eukaryote
"eu" means true- and remember that "kary" means nucleus, so in essence the word "eukaryote" means "true nucleus." are larger and much more complicated than prokaryotic cells.
Eukar1otic. cells
are • -10 times larger then prokaryotic cells • Evolved after prokaryotes • Are much more complex ... • contain a membrane bound nucleus • numerous other membrane bound organelles • Eukaryotic cells include all animal and plant cells ... basically if an organism is not a microbe (prokaryote) then its a Eukaryote. • Eukaryotic organisms can be unicellular or multicellular
two major types of cells
prokaryotic and eukaryotic
all plant cells are
eukaryotic
Plant cells
super super tough material in a cell wall is like I said made up of cellulose
Prokaryotic cells
the simplest and most ancient types of cells. They were the only form of life on Earth for billions of years before eventually giving rise to eukaryotic cells. cells are a lot smaller than eukaryotic cells and have a simpler structure. prokaryotic cells lack a nucleus. The name "prokaryote" actually gives you a hint about its structure. "kary" means "kernel" or "nucleus" and "pro" means before. Prokaryotes also have a cell wall that surrounds the plasma membrane. he composition of the cell wall depends on whether the cell is an archaean or a bacteria, but basically it consists of complex polysaccharides.
commonalities: Both prokaryotes and eukaryotes
• Have DNA as their genetic material • Have ribosomes • Have cytoplasm • Have a plasma membrane Now let's look at some of the ways they differ: • Prokaryotic cells are the oldest type of cell. They are small and relatively simple. Eukaryotic cells evolved from prokaryotic cells later. They are larger and much more complex internally. • Prokaryotes lack both a nucleus and membrane-bound organelles. Eukaryotic cells have a nucleus, and also contain organelles. • Prokaryotes are single-celled organisms. Eukaryotes can be either single-celled or multicellular. • And finally, the DNA of a prokaryote is usually organized as a single, circular chromosome, while the DNA of a eukaryote is organized as linear chromosomes..
