cell wall
a rigid structure that surrounds the cell membrane and provides support to the cell
ribosome
cell organelle composed of RNA and proteins: the site of protein synthesis
endoplasmic reticulum
a system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids
mitochondrion
in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
Golgi complex
cell organelle that helps make and package materials to be transported out of the cell
vesicle
a small cavity or sac that contains materials in a eukaryotic cell; forms when part of a cell membrane surrounds the material to be taken into the cell, or transported within it
lysosome
a cell organelle that contains digestive enzymes
lipids
fats, cholesterol; group of compounds that do not dissolve in water
phospholipid
• hydrophobic
• hydrophilic
lipid that contains phosphorus
•water fearing, form inner part of membrane
•water loving, form outer part of membrane
cytoskeleton
web of proteins in the cytoplasm, act as muscle and skeleton
nucleolus
large organelle in a eukaryotic cell containing DNA; where cells begin making ribosomes
amino acids
about 20 different organic molecules that are used to make protein
chloroplasts
organelles in plant and algae cells in which photosynthesis takes place
vacuole
large vesicle, some act as lysosomes in plant and fungal cells, store water and other materials
