BIOLOGY 2e EXAM 2 QUESTIONS
AND ANSWERS IN A SUMMARY FORM
Cell Theory
idea that all living things are composed of cells, cells are
the basic units of structure and function in living things,
and new cells are produced from existing cells
prokaryotic cell
cell lacking a nucleus and is a bacterial cell.
eukaryotic cell
cell that has a nucleus and other membrane-bound
organelles
Structures in both
DNA, RNA, Cytoplasm, Ribosomes, Plasma Membrane
fluid mosaic model
model for structure Plasma Membrane
phospolipid bilayer
double layer of phospholipids and is dynamic.
Protein
help transport and are embedded on RER
Cell Wall
Plants only, called osmosis regulator
Cytoskyleton
made of microtubules & microfilaments, function
intracellular movement, support and movement through
environment.
Nucleus
Control center of the cell. Contains DNA.
, Nucleolus
Found inside the nucleus and produces ribosomes
Nucleoplasm
Fluid inside the nucleus
nuclear pore complex
an array of proteins that line pores in the nuclear
membrane and control which substances enter and leave
the nucleus
nuclear envelope
layer of two membranes that surrounds the nucleus of a
cell
Mitochondria
site of cellular respiration, in both plant and animal cells
Chloroplast
site of photosynthesis in plants only
Cytomembrane System
Assembly, modification, packaging, an shipment of
proteins and lipids.
Rough Endoplasmic Reticulum
Same composition as plasma membrane; forms channels
within cell; studded with ribosomes; transport of proteins to
Golgi body.
Smooth Endoplasmic Reticulum
Same composition as plasma membrane; no ribosomes,
synthesis lipids; detoxification of drugs.
Transport Vesicles
Pieces of ER that carry proteins & lipids to the Golgi body.
these FORM the Golgi body.
Golgi Body
