Unit 5: Cell Theory, Types of Cells, and Cell Organelles BTA

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 (prokaryotes and eukaryotes)?

• cell membrane and cytoplasm

• chloroplasts and mitochondria

• a cell wall and nucleus

• chloroplasts and cell wall

Which cell structure is found in plant and animals cells and controls what can come into or leave a cell?

• cell membrane
• cytoplasm
• nucleus
• vacuole

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

Cell organelles that are responsible for digesting food, worn out organelles and other cellular wastes are called ___________________.

• Mitochondria
• Vacuoles
• Lysosomes
• Chlororplasts

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

What is the function of a cell wall?

• to protect and support the cell
• to perform different functions in each cell
• to prevent water from passing through it
• to prevent oxygen from entering the cell

In what part of the plant cell does the process of photosynthesis take place?

• nucleus
• mitochondria
• chloroplasts
• vacuoles
