1. Zygote Development: Dividing tissue divides to form sperm and egg. A zygote is formed by the union of sperm and egg. A zygote is a type of dividing tissue and is the first cell in an organism.
2. Embryo Development: The zygote divides repeatedly to form a multicellular embryo. Embryo is composed of dividing tissue and dividing cells. It is an important stage in the body formation of organisms.
3. Seedling Development: The embryo divides repeatedly to form a seedling plant. Seedlings have roots, stems and leaves.
4. Development of complete plant: The dividing tissue of the root, stem and leaves of the seedling plant divides repeatedly to form a complete plant. The dividing tissue of the whole plant divides to form different organs.
