Structure and function of a cell - Coggle Diagram
Structure and function of a cell
microscopes
Electron Microscope (EM)
Transmission Electron Microscope (TEM)
beams electrons THROUGH subject
Scanning Electron Microscope (SEM)
scans electrons ACROSS subject
Light Microscope (LM)
simple light microscopes
uses one lens
compound light microscope
uses multiples lenses
used to see what the naked eye cannot
functions
magnification
real size vs specimen image
contrast
brightness of background vs specimen
resolution
decipher between objects; clarity
all cells have:
cytosol
the interior of any cell
cell membrane
chromosomes
ribosomes
protein synthesis
Prokaryotic
no membrane bound organelles
simple
small
only Bacteria and Archaea
Eukaryotic
has membrane bound organelles
nucleus
contains most of the genes in the eukaryotic cell
nucleolis
ribosomal RNA is synthesized here
transported to the cytoplasm via nuclear pores
large
complex
plasma membrane
selective barrier that allows passage of enough oxygen, nutrients, and wastes to service the entire cell
made of hydrophilic and hydrophobic parts of phospholipids
vesicles
transports substances
vacuoles are large vesicles (plants have large vacuoles)
endoplasmic reticulum
transport system
rough reticulum
has ribosomes
smooth reticulum
no ribosomes
Golgi apparatus
receiving and shipping center of the cell
lyosomes
digest macromolecules
mitochondria
mainly for cellular respiration
chloroplasts
mainly for photosynthesis
cytoskeleton
organizes structures and activities in the cell
