Cell Theory

What are prokaryotic cells?

• Cells with a nucleus, such as plants and animals.

• Cells without a nucleus, such as bacteria.

• Cells that contain membrane-bound organelles.

• Cells that are always multicellular.

What tool do you use to view the cells?

• Microscope

• Telescope

• Stethoscope

• Periscope

What is cytoplasm?

• The jelly-like substance inside the cell where organelles are found.

• The outer membrane of the cell that protects it from the environment.

• The part of the cell responsible for energy production.

• The genetic material found within the nucleus of the cell.

Which statement is a part of the cell theory?

• All cells come from preexisting cells.

• All cells are identical in structure and function.

• All living organisms are made up of a single cell.

• All cells can spontaneously generate from non-living matter.

What is the role of the nucleus?

• It acts as the control center of the cell, containing DNA.

• It provides energy to the cell through ATP production.

• It is responsible for protein synthesis in the cell.

• It helps in the detoxification of harmful substances.

What is the purpose of cell division?

• To allow growth, repair, and reproduction of organisms.

• To increase the size of the cell only.

• To produce energy for the cell.

• To eliminate waste from the cell.

What is the function of the cell membrane?

• It provides structural support to the cell.

• It controls what enters and leaves the cell.

• It stores genetic information.

• It produces energy for the cell.

What is an organelle?

• A specialized structure within a cell that performs a specific function.

• A type of cell membrane that protects the cell.

• A group of cells that work together to perform a specific task.

• A fluid that fills the cell and holds organelles in place.

The basic unit of life is called a (n)

• Cell

• Tissue

• Organ

• Organism

What is the main idea of Cell Theory?

• All living things are made of cells.

• Cells are the basic unit of life.

• All cells come from pre-existing cells.

• Cells can exist independently of living organisms.
