Isoosmotic-two solution with same o; Hypoosmotic- solution that has a less negative o(more +) Turgor Pressure -hydraulic …

…bottom, 2 middle); megagametophyte = cell wall formation lead to 7-celled gametophyte with 8 nuclei = 3 cell at micropyle-1 egg/2 synergid cells; 3 at top-called antipodal; 2 center-produce endosperm. The anther's (microsporangia) microsporocyte produce microspores by meiosis-divide once then release. POLLINATION- transfer of pollen from anther to stigma. = In gymnosperm/angiosperm the sperm travels in pollen grains. 2 types; self-pollination (legumes, peas) and cross- pollination (wind, insect, animals and water). In wind pollinated flowers the stigma is sticky or featherlike. Word Count: 4332
