Multiple Choice

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall

Multiple Choice

True or False? Passive Transport does not require energy

• true

• false

Multiple Choice

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

Cells in a hypertonic solution will shrivel up as they dehydrate from loss of water. There is MORE dissolved substance OUTSIDE the cell than inside!

Hypertonic Solution

Cells in an isotonic solution will maintain their size. They are HAPPY! There is the SAME amount of dissolved substance both INSIDE and OUTSIDE the cell.

Isotonic Solution

Cells in a hypotonic solution will swell up and can burst! There is LESS dissolved substance OUTSIDE the cell than inside!

Hypotonic Solution

Multiple Choice

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Match

Match the following

• Hypertonic Solution

• Hypotonic Solution

• Isotonic Solution

• Passive Transport

• Active Transport

Multiple Choice

Which is true about active transport?

Multiple Choice

Where does photosynthesis happen in a plant?

• In the chloroplasts inside the cells of the leaves.

• In the Golgi Apparatus inside the cells of the roots.

• In the Nucleus inside the cells of the flowers.

Multiple Choice

What green pigment is inside the chloroplasts?

• Chlorine

• Chloride

• Chloroform

• Chlorophyll

Multiple Choice

Make a prediction: Where does the carbon dioxide produced in photosynthesis go?

• The carbon dioxide is released back into the atmosphere immediately.
• The carbon dioxide is stored in the soil for later use.
• The carbon dioxide is converted into oxygen during respiration.
• The carbon dioxide is used to produce ATP in the process of Cellular Respiration.

Multiple Choice

What is the DESIRED end product of Cellular Respiration?

• Carbon Dioxide
• Oxygen
• ATP (adenosine triphosphate)
• Glucose

Multiple Choice

What are the two WASTE products of Cellular Respiration?

• Lactic acid and ethanol
• Nitrogen and sulfur
• Carbon dioxide and water
• Oxygen and glucose

Multiple Choice

What is the purpose of cellular respiration?

• To use the energy (glucose) made in photosynthesis.

• To convert oxygen to CO2.

• To make vitamins for the cell to use.

Multiple Choice

How do photosynthesis and cellular respiration work together?

• Photosynthesis produces glucose and oxygen, which are used in cellular respiration to generate energy, carbon dioxide, and water, forming a cycle.
• Photosynthesis consumes carbon dioxide and releases nitrogen, which is used in cellular respiration.
• Photosynthesis and cellular respiration are completely unrelated processes that do not interact.
• Cellular respiration occurs only in plants, while photosynthesis occurs in animals.
