LESSON NO. 3 Levels of Organization Structure & Functions Flow of Energy Reproduction & Inheritance Evolution Regulation Adaptation Interaction with Environment Interacting System Biology and Society LESSON NO. 3  Identify the type of sexual and asexual reproduction in animals. Describe the different ways of how representative animals reproduce. Realize the importance of reproduction to maintain the continuity of life What's in the Word? continuation or preservation of a situation -Oxford dictionary Simple Organism reproduce through ASEXUAL REPRODUCTION - offspring comes from single parent and has the exact copy of the genes hence referred as Clones SEXUAL REPRODUCTION - in animals is the production of new living organisms by combining two gametes from different organism – one made producing motile gamete (sperm cell) that must fuse with the egg cell from a female organism. SEXUAL REPRODUCTION - in animals is the production of new living organisms by combining two gametes from different organism – one made producing motile gamete (sperm cell) that must fuse with the egg cell from a female organism.  LIFE SPAN The period from birth to the natural death of an organism is called its life span. Life span of an organism may be few minutes to several thousand years.  Life span of some organisms Organism Life span Fruit fly 1 day Butterfly 1-2 weeks Wheat plant 6 months Crow 15 years Dog 25 years Banana tree 25 years Crocodile 60 years Human 100 years Parrot 140 years Tortoise 100- 150 years Banyan tree 200 years ASEXUAL REPRODUCTION Kataka taka plant ASEXUAL REPRODUCTION FRAGMENTATION FRAGMENTATION FRAGMENTATION vs. REGENERATION BINARY FISSION Types of Binary Fission LONGITUDINAL Binary Fission TRANSVERSE Binary Fission IRREGULAR Binary Fission Budding PARTHENOGENESIS Zebra shark Komodo PARTHENOGENESIS Aphids Honey bee BIO TASK # 2  LIVING ORGANISM DESCRIPTION TYPES 1.
