the cell

QuestionAnswer
total magnification objective lens x eyepiece lens power
what is electron microscope used for to view cell ultrastructure
cell ultrastructure detail of cells/ cell structures as seen using an electron microscope
protoplasm all living matter in the cell (cell membrane and nucleus)
nucleus contains chromosomes made up of DNA and protein
cytoplasm living material in a cell outside the nucleus. composed of organelles and cytosol
cytosol liquid surrounding the organelles
What are cell walls made from cellulose - a structural carbohydrate
function of cell wall protection, support and strengthen cell. fully permeable
where is the cell membrane located immediately inside the cell wall
function of chloroplast photosynthesis
function of vacuole provide strength to cell ( pushed the cytoplasm out against cell wall - turgor pressure) allows for storage ( contains cell sap with a solution of salts and sugars)
what are cell membranes composed of phospholipids, proteins and marker antigens
phospholipids consist of a phosphate group and a lipid group. arranged into double layers in the membrane called bilayers. phosphate group (water loving) lipid group (water hating)
marker antigens proteins on the surface of the cell, allows cell to be identified as part of the body, so its not attacked by the body's immune system
functions of cell membranes selectively permeable (controls what enters and leaves the cell/organism) retains cell contents and recognizes molecules that touch it
structure of the nucleus has a double membrane contains nuclear pores making it selectively permeable contains DNA and protein (human cells mostly have 46 chromosomes)
chromatin chromosomes when cell is not dividing
function of nucleolus makes ribosomes (RNA)
Functions of nuclear structures controls the cell nuclear pores allow molecules in and out of the nucleus
