Presentation transcript. plant biology: germination unit 5 – plant anatomy, growth & function mr. tsigaridis. seed germination • seeds initially germinate as they absorb water, bursting the seed coat so the growing plant can produce energy • this starts a chain of chemical reactions which will result in the development of a plant embryo.
Ppt Plant Biology Germination Powerpoint Presentation Free Download 2) requirements for seed germination include water, gases, temperature, and light. there are two types of seed germination: epigeal and hypogeal. 3) seed germination involves three phases imbibition, a lag phase, and mobilization of food reserves. during these phases, stored resources like starch and proteins are broken down and utilized. 16. embryo the embryo is the baby plant, which emerges from the seed and germinates into a mature plant. the embryo consists of cotyledons or seed leaves or nurse leaves. they are fleshy, green, leaf like structures and provide nourishment to the growing embryo. it also consists of radicle or future root of the plant. it is the first to emerge out of the micropyle during germination and. Germination ppt final. germination is the growth of a plant contained within a seed; it results in the formation of the seedling, it is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radical and plumule. all fully developed seeds contain an embryo and in most plant species some store of food. Stages of germination • #3 – metabolic processes increase • swelling cells break seed coat • root tip emerges downward • stem shoot grows upward • shoot begins photosynthesis • root begins absorbing water and nutrients. conditions for germination • conditions have to be right for the new plant to survive • they include.
