Plant Reproduction: Seedless Plants


Review what are the different types of plant reproduction
Review: What are the different types of plant reproduction?

  • Sexual reproduction

    • Are these cells haploid or diploid?

  • Asexual reproduction

    • Are these cells haploid or diploid?

  • Today we are learning about reproduction in seedless plants by SPORES

    • Which type of reproduction produces spores?

      • SEXUAL REPRODUCTION


What types of plants are seedless
What types of plants are seedless?

  • Ferns and moss

  • Found in cool, moist, shaded areas in the forest

  • Usually grow near the ground

  • Reproduce sexually by SPORES


Life cycles of seedless plants ferns and moss
Life Cycles of Seedless Plants (Ferns and Moss)

  • Plants reproduce and have a life cycle

    • Ex: one stage is reproduction

  • Plants have a life cycle with 2 stages

    • GAMETOPHYTE STAGE

      • Gametes = sex cells, phyte = plant

    • SPOROPHYTE STAGE

      • Sporo = spores, phyte = plant


Life cycles plant stages
Life Cycles: Plant Stages

  • GAMETOPHYTE stage

    • Reproduction: where cells go through the process of meiosis

    • HAPLOID cells (HALF the number of chromosomes)

  • SPOROPHYTE stage

    • Fertilization: when haploid cells combine

    • DIPLOID cells (DOUBLE the number of chromosomes)


Life cycles plant stages1
Life Cycles: Plant Stages

  • When a plant’s life cycle alternates (changes) between gametophyte and sporophyte stages, this is called:

    ALTERNATION OF GENERATIONS

  • This means that the plant changes between the two stages:

    • Sporophytes produce spores

    • When the spores mature, they are called gametophytes because they produce the sex cells (gametes) and once the gametes combine, produce the sporophyte again!


Life cycles plant stages2
Life Cycles: Plant Stages

  • In ferns, spores are produced in structures called SORI

  • These are found on the underside of leaves

    • Red – brown or black colored bumps

    • These cells have gone through meiosis to form spores and each one can grow into a new plant!
