    each process? Microsporogenesis produces our microspores. It occurs in the sporangia of the anther in flowers. Four haploid microspores are produced when the mother cell undergoes meiosis. Each microspore develops into a pollen grain. Megasporogenesis occurs in the sporangium of the ovule of a flower. After meiosis‚ the embryo sac is produced (egg‚ nucei‚ antipodal cells‚ synergids). 3. Draw and label all parts of a complete flower. Indicate the functions of the major parts.

    decolorized by mitochondria‚ then the percent transmittance of chloroplast suspensions would end up looking like a straight‚ horizontal line across the graph because photosynthesis would not occur without the chloroplasts. If DPIP was decolorized by both mitochondria and chloroplasts‚ then the percent transmittance of chloroplast suspensions would be a gradual increase‚ and the graph would be a line going up at a steady rate. The data I collected does not support my hypothesis because I said the rate

Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

    Meiosis is the separation of a diploid cell in which results in the production of four haploid daughter cells containing half the number of chromosomes that were found in the parent cells. For example‚ the starting number of chromosomes is 46‚ which are paired into groups of two making 23 pairs of chromosomes. The process of meiosis is broken down into two courses: meiosis I and meiosis II. Before the stage of meiosis‚ a cell must undergo a phase described as interphase. Interphase consists of three
