Life Science Intro

What provides shape and support for the cell?

• Cell wall

• Cell membrane

• Cytoplasm

• Nucleus

What is the function of ribosomes?

• Ribosomes are responsible for energy production.

• Ribosomes are responsible for protein synthesis.

• Ribosomes are responsible for DNA replication.

• Ribosomes are responsible for lipid synthesis.

What is an advantage of using a cell model when studying cells?

• Cell models show cell shape and tiny organelles found in the cell.

• Cell models are less expensive than real cells.

• Cell models can be used to grow actual cells.

• Cell models provide a 3D view of the entire organism.

Which statement is NOT part of Cell Theory?

• All cells contain a nucleus.

• All living organisms are composed of one or more cells.

• Cells arise from pre-existing cells.

• All cells have a cell membrane.

What is the function of the cell membrane?

• It provides structural support to the cell.

• It controls what enters and exits the cell.

• It stores genetic information.

• It produces energy for the cell.

What distinguishes prokaryotic cells from eukaryotic cells?

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Prokaryotic cells are larger than eukaryotic cells.

• Prokaryotic cells do not have a nucleus, while eukaryotic cells do.

• Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.

What is the role of mitochondria in a cell?

• Mitochondria produce energy through cellular respiration.

• Mitochondria store genetic information.

• Mitochondria are responsible for protein synthesis.

• Mitochondria regulate cell division.

What is the significance of the cell wall in plant cells?

• It provides structure and protection to plant cells.

• It allows for gas exchange in plant cells.

• It stores nutrients for plant cells.

• It aids in photosynthesis in plant cells.

Which of the following is NOT a characteristic of a eukaryotic cell?

• Nucleus

• Mitochondria

• Flagellum

• Endoplasmic reticulum

What is the difference between plant and animal cells?

• Plant cells have a cell wall and chloroplasts, while animal cells do not.

• Animal cells have a cell wall and chloroplasts, while plant cells do not.

• Both plant and animal cells have a cell wall and chloroplasts.

• Plant cells are smaller than animal cells.
