Basic Introduction to Cell Flashcards
It serves as storage for hereditary information (nucleus or nuecleiods)
Deoxyribonucleic Acid (DNA)
It is a fluid surrounding the structures of the cell
Cytoplasm
It controls what goes in and out of the cell
Plasma membrane
Site of protein synthesis
Ribosomes
- It means “before nucleus”
- Simplest organism, and are very small
- No membrane bound organelles
- One-celled organisms: Bacteria and Archaea
Prokaryotic cell
Eu means what
True
Karyon refers to
Nucleus
- Contains organelles surrounded by membranes
- Found in most living organisms
Eukaryotic cell
It carry out genetic control of the cell
Nucleus and Ribosomes
Organelles involved in the manufacture, distribution, and breakdown of molecules
Endomembrane System
Energy processing
Mitochondria
Provides structural support, movement, and communication between cells
Plasma membrane, cell wall, cytoskeleton
- Membrane enclosing the nucleus.
- Protein-lined pores allow material to move in and out
Nuclear envelope
DNA plus associated proteins
Chromatin
Condensed region where ribosomes are formed
Nucleolus
Form the mitotic spindle and maintain cell shape
Microtubules
Microtubule-organizing center
Centrosome
Fibrous proteins that hold organelles in place
Intermediate filaments
Fibrous proteins; form the cellular cortex
Microfilaments
Digests food and waste materials
Lysosome
It modifies proteins
Golgi apparatus
Produces energy
Mitochondria
Associated with ribosomes; makes secretory and membrane proteins
Rough Endoplasmic reticulum
Makes lipids
Smooth Endoplasmic reticulum
