7th Grade AAP Science Review

Specimen A moves when touched and is found in water. Specimen B makes a noise and is green. Which conclusion is correct?

• Specimen B is living because it is green.

• Specimen B is living because it gets energy from a battery.

• Specimen A is living because it will respond to being touched.

• Specimen A is nonliving because it is found in water.

Which of the following is a characteristic of living things?

• All living things live in water.

• All living things are made up of one or more cells.

• All living things make noises.

• All living things communicate.

Which statement is true of the cell diagrams?

• Model A is an animal cell and model B is a plant cell because model B contains chloroplasts and a cell wall, all of which model A does not have.

• Models A and B are both animal cells because they both contain a nucleus and mitochondria.

• Models A and B are both plant cells because they both contain a nucleus and mitochondria.

• Model A is an animal cell and model B is a plant cell because model A contains a nucleus in the center of the cell and model B contains a nucleus near the edge.

Which student list below shows the correct shows the correct characteristics of living things?

• All living things: eat food for energy, move from place to place, breathe oxygen and have cells

• All living things: eat food for energy, move from place to place, reproduce and have a brain.

• All living things: respond to their environment, reproduce, use energy and adapt/evolve.

• All living things: respond to their environment, reproduce, breathe oxygen and have a nucleus.

A student went to the park and found a round, foreign object laying on the ground. When the student got closer, they noticed the object was breathing. They reached out to touch it, and it rolled away from them. They finally caught the object and took the object home to observe it closer. One week later, the student noticed that the organism had increased in size and was able to make sounds in an effort to communicate with them. Which of the following statements provides valid evidence that the foreign object the student found can be considered a living thing?

• The organism is able to breathe therefore it is considered a living thing because all living things have lungs.

• The organism is able to breathe and therefore would be considered a living thing because all living things breathe oxygen.

• The organism is able to respond to a stimulus and therefore would be considered a living thing because stimuli only affect living things.

• The organism is able to respond to stimulus and therefore would be considered a living thing because a living thing can respond to its environment.

Which of these cell structures are found in both plant and animal cells?

• nucleus, cell wall and mitochondria

• cell membrane, chloroplast, nucleus

• nucleus, vacuole, cell wall

• nucleus, cell membrane, mitochondria

This cell structure controls what enters and leaves the cell.

• Nucleus

• Ribosome

• Mitochondria

• Cell membrane

This cell structure is called the powerhouse of the cell because it's where the energy is released. They are found in both plant and animal cells.

• Nucleus

• Ribosome

• Mitochondria

• Cell membrane

Photosynthesis occurs in this cell structure.

• ribosomes

• Mitochondria

• Chloroplast

• Cell membrane

Which of the following statements is NOT part of the cell theory?

• Cells come from existing cells.

• Cells are the basic units of life

• Plant cells are square and animal cells are round.

• All living things are made of cells..
