Organelles Flashcards
(11 cards)
Cytoplasm
fluid within cell membrane providing a medium for chemical reactions and holding organelles in place
cytosol
fluid portion of cytoplasm
Centrioles
Pair of cylindrical structures located near the nucleus—- used in mitosis/meiosis (cell reproduction)
endoplasmic reticulum
network of channels and flattened sacs that extend almost everywhere in cytoplasm transporting materials
rough er ribosomes attached
smooth er no ribosomes attached
ribosomes
site of protein synthesis mostly attached to er membrane but can be free in cytoplasm
cytoskeleton
micro filaments and microtubules
provide structural support
help move materials/ organells
lysosomes
small spheres that contain digestive enzymes
break down worn out organelles
break down materials brought into the cell
nucleus and nucleolus
nucleolus made mostly of RNA
contain genetic material
nuclear pore( allows molecules to pass)
nucleolus located inside the nucleus
mitochondria
Release energy for the cell through respiration
golgi boy
modify and package proteins secreted in vesicles
cell membrane (remember drawing for it)
Boundary separating cells from intra and extracellular environments
