TYPES OF CELLS
TYPES OF CELLS ➡️There are two types of cells (on the basis of structural form ) I) Prokaryotic Cells II) Eukaryotic Cells I) Prokaryotic cells ➡️It is primitive(साधारण) and incomplete cells. ➡️It is small in size (1 - 10mm). ➡️Nucleus is absent. ➡️Nuclear region or nucleiod is not surrounded by a nuclear membrane. ➡️It has single chromosome*. ➡️Nucleolus* is absent. ➡️Membrane bound cell organelles are absent. ➡️Cell division takes place by fission or budding (no mitosis). ➡️It consists of a single membrane - a. The plasma membrane or Cell membrane ➡️It is Unicellular organisms. ➡️DNA* is not associated (रिश्तेदार/जुड़ा हुआ ) with protein. Note point :- ➡️*Nucleoid - The undefined nuclear region in cytoplasm is called nucleoid(). ➡️DNA- Deoxyribonucleic acid ➡️A polymeric nucleic acid. ➡️RNA - Ribonucleic acid ; polymeric nucleic acid. Fig. No-1 II) Eukaryotic Cells ➡️Eukaryotic (Eu= good or well ;karyon=nucleus) ➡️It is lar
