Reproduction There are two types: Asexual only involves one parent which produces identical offspring (clone of parent) Sexual two parents (male/female) produce similar but not identical offspring. Sexual reproduction involves male and female gametes (gametes are sex cells). Disadvantages Advantages Must find a partner Produces variation in offspring Takes longer More likely to produce offspring which can survive if changes occur All offspring are identical and so susceptible to disease Fast Mutations of parents will also be seen in offspring No need for partner Sexual Asexual Examples of Asexual reproduction 1. Binary Fission e.g. Bacteria Two identical daughter bacterium Parent bacterium e.g. Yeast Budding Newly budded yeast cell 2. Spore production Millions of identical spores e.g. Fungi Each spore develops into genetically identical fungus 3. Plants (a) Runners e.g. spider plant Runner (withers away after clone is established) Original plant (b) New identical plant Rhizomes e.g. nettles Rhizome Original (underground runner) plant (c) Bulbs/Tubers New bulbs form and old one withers Old plant dies. Two new bulbs/tubers produce two identical plants
