-plasma membrane ANS a microscopic membrane of lipids and proteins that forms the external
boundary of the cytoplasm of a cell or encloses a vacuole, and that regulates the passage of molecules in
and out of the cytoplasm.
- Golgi apparatus ANS A system of membranes that modifies and packages proteins for export by the
cell
- Vesicle ANS Small membrane-bound sac that functions in moving products into, out of, and within a
cell.
- Ribosomes ANS site of protein synthesis
- Mitochondrion ANS bean-shaped organelle that supplies energy to the cell and has its own
ribosomes and DNA.
- Centrioles ANS Cell organelle that aids in cell division in animal cells only
- Nuceus ANS the central and most important part of an object, movement, or group, forming the
basis for its activity and growth.
, - Nucleolus ANS Makes ribosomes
- Smooth Endoplasmic Reticulum ANS An endomembrane system where lipids are synthesized,
calcium levels are regulated, and toxic substances are broken down.
- Rough Endoplasmic Reticulum ANS System of internal membranes within the cytoplasm.
Membranes are rough due to the presence of ribosomes. functions in trANSport of substances such as
proteins within the cytoplasm
- Lysosomes ANS An organelle containing digestive enzymes
- cell wall ANS A rigid layer of nonliving material that surrounds the cells of plants and some other
organisms.
- Chloroplasts ANS Site of photosynthesis
- Vacuole ANS Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
- Amyloplast ANS starch storage
- Plasmodesmata ANS An open channel in the cell wall of plants through which strands of cytosol
connect from adjacent cells
- pits ANS openings in the lateral walls of xylem cells allowing water and nutrients to leak into
surrounding tissues.
- resting potential ANS electrical charge across the cell membrane of a resting neuron
