Document Summary
Irreversible increase in height, volume, weight, volume, or number in case of populations. Development: qualitative changes in body structure or function. Examples: development of organs, (organogenesis), achieving final shape and size (morphogenesis), Juvenile phase, adult phase (sexual maturity, flowering, senescence or physiological aging. ) Fu(cid:374)(cid:272)tio(cid:374): (cid:272)alled (cid:862)(cid:272)ell divisio(cid:374) hor(cid:373)o(cid:374)e(cid:863) (cid:271)e(cid:272)ause it pro(cid:373)otes (cid:272)ell divisio(cid:374) Fungi produces gibberellins that infect the rice plant and induce hyper elongated stems. Shoot and root show opposite response to gravity: shoots grow away from, and roots grow towards gravity. If we cut the apical meristem, the dormant lateral buds will grow into lateral shoots. Many small seeds need light signal after hydration to start germination. This ensures that germination occurs only when seed is close to the surface of the soil. If they germinate in the deeper layers of soil, they will run out of food material before they emerge and start making photosynthesis.
