organelle that links amino acids together to form proteins
Ribosome
organelle composed of numerous membranes that are used to convert solar energy into chemical energy; contains chlorophyll
Chloroplast
stack of flat, membrane-enclosed spaces containing enzymes that process, sort, and deliver proteins
Golgi Apparatus
interconnected network of thin, folded membranes that produce, process,a nd distribute proteins
Endoplasmic Reticulum
double-layer of phospholipids that forms a boundary between a cell and the surrounding environment and controls the passage of materials into and out of a cell
Cell Membrane
energy-requiring movement of molecules across a membrane from a region of lower concentration to a region of higher concentration
Active Transport
jellylike substance inside cells that contains molecules and in some cells organelles
Cytoplasm
the process by which molecules move from an area of higher concentration to an area of lower concentration
Diffusion
uptake of liquids or large molecules into a cell by inward folding of the cell membrane
Endocytosis
solution that has a higher concentration of dissolved particles compared with another solution
Hypertonic
solution that has a lower concentration of dissolved particles compared with another solution
Hypotonic
Solution that has an EQUAL concentration of dissolved particles compared with another solution
Isotonic
bean-shaped organelle that supplies energy to the cell and has its own ribosomes and DNA
Mitochondrion
molecule that forms a double-layered cell membrane; consists of a glycerol, a phosphate group, and two fatty acids
Phospholipid
parts of the endoplasmic reticulum to which ribosomes are attached on the cytoplasmic side
Rough ER
part of the endoplasmic reticulum which does NOT have ribosomes attached, hence it is smooth
Smooth ER
A membrane that allows some molecules to pass through but does not allow other molecules to pass through
Selectively Permeable
