the following are the 3 parts of what theory?
1. structural building blocks of all plants and animals
2. produced by division of preexisting cells
3. smallest structural units that perform vital functions
cell theory Schleiden and Schwann 1839
what are the 2 types of cells
sex cells and somatic cells
cells float in a watery medium called.......

it is high in Na+ ions
extracellular fluid
the exterior of the cell is surrounded by this
- thin and delicate
- composed of phospholipids, proteins, glycolipids, and cholesterol
- phospholipid bilayer
cell membrane
this separates the extracellular fluid from the cell contents
cytoplasm
the following are functions of what organelle?
-controls entry and exit of substances (permeability)
.... passive and active transport
cell membrane
this type of passive process is the movement from high concentration to low concentration
diffusion
this type of passive process is the diffusion of water
osmosis
this type of passive process is solutes/ dissolved nutrients by hydrostatic force cross the membrane with water
filtration
this type of passive process is when special carrier proteins transport large molecules
facilitated diffusion
this type of transport required energy and may have carrier mechanism pumps
active transport process
packaging of extracellular materials into a vesicle for transportation into the cell.... requires energy
endocytosis
cell drinking
pinocytosis
cell eating
phagocytosis
this type of transport occurs when specific molecules are brought in the cytosol
receptor mediated endocytosis
intracellular materials transported out of cell into extracellular fluid
exocytosis
this is the intracellular fluid
- high in potassium
-high in proteins
- low in carbs
- high in amino acids
-high in lipids
--inclusion bodies
cytosol
this is the term for organelles being in actual contact with the cytosol
non-membranous
this gives a cell strength and flexibility and is non membranous ... composed of 4 things
cytoskeleton
what 4 things make up the cytoskeleton?
1. microfilaments
2. microtubules
3. intermediate filaments
4. thick filaments
this part of the cytoskeleton is mainly actin, anchors to the cell membrane, forms dense network with cell membrane, and can cause movement of cell when interaction with myosin
microfilaments
this part of the cytoskeleton is made up of hollow tubes that give strength and rigidity to the cell. Thto organelle to give it structure ey are responsible for changing the shape of cell and can attach
microtubule
this part of the cytoskeleton provides strength and stabilizes position of organelles
intermediate filaments
this part of the cytoskeleton is the myosin
thick filaments
this is a non-membranous organelle that has small finger like projections on cell membrane that...
- increase surface area
- involved in active absorption
- microfilaments inside anchor them to dense network
microvilli
this is made up of microtubules and is important in cell division
centriole
this is made up of microtubules and is a 9+2 array that beat or sway to move secretions or fluid
cilia
this is made up of microtubules and resemble cilia, but larger
flagellum
this is a non-membranous organelle that is small dense granules that contain mainly RNA
- manufacture proteins
-either free or fixed (attached to ER)
ribosomes
this is a term that means "has a membrane that isolates contents from cytosol and allows organelles to manufacture or store secretions"
membranous
this organelle has double memrane and inner folds called cristae
- produces most of energy to keep cell alive
- number of this organelle depends on the cell's energy demands
mitochondria
this organelle is the control center of cell operations
- determines structural and functional characteristics by controlling what proteins are synthesized
- direct processes done in cytosol
nucleus
this is connected to rough ER and encloses the nucleus
nuclear envelope/ membrane
content of nucleus
- contains chromosomes- DNA- 23 pair
nucleoplasm
nuclear organelles that synthesize RNA
nucleulos
network of intracellular membranes that form flat sheets and round chambers called cisternae
- synthesis of carbs, lipids, and proteins
-storage of synthesized molecules
-transport of molecules
ER
this ER has ribosomes for transport
rough ER
this ER is responsible for synthesis of lipids and carbs (no ribosomes)
smooth ER
this organelle is a series of membranous plates- cisternae that give rise to lysosomes and secretory vesicles
- synthesis and packages secretions
- packages special enzymes
Golgi Apparatus
package secretions of rough ER are carried by this to Golgi
transport vesicles
these are formed by Gogli and fuse cell membrane to discharge their contents into extracellular fluid
secretory vesicles
vesicles from Golgi apparatus that remain in cell's cytoplasm
a) removes bacteria and organic debris from cytoplasm and isolate it into
b) contains digestive enzymes
c) releases nutrient components into cytosol and expels waste by
exocytosis
lysosomes
block passage of water and other substances between cells
a. also called zonula occludens
tight junctions
adhering type junction that occurs as a sheet between cells
zonula adherens
strong junctions which resist stretching and twisting

aka desmosome-- like a spot weld between cells
macula adherens
allows for passage of small molecules
gap junctions
