Biology Final Part 2 Flashcards
Golgi Apparatus
packs and ships proteins out of the cell
Endoplasmic Reticulum
delivers proteins with ribosomes
Plasma Membrane
bi-layer, controls movement of substances in and out
Mitochondria
‘powerhouse’ of the cell
Ribosome
Makes proteins in both prokaryotes and eukaryotes
Cell Wall
found outside the cell membrane, provides support and protection
Vacuole
store nutrients and water cell can rely on for survival
Central Vacuole
storage tank for water, food, and waste
Nucleus
control center, directs cell activities, contains DNA
Nucleolus
dark-staining structure in the nucleus; makes ribosomes
Cytoplasm
gel-like mixture within a cell, surrounded by cell membrane, contains cell structures (nucleus, ER)
Lysosome
digestive ‘plant’ for proteins, fats, and carbohydrates; cell breaks down if lysosome explodes
Chloroplast
found in plant cells, contains chlorophyll
Centriole
helps animal cells divide
Prokaryote
believed first to evolve, no membrane band, nucleus, nor organelles
Eukaryote
2 major types, plant- rectangular, chloroplasts, animal- circular, vacuole, cell wall
Plant vs Animal Cell
plant cells have a cell wall, animal cells have a distinct nucleus
Levels of Cellular Organization
molecules - macromolecules - organelles - cells - tssues - organs - organ systems - organism
Active Transport
requires energy, low to high concentration (swimming up stream)
Passive Transport
doesn’t require energy, high to low concentraion (perfume, food coloring)
Protein Pump
Active, sodium-potassium pump is one 3 sodium in 2 potassium out
Endocytosis
how the cell brings in large particles
Exocytosis
cell getting rid of waste
Ion Channel
specific to what ion it allows to enter the cell
