Module 3 Flashcards
plasma membrane
encloses cell, controls passage of things in and out. present in all
cytoplasm
provides cell structure, gloppy liquid. present in all
nucleoid
location of dna. present in prokaryotes
nucleus
houses dna, directs synthesis of ribosomes and proteins
ribosomes
protein synthesis
Mitochondria
ATP production, cellular respiration. present in eukaryotes
peroxisomes
oxidizes and breaks down fatty acids and amino acids, detoxifies poisons. present in eukaryotes
vesicles/vacuoles
storage and transport, digestive function in plant cells. present in eukaryotes
centrosome
unspecified role in cell division, organizing center of microtubules present in animal cells
lysosomes
digestion of macromolecules, recycling of worn out organelles. present in animal cells
cell wall
protection, structural support and maintenance of cell shape. present in some prokaryotes and plant cells
chloroplasts
photosynthesis. found in plant cells
endoplasmic reticulum
rough: modifies proteins, smooth: synthesizes lipids. found in eukaryotes
golgi apparatus
modifies sorts tags packages and distributes lipids and proteins. found in eukaryotes
cytoskeleton
maintains shape, secures organelles, allows cytoplasm and vesicles to move around, enables unicellular organisms to move independently. present in all cells
Diffusion
Passive, move evenly into space, oxygen and carbon dioxide
Facilitated diffusion
Passive, proteins help, glucose
Osmosis
Passive, water across a membrane, water
Active transport
Active, pumps, NA ions and K ions
Endocytosis
Bulk transport into the cells, proteins and bacterial cells
Exocytosis
Bulk transport out of the cell, proteins and waste
Hypertonic
Greater solute
Hypotonic
Lesser solute
Isotonic
Even solute
