organelles Flashcards
cell wall
provides rigid structure of cell in plant cells and some prokaryotic cells
cell membrane
bilayer phospholipid structure that gives cell structure, separates external and internal environments, semi-permeable membranes allow only certain materials through
cytoplasm
jelly inside of cell that supports the cells and is the location of cellular reactions
cytoskeleton
networks of microfibers and microfilaments (proteins) that provide roadways for vesicle movement and provide structure
centrosomes
help w/ cell division in animal cells
nucleus
stores genetic info and is the command center of the cell, only in eukaryotes
Nucleolus
the jumble of DNA/RNA within the nucleus that help make ribosomes within the nucleus
ribosomes
site of protein synthesis, on rough ER or free floating in cytoplasm
vacuole
storage containers. Plants have 1 large central vacuole for water and animal cells have multiple smaller ones
Smooth ER
synthesizes lipids, synthesizes steroid hormones, detoxifys
Rough ER
involved in protein synthesis
Golgi Apparatus
receives proteins from ER and processes them and packages them for transport
Vesticles
transport proteins that are too big to leave cell on their own, made of same thign as membrane, fuses to membrane and opens
lysosomes
help digest biomolecules and break down cellular waste
peroxisomes
breaks down fatty acids and hydrogen peroxide
