|
|
Unicellular? example?
|
organism made up of only one cell, an amoeba is unicellular
|
|
|
|
Colony?
|
group of unicelular organisms living together
|
|
|
|
Multicellular?
|
organisms made up of multiple cells with differentiation
|
|
|
|
Cell differentiation?
|
each type of cellhas aunique job
|
|
|
|
3 variations in cells are?
|
Size, shape, internal organization
|
|
|
|
Surface are tovolume ratio in cell?
|
as the surface area increasesthe volume increases a full factor of 10 more than the area
|
|
|
|
what moves throughout cell to keep it alive?
|
nutrients such as sugars/carbs, proteins, h2o, o2
|
|
|
|
What happens if a cell is to samll?
|
It can't do allthe processes of life
|
|
|
|
What happens when the cell is to big?
|

|
|
|
|
What determines the shape of a cell?
|
function
|
|
|

Prokaryote?
|
Cell with out membrane bound organelle
|
|
|
|

|
Cells with membrane bound organelle
|
|
|
|

|
group of cells working together
|
|
|
|
organs?
|
group of tissues working together
|
|
|

Parts of Eukaryotic and Prokaryotic Cells?
|
Cell Membrane/Plasma
Cytoplasm Ribosomes |
|
|
|
Membrane?
|
The outer phospholipid boundary of a cell, found in all cells
|
|
|
|
Functions of cell membrane?
|
protection
keeps good stuff in keeps bad stuff out cellular identiy |
4
|
|
|
Selectively Permeable Membrane/
|
pick what passesthrough outer layer
|
|
|
|
How a selectively permeable membrane is supposed to work?
|
proteins have a 3d shape and 3d shape matches whatever its supposedto allow through the membrane
|
|
|
|
Parts of a cell membrane?
|
phospholipids,proteins,carbohydrates
|
3
|
|
|
Protein markers?
|
ID tags for the cells
|
|
|
|
Protein Pores?
|
Selective pathways across cellular membrane
|
|
|
|
Protein receptors?
|
proteins which recieve signals from other cells
|
|
|
|
Compadibility issues due to cellular ID tags
|
match blood type
match of marker proteins cut off part of immune system |
|
|
|
Fluid Mosaic Model of Cell membrane?
|
model of the cellmembrane incorporatingthe multi-facet nature of the cell and thefactitis a liquid
|
|
|
|
Phospholipid Bilayer/Lipid Bilayer
|
cell membrane has 2 layers of phospholipids
|
|
|
|
How do protein receptors work?
|
Receptor has 3D shape that matches chemical signal
|
|
|
|
Cytoplasm?
|
jellylike stuff inside of a cell
|
|
|
|
Cytoplasmic streaming?
|
movement of the cytoplasm inside cell
|
|
|
|
What cytoplasmic streaming accomplishes?
|
distributes food and waste throughout the cell and aids in cellular movement
|
|
|
|
Ribosomes? most what?
|
organelles without memebranes that make proteins, most numerous organelle in acell
|
|
|
|
Ribosomes in Prokaryotic cells are where?
|
scattered throughout cytoplasm
|
|
|
|
Ribosomes in Eukaryotic cells are where?
|
in cytoplasm or on the rough endoplasmic reticulum
|
|
|
|
Free Ribosomes? Bound Ribosomes?
|
Free: scatter throughout cytoplasm -make proteins that are used inside cell
Bound: bound to Rough Endoplasmic Reticulum - make proteins that are secreted out of cell |
|
