Question

Deekshith said that “we can’t see a cell with naked eyes”. Is the statement true or false? Explain.

Answer 1

The basic structural and functional unit of life is cell. The organism can be unicellular, bicellular, and multicellular. Cells mainly consist of cell membranes, cytoplasm, nucleus, and organelles.

Complete answer: The range of the human eye is to see objects that have size 100 microns. Below 100 microns our naked eye can’t see the object. Our body cell size is 10 microns that mean we are unable to see cell with our naked eyes. But we are able to see an egg. An egg is also a cell and we are able to see an egg with our naked eye so if Deekshith said about body cells then the Deekshith statement is true but Deekshith said that we can’t see cells with the naked eye then it is false because we can see some cell with our naked like for example ostrich egg.

Additional Information:
Cells are divided into prokaryotes and eukaryotes. Prokaryote cells have not a well-defined nucleus and organelle membrane for example bacteria have prokaryotic cells. Eukaryote cells have a well-defined membrane of nucleus and organelle for example RBC, WBC.
The cell wall is the distinctive feature of some microorganisms and plants.
Ostrich cell is the largest single cell in the world.
Only Muscle cells have the ability to contract and relax that help in movement and locomotion.
A nerve cell is the longest cell that transfers the electrical signal from one part to another part of the body.

Note: Microscope invention is the main step towards the discovery of cells. The cell is discovered by Robert Hooke from the cork of bark with the help of a microscope.
