The normal examine of plants may be the science of botany.[123] Fundamental Organic exploration has typically employed plants as its design organisms. In genetics, the breeding of pea plants allowed Gregor Mendel to derive The fundamental regulations governing inheritance,[124] and assessment of chromosomes in maize allowed Barbara McClintock to reveal their link to inherited features.[one hundred twenty five] The plant Arabidopsis thaliana is Employed in laboratories like a product organism to understand how genes Management The expansion and growth of plant structures.
