- 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
