Question

Is there a relationship between the size of an organism and its life span? Give two examples in support of your answer.

Answer 1

Different types of cells, of various shapes and sizes, make up living organisms. The shape of a single-celled organism differs from that of another single-celled organism. There are many different types of cells in a multicellular organism. Some are long and some are short; some are circular and others are oval.

Complete answer:
Cells vary in shape and size depending on their functions and composition. A nerve cell, for example, is long and branched and is responsible for signal transmission throughout our bodies, whereas a muscle cell is small and spindle-shaped and is responsible for movement.
In the case of an animal cell, the shape can be classified as round (spherical) or irregular. Plant cells are more rigid and rectangular in shape than animal cells. A cell can be as small as 0.0001 mm in size (mycoplasma) or as large as six to twelve inches in diameter (Caulerpa taxifolia).
Unicellular organisms, like bacteria, are usually microscopic. A single cell, however, such as an egg, is large enough to touch. They all contain the same organelles and help us perform our daily activities efficiently, whether they are regular or irregular in shape.
A person's, creature's, or animal's life span is defined as the amount of time between birth and death. The 80 years between birth and death that you may live is an example of life span.
There is no correlation between an organism's size and its lifespan. Both the mango and peepal trees, for example, are similar in size, but the mango tree has a much shorter life span than the peepal tree. A tortoise is much smaller than an elephant, and it lives for 80-120 years, compared to 48-60 years for an elephant.
Thus, Life span cannot essentially be related to their sizes. It'll be a misconcept to mention smaller organism-short era or larger organism-long era. Most eras have the most range of years survived or the best age reached by any member of a species.

Note:
Greenland sharks have the longest known lifespan of any vertebrate species. A study published in 2016 examined 28 specimens and determined that the oldest of the animals sampled had lived for about 392 120 years using radiocarbon dating (a minimum of 272 years and a maximum of 512 years).
