Problem Set 1 Solutions: Chapters 1 1 Cell sizes: E. coli is a cylindrical bacteria with 1 M wide and 2 M long. Liver cells are approximately spherical with a diameter of 20 M. Plant palisade cells are cylinders 20 M wide and 35 M long. A) Calculate the volumes of each cells? A) Since E.Coli is cylindrical Volume of a cylinder = r2h‚ where r is half of bacterial width/diameter = 1M/2 = 0.5M and h is the length of the bacteria

microorganism survival largely related to the suspended solids in the water. A disinfectant is nearly always included in treatment plants of any size. Pinang Tunggal water treatment plant produce 227‚000 cubic meter per day of treated water. The source of raw water for the plants is from the Muda Dam through the Muda River. Their main role of Pinang Tunggal water treatment plant is to inactivate any remaining bacteria as the final unit of treatment and‚ more importantly to provide a residual disinfectant

Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

Legend of the Banana Plant In the early days when the world was new‚ spirits and ghosts lurked everywhere. They lived in gloomy caves‚ they hid in anthills and tree trunks they frolicked in nooks and corners under the houses. In the dark‚ sometimes their tiny voices could be heard dimly‚ or their ghostly presence be felt. But they were never seen. It was during these days of phantoms and unseen spirits that a young and beautiful girl lived. Her name was Raya‚ and she was a girl bold and daring

http://newmetode.Sharestiforp.com Plant tissue culture is a collection of techniques used to maintain or grow plant cells‚ tissues or organs under sterile conditions on a nutrient culture medium of known composition. Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation‚ including: • The production of exact copies of plants that produce particularly

The C4 & CAM Pathway Many plant species that evolved in hot‚ dry climates fix carbon through alternative pathways. Under hot and dry conditions‚ plants can rapidly lose water to the air through small pores called stomata. Stomata (singular‚ stoma)‚ are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata are

A plants volatile organic compound (VOC) composition is the hand that swats unwanted visitors‚ welcomes visitation from much needed pollinators‚ and the substantial determinant in a plants identity and overall evolutionary fitness within the plant community. Understanding the mechanics of volatile formation is essential in interpreting their importance in plant life‚ and in plant-animal interactions. A huge allocation of energy is assumed to be given to the production of volatiles‚ and is therefore

Transgenic Animals and Plants What is a transgenic animal/plant? A transgenic animal or plant is one that has a foreign gene (called a "transgene") inserted into its DNA. Transgenic animals and plants are sometimes called "genetically modified organisms" or GMO ’s for short. What is a transgene? A transgene is the foreign gene that has been moved from one organism into a new organism by genetic engineering. For example‚ a bacterial gene that is inserted into a plant ’s DNA would be a transgene
