CHAPTER 5: CELL DIVISION

CHAPTER 5: CELL DIVISION. Cells: Wear out after some time Get damaged Grow old naturally and die Therefore organisms need to produce new cells to : replace those cells that are worn out, damaged or dead Perpetuate their own species either by asexual or sexual reproduction.

Plant Life Cycles

Plant Life Cycles. Plant life cycles alternate between two cycles: Producing spores and producing gametes. Alternation of Generations. Sporophyte (diploid) Begins when sperm fertilizes egg (zygote) Diploid zygote divides by mitosis to create a mature sporophyte

Important features of gymnosperms

Important features of gymnosperms. Gymnosperms ( gymnos - naked, sperma = seed) are naked - seeded plants. These group of plants have ovules which are not enclosed and thus the seeds remain naked. Most of the gymnosperms are evergreen, woody perennials with shrubby or tree like habit.
