4 structural features of organisms
Plasma membrane, Cytoplasm, Dna, Ribosomes
Organisms lacking membrane bound nucleus
Prokaryotes
Outside of plasma membrane
cell wall
What is the cell wall composed of
Polysaccharide and Amino Acids
If there is no organisms in pond is it healthy?
No
What microscopy uses molecules to emit absorbed light
fluorescent
subtype of microscopy that focuses on thin planes, uses computer to make 3D images
Confocal Laser Scanning microscopy, fluorescent
What type of microscopy is TEM and SEM
Electron microscopy
What does electron microscopy use?
high beam electrons
What does electron microscopy provide?
Higher resolution
What microscopy would you use for hairs on a bee?
SEM
What electron microscopy used for SER in liver cell?
TEM
What structural features distinguish eukaryotic from prokaryotic
Membrane bound organelles, Nucleus, some unicellular some not, larger
Prokaryotic bacteria part of a group of photosynthetic bacteria
Cyanobacteria
