Nucleus - ANSWER-✔aids in cell division and control of genetic info, contains DNA
(think the egg yolk)
Ribosomes - ANSWER-✔RNA-protein complexes; float freely in cytoplasm; provide
sites for cellular protein synthesis; packages and modifies protein for transportation
and secretion
Endoplasmic Reticulum (ER) - ANSWER-✔specializes in the synthesis and transport
of the protein and lipid components of most of the cells organelles (memory factory)
Golgi complex - ANSWER-✔Organelle that packages and distributes proteins into
vesicles and transports within and outside of cell (refining plant in cytoplasm; traffic
cop- what goes in and out of cytoplasm)
Lysosomes - ANSWER-✔An organelle containing digestive enzymes; digest and
remove wastes, digest debris from dead cells; if ruptured, they can digest cell
contents; autodigestion occurs in starvation
Mitochondria - ANSWER-✔Powerhouse of the cell, organelle that is the site of ATP
(energy) production; pathway for metabolism of carbs, lipids, and amino acids into
ATP; to keep the cell alive; can grow and self-replicate in the cell
Cytoskeleton - ANSWER-✔A network of fibers that holds the cell together, helps the
cell to keep its shape, and aids in movement; "bones and muscle" of the cell; have
cilia to move it on out
, Characteristics of plasma membrane - ANSWER-✔made up of lipids and proteins;
the basic component is a bi-layer of lipid molecules that are responsible for the
structural integrity of the membrane
The _______________ prevents water soluble molecules from entering cells across
the plasma membrane - ANSWER-✔Phospholipid layer
Prokaryote - ANSWER-✔unicellular organism lacking a nucleus; contains NO
organelles (include cyanobacteria, bacteria, and rickettsia)
cellular receptors - ANSWER-✔protein molecules on the plasma membrane, in the
cytoplasm, or in the nucleus that can recognize and bind with specific smaller
molecules called ligands
passive transport - ANSWER-✔The movement of materials through a cell
membrane WITHOUT using energy; no-energy transport of uncharged molecules
through any semi-permeable barrier (occurs down a concentration gradient)
Diffusion - ANSWER-✔Movement of molecules from an area of higher
concentration to an area of lower concentration.
concentration gradient - ANSWER-✔A difference in the concentration of a
substance across a distance.
hydrostatic pressure - ANSWER-✔the mechanical force of water PUSHING against
cellular membranes
Osmosis - ANSWER-✔Diffusion of water through a selectively permeable membrane;
from a region of higher water concentration to a region of lower water
concentration; directly r/t hydrostatic pressure and solute concentration; PULL
active transport - ANSWER-✔the movement of materials through a cell membrane
using energy
mediated transport - ANSWER-✔simultaneous movement of a single solute
molecule in one direction (uniport); of two different solute molecules in one
direction (symport); of two different solute molecules in opposite directions
(antiport)
