Cell as Basic Unit of Life

Which of the following is the smallest unit of life that can carry out all life functions?

• the mitochondria
• the vacuoles
• the nucleus
• the cell

Which structures are found in every living cell?

• cell membrane and cytoplasm
• chloroplasts and mitochondria
• a cell wall and nucleus
• chloroplasts and cell wall

What is the function of the cell nucleus found in both plant and animal cells?

• to produce energy
• to control cell activity
• to remove waste products
• to allow molecules to enter the cell

What is one basic function of the vacuoles?

• circulating oxygen
• producing food
• controlling cell processes
• storing water

Chloroplasts in plant cells allow the plant to perform a function that animal cells cannot do.  What is the main function of the chloroplasts found in plant cells?

• to absorb light energy and manufacture food
• to remove waste materials by active transport
• to manufacture chemical energy from food
• to control the shape of the cell

All cells need energy to function.  Which cell organelle is responsible for producing energy in the cell?

• chloroplasts
• mitochondria
• nucleus
• vacuoles

Cells with a nucleus and membrane-bound organelles are called ____________________.

• prokaryotes
• eukaryotes
• bacteria
• protists

What is the function of this organelle?

• Sac that stores water, nutrients, and waste products

• Regulates what enters and leaves the cell

• Structures that transport and ship proteins like UPS

• Cite of cellular respiration also known as the powerhouse of the cell

What is the function of this part of the cell?

• Structure

• Flexability

• Regulates what comes in and out of the cell

• Stores genetic information

Which best explains the relationship between chloroplasts and mitochondria?

• Chlorplasts absorb light energy from the sun, which is converted to glucose by the mitochondria. 
• Chloroplasts produce carbon dioxide and water, which are used by the mitochondria to produce energy. 
• Chloroplasts store energy in the chemical bonds of glucose, which is used by the mitochondria to produce ATP.
• Chloroplasts release light energy stored in the glucose in the form of ATP, which is absorbed by mitochondria.
