Which cell is the largest?
The largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm.
Which is the smallest cell in plant cell?
Answer. Smallest cell:-Duckweeds of the genus Wolffia are the world’s smallest flowering plants and measure only 300 µm by 600 µm and reach a mass of just 150 µg. The cells of this plant are smallest.
Who is the smallest cell?

Is acetabularia the largest plant cell?
Ovule of cycas is the largest cell among the multicellular plants. The unicellular marine alga Acetabularia, can reach upto 10 cm in height.
Which blood cell has the shortest lifespan?
Probably neutrophils (granulocytes) have the shortest lifespan of human cells, 4 hours or less. Neutrophils make up about 55–70% of our white blood cells. They are the part of our white blood cells that fight bacterial infections.
What is the shortest living cell in the human body?
As for the liver, the human body’s detoxifier, its cells’ lives are quite short – an adult human liver cell has a turnover time of 300 to 500 days. Cells lining the surface of the gut, known by other methods to last for only five days, are among the shortest-lived in the whole body.

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.
What is the smallest plant?
Watermeal (Wolffia spp.) is a member of the duckweed family (Lemnaceae), a family that contains some of the simplest flowering plants. There are various species of the genus Wolffia worldwide, all very small. The plant itself averages 1/42” long and 1/85” wide or about the size of one candy sprinkle.
What is the difference between plant cell and animal cell?
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
