Biosphere and Taxonomy Flashcards
Prokaryotic cells characteristics
smaller than eukaryotic cells. less complex, no membrane bound organelles, no defined nucleus
eukaryotic cells characteristics
bigger than prokaryotic cells. More complex, it has a membrane bound organelles
Emergent properties
a thing in which a whole system has, but not in its individual parts
Schleiden and Schwann’s cell theory
All organisms are made up of cells
All cells come from only pre-existing cells
Cells is the basic structural and functional unit of an organism
Plasma Membrane
Animal and Plant cell
boundary which separates the living cell from its nonliving surroundings
regulates entry and exit of cell, and the traffic in the cell
Nucleus
Animal and Plant cell
house of genetic information
facilitates the replicating process
Mitochondria
Animal and Plant cell
Powerhouse of cell
site of cellular respiration, which processes the generation of ATP
Chloroplast
Plant cell
Converts light-energy into chemical energy during photosynthesis
Ribosomes
Animal and Plant cell
make protein
free in cyto-plasm or attached to endoplasmic reticulum
Endoplasmic Reticulum
Animal and Plant cell
Rough: making secretory proteins
Smooth: synthesis of lipid,metabolism of carbohydrates, and can detoxify drugs and poisons
Lysosomes
Animal and Plant cell Destruction of ingested organisms Breakdown of old organelles activate release of stored material autolysis
Vacuoles
Plant cell
storing, importing, and exporting materials
Endomembrane system
Animal and Plant cell
Regulates protein traffic and performs metabolic functions
Components:Er, Golgi complex, Lysosomes, various vacuoles, cell membrane
Plant cell wall
made up of cellulose
Bacteria cell wall
made up of peptidoglycan
