yes
multicellular organisms begin as a single cell.

Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
Living things begin with cells, which are the basic units of life. All organisms, from single-celled bacteria to complex multicellular organisms like plants and animals, are made up of one or more cells. These cells contain genetic material and are capable of carrying out essential life processes, such as metabolism, growth, and reproduction. Thus, the cell is fundamental to the structure and function of all living things.

Multicellular organisms begin as a single fertilized cell called a zygote. The zygote undergoes repeated rounds of cell division and specialization to form different cell types, ultimately developing into a multicellular organism. This process is known as embryogenesis.

Pioneer species, such as lichens and mosses, are typically the first organisms to colonize an area after primary disturbance. These hardy organisms can grow on barren surfaces and begin the process of ecosystem development by creating suitable conditions for other plants and animals.
Protists include unicellular, colonial and multicellular organisms Most protists are unicellular although (only one group) can be multicellular. There are types of algae, green algae known as Ulva, that are multicellular protists. They begin as colonies of unicellular protists known as Volvax, but the ones that break away are the multicellular version. The multicellular protists are without any specialized tissues. Protists used to be considered soley unicellular. Now that the molecular information has been redifined, protists are both unicellular and multicellular. .

Continental rifting will cause plants and animals to evolve due to their changing habitats. Plants and animals that become isolated will begin to diverge and change to fit into their new ecosystems.
