Question

Paragraph on Prokaryotic and Eukaryotic cells​

Answer 1

Explanation:

• Prokaryotic: These cells do not contain histone protein due to which chromatin has not been formed. Only the DNA sources are in the form of a chromosome. No other cover surrounds it. Therefore, there is no developed cell called nucleus.

• Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm.

• Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotes belong to the domain Eukaryota or Eukarya; their name comes from the Greek εὖ and κάρυον.

Answer 2

Prokarypotic Cells – Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm.

Eukaryotic Cells – Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotic cells have a membrane-bound nucleus. On the contrary, prokaryotic cells lack a true nucleus, i.e., they have no nuclear membrane. Unlike eukaryotic cells, the prokaryotic cells do not have mitochondria, chloroplast and endoplasmic reticulum.
