Cell membrane Cell wall Centrioles thin flexible barrier around a cell regulates what enters and leaves the cell Composed of phospholipids strong layer around the cell membrane in plants algae and some bacteria Composed of cellulose in plants Two small tube like structures in cytoplasm near the nucleus that aid in cell division chloroplast plastid containing chlorophyll and other pigments performs photosynthesis Chromatin Cytoskeleton Cytosol Golgi leucoplast lysosomes granular material visible within the nucleus consists of DNA tightly coiled around proteins Just chillin DNA a network of protein filaments that holds the cell together helps the cell to keep its shape and aids in movement the soluble portion of the cytoplasm which includes molecules and small particles such as ribosomes but not the organelles covered with membranes An organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify store and route products of the endoplasmic reticulum process package ship plastid generally colorless that synthesizes and stores starch and oils Cell organelle filled with enzymes needed to break down certain materials in the cell Mitochondria rod shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions power house produces energy Nuclear Membrane Nucleolus Peroxisomes Ribosomes double membrane lipid bilayer surrounding the nucleus that controls what enters and leaves a small round body of protein in a cell nucleus where ribosomes are made synthesized and partially assembled Membranous sacs containing enzymes used to break down hydrogen peroxide alcohol and other harmful substances small particle in the cell on which proteins are assembled made of RNA and protein Rough Endoplasmic Reticulum A network of interconnected internal membranes forming channels within the cell Covered with ribosomes Transportation production of proteins by attached ribosomes Smooth Endoplasmic Reticulum An endomembrane system where lipids are synthesized calcium levels are regulated and toxic substances are broken down Vacuoles Membrane surrounded bags Small in animal cells large in plant cells Function Storage of food water and other materials
