BIOL 110 Study Guide - Final Guide: Pollen Tube, Indeterminate Growth, Sepal
Document Summary
Diploid (2n) anther meiosis haploid (1n) microspores pollen. Grain (2 nuclei) this is male gametophyte one nucleus is pollen tube other nuclei go through metosis for 2 haploid three haploid. Cells total : carpels, female, stigma, sticky, pollen lands on it from stamen (anther part) pollination, germinates, style, pollen tube grows through here, ovary, has an ovule. Diploid (2) ovule meiosis haploid megaspore mitosis. Three times 8 haploid nuclei in seven cells 1/7 is egg and. 1/7 is bigger because 2 nuclei all 7 cells is embryotic sac this is female gametophyte enclosed by ovary: produces egg cell, a bunch of carpels is a pistil. Imperfect flower = staminate (male) / carpellate or pistillate (female) = dioecious (ex. Plants with male on one part and female on other (ex. Seed: outer layer is maternal ovule tissue, embryotic root, the cotyledons are also called "seed leaves. , endosperm nutrients of embryo.
