1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.

Elliot Griffin Environmental Science Final Opinion Paper Should DDT Be Banned Worldwide? First synthesized in 1874‚ DDT’s insecticidal properties were not discovered until 1939. In the second half of World War II‚ it was used with great effect among both military and civilian populations to control mosquitoes spreading malaria and lice transmitting typhus‚ resulting in dramatic reductions in the incidence of both diseases. The Swiss chemist Hermann Müller of Geigy Pharmaceutical

1. BIOLOGICAL CLASSIFICATION Aristotle’s classification - Aristotle was the earliest to attempt a more scientific basis for classification of organisms. - He classified plants into trees‚ shrubs & herbs and animals into two groups‚ those which had red blood and those that did not. Two-kingdom classification - In Linnaeus’ time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes

and meiofauna‚ protozoa are an important food source for microinvertebrates. Thus‚ the ecological role of protozoa in the transfer of bacterial and algal production to successive trophic levels is important. Protozoa such as the malaria parasites (Plasmodium spp.)‚ trypanosomes and leishmania are also important as parasites and symbionts of multicellular animals. Some protozoa have life stages alternating between proliferative stages (e.g. trophozoites) and dormant cysts. As
