|
What are the two main cells?
|
Prokaryotic or Eukaryotic cells
|
|
|
What is considered a prokaryotic cell?
|
It's a cell that has no true nucleus and no membrane-bounded organelles.
|
|
|
What is considered a eukaryotic cell?
|
They have true nuclei and their organelles have membranes.
|
|
|
What are ribosomes?
|
They are small particles that produce the cell's proteins and enzymes. They consists of a small and large subunit.
|
|
|
What is a endoplasmic reticulum?
|
The ER is a higly convoluted membrane that secretes enzymes and produces other members.
|
|
|
What is a golgi apparatus?
|
It is made up of many flattened membrane-bound vesicles. It also secretes protein.
|
|
|
What are lysosomes?
|
Produced by the golgi complex, they are small membrane-bounded bags that are filled with enzymes. These enzymes break down and digest macromolecules.
|
|
|
What is endocytosis?
|
It's the process of bringing substances into the cell.
|
|
|
What is a vaculoe?
|
They are large membranous sacs that store food, waste, and other stuff. They can contract and expel water out of the cell, or expand and play a role in cellular elongation.
|
|
|
What is a cytoskeleton?
|
It is the support structure of the cell. It is associated with three types of fibers: Microtubules, intermediate filaments, and microfilaments.
|
|
|
What are microtubules?
|
They are thick, hollow rods which are mostly found in the cytoplasm. (Cilia and flagella)
|
|
|
What are intermediate filaments?
|
Midsize protein fibers.
|
|
|
What are microfilaments?
|
They are the smallest fibers (Actin - contractile filament in muscle)
|
|
|
What are the two main cell cycles?
|
Interphase and mitosis.
|
|
|
What are the three parts to interphase?
|
The S phase, and the two gaps (G1 and G2) before and after the S phase.
|
|
|
What is binary fission
|
The process in which prokaryotic cells divide.
|
|
|
What are the two possible processes in which eukaryotic divide?
|
Mitosis or meiosis.
|
|
|
What are the steps in mitosis?
|
Prophase, metaphase, Anaphase, and telophase.
|
