Introduction To differentiate between bacteria‚ fungi and yeast‚ we plant four different microbes in plates under the same environment for one week and compare the growth of the four microbes by macroscopic and microscopic observation. Meanwhile‚ the diversity of bacteria and fungi in humans‚ the environment and wood could be observed. In addition‚ the four substrates are cultured in two media‚ MEA and NA‚ under the same condition. Thus‚ how nutrients affect the growth of bacteria and fungi could

provides energy for the car to make it run. Centrioles within the cell can be compared to the parts of a car engine. The function of centrioles is to help with cell division in animal cells. Centrioles are mainly made up of protein strands called microtubules. The centrioles found within a cell can be compared to the engine parts of a car because parts in an engine need to be changed periodically much like how centrioles help duplicate the cell. Lysosome within a cell can be compared to something

female egg’. (News-medical‚ 2012). The neck of the sperm contains centrioles which form the structure of the flagella also known as the tail of the sperm. The flagellum creates movement in order to swim to the ovum. The flagellum is composed of microtubules‚ with proteins known as axoneme. Axoneme is the core of the flagella‚ it has two centrial filaments and is enclosed by nine other pairs which motor movement. The middle

A Survey of Eukaryotic Cells and Microorganisms HISTORY OF EUKARYOTES: 1. Evidence indicates that the first Eukaryotic cells first appeared on the earth approximately 2 billion years ago. Fossilized cells appear in shale sediments from China‚ Russia and Australia the date from 850-950 million years ago. 2. Biologists have discovered evidence to suggest that the eukaryotic cell evolved from prokaryotic organisms by a process of intracellular symbiosis. 3. Some of the organelles that
