across a beautiful plant and Anika wonders, 'In which type of tissue does this plant perform photosynthesis?'

• nerve tissue

• muscle tissue

• ground tissue

Ethan, Abigail, and Olivia are learning about plant cells in their biology class. They've discovered that chloroplasts perform photosynthesis. Can you help them figure out the name of the tissue where this exciting process takes place?

• bone

• nerve

• ground
