Structures Functions

This woodpecker has a hard, pointed beak. For what purpose is its beak best adapted?

• Scooping fish from the water

• Digging insects out of tree bark

• Cracking large nuts and seeds

• Collecting nectar from flowers

Some plants, such as a cactus, are covered with sharp spines. How do these structures help the cactus survive?

• They protect the cactus from animals that eat it

• They let the cactus get water from the ground.

• They allow food to pass into the cactus stem.

• They provide shade and shelter for the cactus.

Students observed cells under the microscope. They observed that the cells had a cell wall, cell membrane, nucleus, and many chloroplasts. Which observation helps students identify the type of cell observed?

• The presence of a nucleus means the cells are from a plant.

• The presence of a cell membrane means that the cells are from an animal.

• The presence of chloroplasts means that the cells are from a plant.

• The presence of a cell wall means that the cells are from an animal.
