Please take out your science journal and outcomes and turn in any missing work to the WIRE basket Thank you Asexual Reproduction Review Happens in almost all cells Somatic cells 1 parent cell. Chapter 12. Outline. Introduction. Asexual. Sexual Reproduction. The Phases of Meiosis. Division I. Division II. Alternation . of Generations. Introduction. Asexual . Reproduction . - . p. roduction . Meiosis. Meiosis is the cell division which produces the . sex cells . or . gametes. .. Meiosis occurs in the cells of the . reproductive organs. :. Sperm cells – testes. Ova (eggs) – ovaries. Pollen - anthers. Sexual Life Cycles. modes of reproduction. diploid/haploid and meiosis. meiosis I and meiosis II phases. key differences between mitosis and meiosis. variation in position of meiosis in life cycles. why sex?. ch. : 7. Sexual or Asexual. Asexual – involves a single parent organism and produces off-spring or daughter cells that are clones. Sexual Reproduction – involves genetic contribution in the form of gametes from two sources. Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:. Differentiate between the process of mitosis and meiosis. Demonstrate the movement of chromosomes throughout meiosis. Analyze how meiosis leads to genetic variation. Chapter . 11.

Meiosis Practice Test. Answer the following questions on the back of your review sheet.. Test Tomorrow!!!!!!!. Which of the following is an advantage of sexual reproduction over asexual reproduction?. I. Sexual reproduction is more rapid and less complicated.. II. Sexual reproduction results in more diversity.. Vocabulary. Somatic Cell. Gamete. Homologous Chromosomes. Diploid Cells ( 2n ). Haploid Cells ( n ). Normal body cell. Sex cell – sperm or egg. Matching pairs of chromosomes. Cells that have homologous chromosomes (somatic cells). Cell division / Asexual reproduction. Mitosis. produce cells with same information. identical daughter cells. exact copies. clones. same amount of DNA . same number of chromosomes. same genetic information. Let’s Review!. The cell cycle is when . a cell makes a copy of itself . for:. Growth, Repair, Replacement. BODY (autosomal/somatic) cells reproduce . by . mitosis. s. ome . organisms . do also, . but we will talk about that . Defined. : Gametes from two separate parents unite. Meiosis: Diploid (2n) to haploid (n) cells . Mechanism that allows for . genetic diversity. Many eukaryotes reproduce in this manner. Plants, animals and fungi. In asexual reproduction, a single individual gives rise to offspring that are identical to itself and . others [MITOSIS]. Bacteria reproduce asexually. Most plants and some simple animals can reproduce both asexually and .
