Cell Unit Review

Evelyn and Luna are having a debate. Can you help them out? What term describes the smallest unit that can perform all the functions necessary for life?

• a single cell

• a cell nucleus

• a cell membrane

• a multicellular organism

Benjamin and Abigail are discussing how molecules move. Can you help them figure out which process describes the movement of molecules from an area of higher concentration to an area of lower concentration (without a semipermeable membrane)?

• active transport

• diffusion

• osmosis

• photosynthesis

Imagine you're a tiny water droplet on an adventure through a cell wall! What process are you experiencing as you move from a solution with low solute concentration to one with high solute concentration?

• Diffusion

• Equilibrium

• Metabolism

• Osmosis

During a lively science class, Harper and Anika are debating: What process describes the movement of substances through the cell membrane without the input of energy?

• active transport

• equilibrium

• passive transport

• photosynthesis

Imagine you're in a science class with Mason, Hannah, and Scarlett. The teacher asks, 'What process occurs when energy is needed to move materials through a cell membrane?'

• active transport

• equilibrium

• metabolism

• passive transport

Imagine you're a tiny explorer like Lily or David, venturing through the human body! Which of these paths shows the journey from the simplest to the most complex level of organization?

• muscle cell, muscle tissue, muscle, muscular system

• muscle tissue, muscle cell, muscle, muscular system

• muscle, muscle tissue, muscular system, muscle cell

• muscular system, muscle, muscle tissue, muscle cell

Imagine you're in a science class with James, Abigail, and Noah. What is the condition called when two areas have the same number of molecules, making them perfectly balanced?

• cellular respiration

• equilibrium

• metabolism

• osmosis

Hey Rohan and Scarlett, can you guess what plants whip up using carbon dioxide, water, and a sprinkle of sunlight magic?

• energy

• chlorophyll

• carbon monoxide

• glucose and oxygen

In a lively classroom debate, Kai, Rohan, and Arjun are discussing how organisms get the energy they need. Can you help them figure it out?

• Plants get energy from fertilizers, and animals get energy by drinking water.

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

• Plants do not require energy because they do not move, and animals get energy by performing exercise.

• Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.

Imagine you're a tiny molecule on an adventure! You're hanging out near a cell with your friends, Grace, Anika, and Maya. How will you and your molecule buddies move as a result of diffusion?

• into the cell

• out of the cell

• into another cell

• to the external environment
