What is Reproduction? . It occurs when organisms multiply, or produce offspring.. Sexual reproduction occurs when a female gamete and a male gamete unite.. Asexual reproduction doesn’t involve gametes. (ex. Simple cell division). The process of making new individuals (offspring) from existing individuals (parents).. ASEXUAL REPRODUCTION. :.

Sexual or Asexual. Asexual – involves a single parent organism and produces off-spring or daughter cells that are clones. Sexual Reproduction – involves genetic contribution in the form of gametes from two sources. Life Cycle. Life Cycle. – the development of an organism from fertilization to birth, growth, reproduction, and death.. The life cycle of every organism has these 4 main stages. 1. .

In asexual reproduction, one individual produces offspring that are genetically identical to itself. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction.. Essential idea: . The idea of discreteness that we met in the atomic world continues to exist in the nuclear world as well.. Nature of science: . (1) Theoretical advances and inspiration: Progress in atomic, nuclear and particle physics often came from theoretical advances and strokes of inspiration. (2) Advances in instrumentation: New ways of detecting subatomic particles due to advances in electronic technology were also crucial. (3) Modern computing power: (4) Finally, the analysis of the data gathered in modern particle detectors in particle accelerator experiments would be impossible without modern computing power..
