Title- Protista Lab Concept- the concept of this lab was to explore what is in the pond water as living organisms and try to identify what it is. Some types of Protista are multi-cellular like giant kelp. Although they look much like plants‚ multi-cellular protists lack specialized tissues. Being eukaryotes‚ they have a membrane-bound true nucleus with linear chromosomes‚ and they have membrane-bound organelles. The kingdom Protista contains all eukaryotes that are not plants‚ animals‚ or fungi

are classified using a variety of characteristics including morphology‚ behavior‚ and molecular similarities. The classification system is based on evolutionary relationships so with each addition of new information the classification of specific organisms may change. This is particularly true of the bacteria‚ protist‚ and fungi kingdoms. Understanding these groups is essential due to their diversity and importance to life on Earth. __________________________________________________________________________

Biotechnology Biotechnology are genetic modifications referring to “altering the genetic trait of a living organism by using recombinant deoxyribonucleic acid (DNA) technology to transfer one or more genes from one organism to another by crossing biological species.”[65] New developments in molecular and cell biology allow scientists to modify foods by the identification‚ copying‚ and insertion of genes into plants. It can whether be a good or bad thing depending on a lot of personal

1a. What are the two goals of systematics? The goal of systematics is to organize living things into groups that have biological meaning. (Taxa or Taxon) 1b. Why do common names of organisms – like daisy or mountain lion – often cause problems for scientists? The common names of organism often cause problems for scientist because common names can change meaning among languages and from place to place. 1c.

among the Different Components of the Ecosystem I. Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population‚ community‚ and ecosystem ecology although it also includes a wide variety of fields. Both the living (biotic) and the

creature to another. This is called “genetic engineering.” Genetic engineering also refers to the artificial modification of the genetic code of any living organism. Genetic engineering changes the original physical nature of the organism‚ sometimes in ways that would never occur in nature. Genes from one organism are inserted in another organism‚ most often across natural species boundaries. Some of the effects become known‚ but most do not. There are some examples of genetic engineering that have

of life”(Louis Schwartzberg). Across the Earth‚ the main reason why cell division is so that organism can make more copies of the cells. Reproduction is the process of making offspring that are able to survive in the environment they are born into. There are two major forms of reproduction‚ which are asexual reproduction and sexual reproduction. Sexual reproduction is the production of new living organism by combining genetic information from two individuals of different sexes (an egg and sperm cell)

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
