Cells CFA Worksheet

Which structures carry out life functions within cells?

• organ systems

• organelles

• organs

• tissues

As the basic units of life, cells are living systems that carry out all of the functions needed to sustain life. Which process is common to all cells?

• All cells get nutrients from the air.

• All cells need and use energy.

• All cells make their own food.

• All cells allow organisms to move.

Unlike animal cells, plant cells contain a

• nucleus to perform photosynthesis.

• cellulose-based cytoplasm that makes these cells sturdy.

• cellulose-based cell wall that makes these cells sturdy.

• mitochondrion to perform photosynthesis.

Which best describes how the function of the cell membrane differs in plant and animal cells?

• In animal cells, the cell membrane is the outermost layer of the cell, while in plant cells, the cell membrane separates the cell wall from everything inside the cell.

• In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell.

• In animal cells, the cell membrane controls what comes in and out of the cell, while in plant cells, the cell membrane houses all the genetic material.

• In plant cells, the cell membrane is made of a gel-like material that is green, while in animal cells, the cell membrane is made of a gel-like material that is red.

What are M and O?

• M is a chloroplast, and O is a mitochondria.

• M is the nucleus, and O is the cytoplasm.

• M is a mitochondria, and O is a chloroplast.

• M is the cytoplasm, and O is the nucleus.

Why do all plant cells contain chloroplasts?

• Chloroplasts are necessary for cellular respiration.

• Chloroplasts are necessary for photosynthesis.

• Chloroplasts are necessary for reproduction.

• Chloroplasts are necessary for growth.

What type of organism might contain this type of cell?

• algae

• animal

• bacterium

• plant

If cells were a school building, the cell membrane would most likely be represented by which of the following?

• intercom

• lockers

• teachers and students

• walls and doors

Which organelle is responsible for taking in nutrients, breaking them down, and creating energy rich molecules?

• the mitochondrion

• the Golgi apparatus

• the nucleus

• the vacuole

Cells are specialized to do certain jobs. For instance, muscle cells are in constant motion and require a lot of energy to work. Muscle cells contain more of which organelle?

• cell wall because it produces energy for the cell

• chloroplasts because they produce energy for the cell

• cell membrane because it produces energy for the cell

• mitochondria because they produce energy for the cell
