Question Answer
cytoskeletonnetwork of protein filaments within some cells that help the cell maintain it's shape and is involved in many forms of cell movement
centrioleone of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope
ribosomesmall particle in the cell on which proteins are assembled made of RNA and protein
lysosomecell organelle filled with enzymes needed to break down certain materials in the cell
vacuolecell organelle that stores materials such as water, salts, proteins and carbohydrates
chloroplastorganelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
mitochondriacell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cells use
endoplasmic reticuluminternal membrane system in cells in which lipid components of the cells membrane are assembled and some proteins ar emodified
golgi apparatusstack of membranes in the cell that modifies, sorts and packages proteins from the endoplasmic reticulum
organellespecialized structure that performs important cellular functions within a eukaryote cell
cellcollection of living matter enclosed by a barrier that separates the cell from its surroundings, basic unit of all life
cell theoryidea that all living things are composed of cells and that cells are the basic units of structure and function in living things and new cells are produced from existing cells
nucleusthe center of the atom which contains the protons and neutrons in a cells structure that contains the cells generic material DNA and controls the cells activities
nucleolussmall dense region within most nuclei in which the assembly of proteins begins
cytoplasmmaterial inside the cell membrane not including the nucleolus
cell membranethin flexible barrier around a cell that regulates what enters and leaves the cell
cell wallstrong supporting layer around the cell membrane in plants, algae and some bacteria
lipid bilayerdouble layered sheet that forms the core of nearly all cell membranes
prokaryoteunicellular organism lacking a nucleus
eukaryoteorganism whose cells contain nuclei
