What are Cilia? The word cilia is derived from the Latin word cili which means eyelash. In the Latin word, Flagella means little whip. They are microscopic which can’t be … Read more
Osmosis Definition Osmosis is a biophysical process occurring commonly in biological systems where solvent molecules move across a semi-permeable membrane towards a region of high solute concentration. Figure: Osmosis. Image … Read more
What are Centrioles and Basal Bodies? In some eukaryotic cells, near the nucleus, there is the presence of two cylindrical structures. They are rod-shaped and microtubular. They are known as … Read more
