clasification based on celluarity.pptx

1. Prokaryotic cell

2. Eukaryotic cell

3. Prokaryotes Eukaryotes
Small size 1-10 micro meter Size range is 5 – 100 micro meter
DNA consists of non histone protein DNA complexed with histone and non
histone proteins in chromozomes
DNA found in a region called nucloid not
surrounded by membrane
DNA lies in nucleus surrounded by
membranous envelope
Membrane bound organelles like
mitochondria and chloroplasts are absent
Membrane bound organelles are found
Cell division is through fission or budding,
no mitosis
Cell division through mitosis and meiosis
Cytoskeleton absent Cytoskeleton like microtubules and actin
filament present
Intracellular movement is not seen Shows Intracellular movement like,
cytoplasmic streaming

4. Autotrophs Heterotroph lithotropes
Produces their own
food hence called
producers
Depends on other
organisms for their
food hence called
consumers
Use inorganic
substrate (usually
minerals) to obtain
their food
Either photosynthetic
or chemosynthetic
Various types present
like holozoic, parasitic,
saprotrophic and
symbiotic
They are usually
chemosynthetic
Plants, algae Animals, insects, birds Sulphur bacteria,
Hydrogen bacteria
