cell correct answers the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm nucleus correct answers a part of the cell containing DNA and RNA and responsible for growth and reproduction DNA correct answers deoxyribonucleic acid. Double-stranded nucleic acid twisted into a helical shape; its base sequence encodes the primary hereditary information for all living organisms and many viruses. plasma (cell) membrane correct answers phospholipid bilayer containing cholesterol and proteins. Contains receptors for communication; forms intercellular connections and boundaries; acts as a physical barrier to enclose cell contents; regulates movement into and out of the cell. interstitial fluid correct answers liquid found between the cells of the body that provides much of the liquid environment of the body selectively permeable correct answers a property of cell membranes that allows some substances to pass through, while others cannot cytoplasm correct answers the region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes); contains a gel-like material and cell organelles organelles correct answers are structures that work like miniature organs, carrying out specific functions in the cell mitochondria correct answers powerhouse of the cell, organelle that is the site of ATP (energy) production ribosome correct answers a cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; Consists of rRNA and protein molecules, which make up two subunits. ribosomes attach to mRNA and move down it one codon at a time and stop until tRNA brings the required amino acid; when a ribosome reaches a stop codon it falls apart and releases the completed protein molecules ER endoplasmic reticulum correct answers complex network of interconnected membranes that form falttened sacs elongated canals and fluid filled vesicles Connected with the cell membrane nuclear envelope and some organelles Functions a tubular communication system to manufacture and transport substances golgi complex correct answers the cell organelle that modifies, packages, and transports materials out of the cell
