Question

Prokaryotic and Eukaryotic Cells

prepare a table or diagram that compares the components and characteristics of prokaryotic and eukaryotic cells. Be sure to include both (1)similarities- characteristics in common and (2) differences- characteristics unique to each cell type.

Answer 1

Characteristics	Prokaryotes	Eukaryotes
1)Nucleus	Diffuse	Well defined
2)Nuclear membrane	Absent	Present
3)Nucleolus	Absent	Present
4)Cell division	Binary fission	Mitosis,Meiosis
5)Chromosome	One in number,Shape is circular	Many chromosomes, linear in shape
6)Extrachromosomal DNA	Found in plasmid	Found in mitochondria
7)Cell membrane	Does not contain sterols except in mycoplasma	Conatins sterols
8)Cellular organelles like mitochondria,etc	Absent(Except ribosomes)	Present
9)Ribosomes	70S	80S
10)Site of respiration	Mesosome	Mitochondria

similarities in prokaryotic and eukaryotic cells:

• Presence of DNA(genetic material) and RNA is common.
• They both have a cell membrane covering them.
• Both of them have ribosomes(protein factory of the cell).
• Both these organisms have a fluid-like matrix called the cytoplasm.
• Both have a cytoskeleton within the cell to maintain structural integrity.
