multicellular diploid form‚ the sporophyte‚ and a multicellular haploid form‚ the gametophyte. <br> <br>Meiosis in mosses produces haploid spores. This process occurs in a sporangium‚ a capsule in fungi and plants in which meiosis takes place and haploid spores develop. After fertilization‚ the sporophyte zygote grows out of the parent gametophyte. At the end of this stalk is the sporangium. Meiosis occurs and the haploid spores disperse. In ferns‚ the mature sporophyte (2N) has small spots on the undersides

Study the diagram of the human life cycle and indicate where in the human body mitosis and meiosis occur; which cells are the result of meiosis and mitosis; and which cells are haploid and which ones diploid. 5. Distinguish between sexual and asexual reproduction. 6. What type of cell results from meiosis? List function and chromosomal number. 7. Meiosis consists of two divisions.

Lab 8: Mitosis‚ Meiosis and the Cell Cycle . header Purpose: This activity is designed to familiarize you with the phases of mitosis and meiosis and compare these processes in a comparison chart. This activity will be three parts. For parts I and II‚ please scan your labeled work. Preparation: There is no preparation or materials needed for this activity. You will simply need access to a scanner to submit your work. Procedure Part 1: For this portion of the laboratory‚ please sketch a cell

Genetics Paper Each human in the world is created both separate and unique. Although members of a family may possess common traits‚ each member has their own individuality. Genetics allows for a creation of a unique individual. Chromosomes‚ meiosis‚ and fertilization are essential parts of genetics vital to the development of a distinct organism. The effect of each allows for a world in which no human is equal. To begin‚ chromosomes in genetics plays a key role in individuality. In genetics

Haploid (N) is half of the diploid num-ber. In interphase‚ chromosomes are replicated and align in homologous pairs. Each pair contains a maternal and paternal homologue inherited from the previous genera-tion. An important consequence of meiosis is that the genomes are mixed and

PROKARYOTES ◦ Binary Fission Prokaryotic chromosome contains mostly DNA and some associated proteins Asexual reproduction requires a single parent; offspring are genetically identical to parent. EUKARYOTES Meiosis and Mitosis MEIOSIS Meiosis is essential for sexual reproduction and therefore occurs in all eukaryotes MITOSIS process in which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two daughter nuclei
