Growth and differentiation are the two processes that makeup development. Knowing that the development of a mature plant from a zygote follows a precise and highly ordered sequence of events is both necessary and sufficient. A sophisticated body organization develops, which finally dies. The germination of seeds is the first step in the plant growth process. Seeds need favorable conditions to germinate and resume metabolic activity if they have been dormant for a while (under unfavorable conditions).<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Students will also learn about some of the elements that govern and control the various developmental processes in this chapter.
