BOTANY  Terms to know: Haploid: having a single set of chromosomes in each cell. Diploid: having two sets of chromosomes in each cell. Mitosis: cell division, which produces two genetically identical cells. Meiosis: reduction division, which produces four haploid reproductive cells.  Animals vs. Plants Plant Reproduction Animal Reproduction Alternation of No alternation of Life cycle generations generations Gametes Haploid gametes Haploid gametes Spores Haploid spores No spores Gametes made Haploid gametophyte, Diploid organism, by by by mitosis meiosis Spores made Diploid sporophyte, by No spores by meiosis Plant Reproduction  LEAF FORMS Simple – 1 petiole 1 leaf Compound – 1 petiole 2 or more leaves  PHYLLOTAXY leaf arrangement in stem LEAF VENATION  CHECK YOUR UNDERSTANDING Identify the leaf venation: Leaf 1 Leaf 2 Leaf 3 Identify the leaf venation: Leaf 4 Leaf 5 Leaf 6 LEAF MARGIN  CHECK YOUR UNDERSTANDING Identify the leaf margin: Leaf 1 Leaf 2 Leaf 3 Identify the leaf margin: Leaf 4 Leaf 6 Leaf 5 Identify the leaf margin: Leaf 7 Leaf 8 Identify the leaf margin: Leaf 10 Leaf 9 Flowers Flower Parts  Incomplete flowers Flowers are complete if they have all parts, and perfect if they have both male and female parts.
