What is the nucleus?
Contains the cell’s genetic material (DNA) and regulates gene expression.
What are mitochondria?
The site of ATP (energy) production.
What are ribosomes?
Complexes where protein synthesis occurs.
What is the Golgi Complex?
Modifies, sorts, and packages proteins and lipids for transport out of the cell.
What are lysosomes?
Contains enzymes for digestion of macromolecules and waste processing.
What is the cytoskeleton?
Network of protein filaments that provides structural support and facilitates movement.
What is the plasma membrane?
Semi-permeable membrane that controls what enters and exits the cell.
What are the main organelles of a cell?
Nucleus, mitochondria, ribosomes, Golgi Complex, lysosomes, cytoskeleton, and plasma membrane.
Describe the structure and function of the nucleus.
The nucleus is a membrane-bound organelle that contains the cell's genetic material (DNA) and regulates gene expression, similar to a library that stores information needed for functioning.
Describe the structure and function of mitochondria.
Mitochondria are double-membraned organelles with folded inner membranes, responsible for ATP production, akin to power plants generating energy for the city.
Describe the structure and function of ribosomes.
Ribosomes are tiny complexes made of RNA and proteins that can be free-floating or bound to the endoplasmic reticulum, serving as factories for protein synthesis, much like construction sites building proteins.
Describe the structure and function of the Golgi Complex.
The Golgi Complex is a series of stacked membranes that modifies, sorts, and packages proteins and lipids, acting like a post office that dispatches finalized products to their destinations.
Describe the structure and function of lysosomes.
Lysosomes are membrane-bound vesicles containing enzymes, functioning as the cell’s waste disposal system, similar to a recycling center processing materials.
Describe the structure and function of the cytoskeleton.
The cytoskeleton is a network of protein filaments and tubules that provides structure and aids in cell movement, comparable to the scaffolding of a building that supports its structure.
Describe the structure and function of the plasma membrane.
The plasma membrane is a semi-permeable lipid bilayer that controls what enters and exits the cell, similar to a security gate regulating access to a facility.
