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

STEM CELL RESEARCH AND THERAPYAND ITS IMPACTS ON SOCIETY Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic‚ adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral‚ ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must be analyzed is the

This House would ban animal testing In this debate testing should be defined as all testing including‚ medical research‚ cosmetics‚ toxicology‚ and psychology research where animals are used in any part of an experiment. An animal could sensibly be defined as vertebrates. With this exception of cephalopods‚ no invertebrates have any legal standing in any country so far as I am aware‚ and it would be hard to construct a case for any invertebrates having moral rights. The ban should be defined as

also anchor the plant. Some roots have mycorrhizae‚ which increase the surface area and therefore increase the absorption. The endodermis‚ which is the innermost layer of cells in the root cortex‚ surrounds the vascular cylinder. It is the passage of minerals from the cortex into the vascular tissue. The stem has a system of nodes where leaves are attached. They have a waxy coating (epidermis) that prevents water loss. The stem and the roots are the 2 main axes in a vascular plant. Fluids are transported

though a cell is the basic unit of an organism it can be pretty complex inside of one. So why don’t we try and make it a little simpler by comparing it to something we’re all more comfortable with? Take Disneyland for example! Everyone is familiar with Disneyland and how it works. Let’s see just how similar these two can be. First‚ would be the entrance gate. The entrance gate could be our cytoplasm. Cytoplasm is the jelly-like fluid that fills a cell and inside is all the other cell organelles

allow cell phones to be sold without pre-market testing. The rationale‚ known as the “low power exclusion‚” distinguished cell phones from dangerous microwave ovens based on the amount of power used to push the microwaves. At that time‚ the only health effect seen from microwaves involved high power strong enough to heat human tissue. The pressure worked‚ and cell phones were exempted from any type of regulatory oversight‚ an exemption that continues today. An eager public grabbed up the cell phones

Engineering in Plants In the 1920’s‚ a man named Henry Wallace founded a company called “The Hi-Bred Corn Company.” He began selecting corn plants that flourished in certain aspects and bred them with other prosperous plants to make a hybrid. After pollenating the female silk of one plant with the pollen of another; the resulting offspring displayed both traits. This idea of ‘selective breeding’ would go on to become the norm in that era of agriculture because it produced bigger and better plants. Because

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
