NEET BIOLOGY

Detailed explanation-1: -All multicellular organisms develop from a single cell which is the zygote.

Detailed explanation-2: -All multicellular organisms, from fungi to humans, started out life as single cell organisms. These cells were able to survive on their own for billions of years before aggregating together to form multicellular groups.

Detailed explanation-3: -A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).

Detailed explanation-4: -All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago, a new study seems to confirm. The study supports the widely held “universal common ancestor” theory first proposed by Charles Darwin more than 150 years ago.

Detailed explanation-5: -A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.
