Name the organelle known as the 'powerhouse' of the cell.
nucleus
endoplasmic reticulum
ribosomes
mitochondria
What is the function of the cell membrane?
Produce proteins for the cell
Store energy for the cell
Regulate what enters and leaves the cell, provide protection and support, and allow for cell communication.
Regulate temperature within the cell
What is the function of the nucleus in a cell?
Control center of the cell
Waste storage
Energy production
Cell wall formation
Name the organelle responsible for protein synthesis.
chloroplast
ribosome
mitochondria
nucleus
What is the function of the mitochondria in a cell?
Produces energy through cellular respiration
Produces glucose through photosynthesis
Regulates cell division
Stores genetic information
What is the difference between plant and animal cells?
Animal cells have a cell wall, while plant cells do not.
Plant cells have flagella for movement, while animal cells do not.
Plant cells have a cell wall and chloroplasts, while animal cells do not.
Plant cells have a nucleus, while animal cells do not.
What is the function of the endoplasmic reticulum in a cell?
Energy production in the cell
Regulation of cell division
Protein and lipid synthesis, and transportation of molecules within the cell
Storage of genetic material
What is the function of the Golgi apparatus in a cell?
Storing genetic information
Regulating cell division
Modifying, sorting, and packaging proteins and lipids
Generating energy for the cell
Explain the process of osmosis in a cell.
Osmosis is the movement of oxygen molecules into the cell
Water molecules move from an area of higher concentration to an area of lower concentration
Water molecules move from an area of lower concentration to an area of higher concentration
Osmosis only occurs in plant cells, not animal cells
