SEXUAL & ASEXUAL REPRODUCTION 2026

Sexual & Asexual Reproduction Sexual: Propagation is by seed Asexual: Propagation is the increase of plants by vegetative methods.

Sexual & Asexual Reproduction Advantages more economical easier longer storage time

Sexual & Asexual Reproduction Disadvantages do not breed true slow growth do not produce viable seeds

Sexual & Asexual Reproduction Seedlings of different species are used as Rootstocks for many tree species Used for plant breeding, make new traits

Sexual & Asexual Reproduction Where do seeds come from? Flowers Male parts of the flower (stamen) filament and anther Female parts of flower (Pistil) stigma, style, and ovary

Sexual & Asexual Reproduction How does pollen grains fertilize the ovules? Pollen grains are carried by wind, water, or animals Pollen lands on stigma, pollen tubels grow toward ovary Fertilization happens in ovary Embryo is formed

Sexual & Asexual Reproduction Embryo grows outward and forms fruit or seed

Sexual & Asexual Reproduction Vegetative reproduction is asexual a= without Three types of cuttings: Tip cutting Leaf section, leaf petiole, or cutting veins Cutting of roots

Sexual & Asexual Reproduction Other Methods: Layering Separations Divisions Grafting
