Worksheet 2- Brittani Wright 1. a) Define a cell. A cell is the basic unit of life b) What is a unicellular organism? An organism that consists of only one cell c) Can a cell be multicellular? No because a cell is the smallest unit of life‚ cells can however join together to start forming something else 2. a) What is a difference between prokaryotic and eukaryotic cells? b) What is one significant similarity? Prokaryotic cells do not have a neucleus and Eukaryotic cells do have a nucleus

is a novel coronavirus with some unusual properties. One of the characteristics of SARS is its ability to grow in Vero cells. “In these cells‚ virus infection results in a cytopathic effect and budding of coronavirus-like particles from the endoplasmic reticulum within infected cells.” SARS has 29‚700 nucleotides sequences that’s has been found by serological (antigenic) investigations. The sequence appears to be typical for

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

A Journey into the Cell In Oulu‚ Finland a scientist by the name of George S. Fizzler was starting his new experiment. His new experiment dealt with shrinking things and seeing how other things looked like when shrunken down. This week he was shrinking a submarine so he could go into a living organisms cell. He was very fascinated with how the body worked and how cells work their “magic”. In order to do this experiment he is going to need some help from his friend Gary Bangelshrine and his cat

Chapter 2 IB Biology 2.1 Cell Theory 2.1.1 Outline the cell theory (2). • All organisms are composed of one or more cells • Cells are the smallest units of life • All cells come from preexisting cells • TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms • Exception: muscle cells- more than 1 nucleus‚ very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single
