Summary Introduction
Introduction:
Plant embryogenesis is a mechanism through which the plant generates an embryo through asymmetric type of cell division from a fertilized ovule. Embryogenesis occurs through the differentiation of the undifferentiated set of cells into organs and tissues. The formation of the leaf is not included in the embryogenesis.

Seeds have four layers of protective tissue, the seed coat, that improve survival by providing more protection from environmental stresses. b. The reduced gametophytes of seed plants are nurtured by sporophytes and protected from stress, such as drought conditions and UV radiation. c. Seed germination is solely mediated by water during episodes of heavy rain. d. Pollen grains, with walls containing sporopollenin, deter herbivores.

- During double fertilization, one sperm will unite with the egg, forming a zygote. As mentioned in the lecture, a generative cell divides to form two sperm. How is the second sperm used during the process of double fertilization? 00 00 It fertilizes the flower by landing directly on the stigma, which is the sticky surface found above a flower's style and ovary. This depends on the type of plant. Land plants will allocate the sperm that is not united with the egg to the formation of different tissues through mitosis and cytokinesis. It forms a triploid cell by fusing with polar nuclei. This cell then divides and develops endosperm tissue. Since it was not the sperm to fuse with the polar nuclei, the sperm cell will degenerate.arrow_forwardPlant development is influenced by: A. quality of light only B. quality and quantity of light C. quality and duration of light D. quality, quantity and duration of lightarrow_forwardThe term hypocotyl refers to the portion of the embryonic stem that is located below the attachment of the cotyledons.
