Document Summary

Become more abundant when exposed to higher nutrient levels. Enhanced phytoplankton growth in a lack can have many negative consequences. Key principles of experimental design are: develop a hypothesis, tentative explanation for a well framed question, designing an experiment with controls, untreated microcosm, designing an experiment with replication, randomizing treatments. Daily care of microscope: wipe each lens with a kimwipe, turn off illumination and unplug cord. Total magnification: magnification of eyepiece x magnification of objective x magnification of binocular tube. Move in the direction opposite than the actual movement of the slide. Fibers that make up the paper are from wood. Wet mount: drop of water, place cover slide, no bubbles. Optical section: single plane of focus in an object. Cells contain dna, organelles and cytoplasm which are surround by a cell membrane (plants and fungi have a cell wall) Protozoans are unicellular, while plants and animals are multicellular. Multicellular; organized into different tissues: groups of cells that function together.
