Who discovered the cell?
Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.
Which blood cell is smallest in size?
Platelets (thrombocytes) The blood platelets are the smallest cells of the blood, averaging about 2 to 4 μm in diameter. Although much more numerous (150,000 to 400,000 per cubic millimetre) than the white cells, they occupy a much smaller fraction of the volume of the blood because of their relatively minute size.

Platelets are the smallest of the three major types of blood cells. Platelets are only about 20% of the diameter of red blood cells. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume.
Is a virus a cell?
Viruses do not have cells. They have a protein coat that protects their genetic material (either DNA or RNA). But they do not have a cell membrane or other organelles (for example, ribosomes or mitochondria) that cells have. Living things reproduce.
Is virus smaller than Pplo?
Viroids, virusoids and prions are subviral pathogens smaller than the virus. Viroids disease-causing free RNA without nucleoprotein, virusoids are small RNAs inside the protein coat, and prions are made up of proteins only. So, the correct answer is ‘(c) PPLO’.
