cellular organelles

cytosol

surrounds cell membranes, jelly-like substance, transports molecules

nucleoid

non-membrane enclosed region in pro. cells where chromosomes are

cytoplasm

between nucleus and plasma membrane in all cells

plasma membrane

selective barrier at boundary of every cell, regulates chem. composition

nucleus

atom’s central core in E cells where chromosomes are

nuclear envelope

surrounds nucleus in E. cell, regulates traffic with cytoplasm

ribosomes

carries out protein synthesis

nuclear lamina

protects nucleus in E cells

nucleolus

makes ribosomes, contains RNA

smooth ER

synthesizes lipids

endoplasmic reticulum

consists of tubules and sacs called cisternae

rough ER

processes glycoproteins

golgi apparatus

modifies proteins; dynamic; trans and cis face

lysosome

digests macromolecules, acidic environment for enzymes

vacuoles

large, come from ER and Golgi

phagocytosis

cell eats large particle

contractile vacuole

extracts water out of protist cells

central vacuole

stores inorganic ions in plant cells, supports cell shape

peroxisome

has catalase, transfers hydrogen to oxygen

catalase

converts H2O2 to water

mitochondria

cellular respiration, creates ATP, surrounded by phospolipid bilayers
