Cell Organelles Flashcards
Plasma membrane
Surrounds and protects the cell
Cytosol
Fluid portion of cell (intracellular fluid)
Ribosomes
Makes proteins
Prokaryotes
Bacteria
Eukaryotes
Plant, animals, fungus, and proteins
Cytoplasm
Liquid in cell
Cytoskeleton
Proteins that support and organize the cell
Microtubules
Made of protein, involved in placement of organelles help control motility (9+2 arrangement of Tubulidentata in cilia and flagella)
Microfilaments/actin
Help in contraction/movement Actin=Action!
Pseudopods and phagocytosis
White blood cell movement
Peristalsis
Digestive track
Intermediate filaments
Act as a tension rod
Keratin
Tough protein, makes scales and hair
Nuclear membrane
Membrane in nucleus
Nuclear lamina
Proteins that shape the nucleus
Chromatin
Thread like matrix in nucleus
Nucleolus
Areas of highly used DNA to make RNA
Nucleus functions
Contains codes for proteins and heredity (copies DNA correctly for next generation)
Endoplasmic reticulum (smooth)
Transports proteins
Endoplasmic reticulum (rough)
Transports lipids and carbs
Lumen
Hollow organ
