DownloadWhat is the primary function of the cell membrane in eukaryotic cells?
Flip card
The primary function of the cell membrane is to protect the cell by acting as a barrier and to regulate the movement of substances in and out of the cell.
Describe the process of osmosis.
Flip card
Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
What is the role of mitochondria in the cell?
Flip card
Mitochondria are the powerhouse of the cell, responsible for producing energy in the form of ATP through cellular respiration.
Define homeostasis and give an example.
Flip card
Homeostasis is the process by which living organisms regulate their internal environment to maintain a stable, constant condition. An example is the regulation of body temperature in humans.
Explain the difference between a prokaryotic and a eukaryotic cell.
Flip card
Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have a defined nucleus and are organized into complex structures with organelles.
What is the function of ribosomes in the cell?
Flip card
Ribosomes are responsible for protein synthesis, translating genetic information from mRNA to build proteins.
Describe the role of the Golgi apparatus.
Flip card
The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
What is the significance of the cell cycle?
Flip card
The cell cycle is significant because it ensures the proper division and replication of cells, allowing for growth, development, and repair in multicellular organisms.
