types of cells

Cells can be categorized into two main types: eukaryotes and prokaryotes. Eukaryotic cells include those found in plants, animals, protists, and fungi. Plant cells have a cell wall and chloroplasts, which are crucial for photosynthesis.

prokaryote

Archaebacteria
the presence of characteristic tRNAs and ribosomal RNAs and the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat
Archaeoglobus veneficus. Archaeoglobus profundus
Eubacteria
Streptococcus pneumoniae and Yersinia pestis
as characterized by the lack of a membrane-enclosed nucleus, predominantly unicellular, with DNA in single circular chromosome, and have peptidoglycan on cell wall when present. They include most of the familiar bacteria of medical and economic importance such as E.

eukaryote

Fungus
yeast and sac fungi
nucleus are enclosed in membranes. and they reproduce by spores
Protist
may contain a single nucleus or many nuclei they range in size from microscopic to 1 thousand meters in area
brown and red algea
Plants
has a cell wall and has chloroplast
sun flower dandelion
Animals
Subtopic
panther,dog,chicken
they dont have a cell wall. they are also suronded by plasma membrain
