BIOCHEMISTRY CONCEPTS DRILL PACK
ANSWER SHEET
◉ cell membrane.
Answer: cells security system, surrounds and protects the cell,
controls what enters and exits the cell
◉ cytoplasm.
Answer: gel-like substance inside the cell, where cell processes
(chemical reactions) occur, 80% water
◉ cell wall.
Answer: tough structure that surrounds and protects plant cells,
gives cells shape, made of cellulose
◉ nucleus.
Answer: control center of the cell, contains directions for the entire
cell, DNA is found here, surrounded by a nuclear membrane
◉ chloroplast.
,Answer: green organelle, in plant cells, photosynthesis, captures
energy from the sun to make glucose
◉ mitochondria.
Answer: stores and releases cell's energy, "powerhouse"
◉ ribosomes.
Answer: protein factories, make proteins, some float freely in the
cytoplasm and others are attached to the ER
◉ endoplasmic reticulum.
Answer: cell's railroad track, moves material around in the cell,
smooth-no ribosomes, rough-has ribosomes, also creates some
chemical compounds used by the cell
◉ Golgi body.
Answer: cell's post office, sorts and packages proteins into vesicles,
vesicles deliver substances in the cell and also attach to the cell
membrane to release materials to the outside
◉ nucleolus.
Answer: manufactures the proteins that make up the ribosomes,
found in the nucleus
, ◉ lysosome.
Answer: cell's landfill, digest food molecules, cell wastes, and worn
out cell parts, formed by the Golgi bodies
◉ vacuole.
Answer: temporarily stores food, water, waste; rather large in plant
cells (like a vacuum stores dirt)
◉ tissue.
Answer: a group of cells working together to perform a particular
function
◉ organ.
Answer: two or more tissues working together to perform a function
◉ vesicle.
Answer: small packages that are created by the Golgi body that
deliver nutrients and proteins throughout the cell, or transporting
wastes to the cell membrane to be expelled from the cell
◉ centrioles.
Answer: bundles of microtubles that organize the movement of the
chromosomes during cell division
