NLN PAX SGI 100% Verified Questions & Answers
Q: cell
Answer:
the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm
Q: nucleus
Answer:
a part of the cell containing DNA and RNA and responsible for growth and reproduction
Q: DNA
Answer:
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.
Q: plasma (cell) membrane
Answer:
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.
Q: interstitial fluid
Answer:
liquid found between the cells of the body that provides much of the liquid environment of the body
Q: selectively permeable
Answer:
a property of cell membranes that allows some substances to pass through, while others cannot
Q: cytoplasm
Answer:
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
Q: organelles - are structures that work like miniature org
Answer:
, carrying out specific functions in the cell
Q: mitochondria
, Answer:
powerhouse of the cell, organelle that is the site of ATP (energy) production
Q: ribosome
Answer:
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
Q: 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 - 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 tr
Answer:
port substances
Q: golgi complex - the cell organelle that modifies, packages, and tr
Answer:
ports materials out of the cell
Q: lysosome
Answer:
membrane-bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides
Q: cell wall
Answer:
strong supporting layer around the cell membrane in plants, algae, and some bacteria
Q: chloroplast
Answer:
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into
chemical energy
Q: vacuole
Answer:
cell organelle that stores materials such as water, salts, proteins, and carbohydrates
Q: chromatin
Answer:
the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, during mitotic (cell)
division the chromatin condenses into chromosomes
