have identical DNA. Sometimes‚ plants are self-pollinated‚ producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots‚ which later sprouted new trees. When earthworms are cut in half‚ they regenerate the missing parts of their bodies‚ leading to two worms with the same set of genes. However‚ the ability to intentionally create a clone in the animal kingdom by working on the cellular

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

Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro

Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane‚ while osmosis is the process in which water molecules move passively from a region of higher water potential to a region of lower water potential through a differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium

Many different plant and animal species thrive in the rainforest environment‚ but it is the trees that define the way we see the rainforest. From the air‚ a rainforest looks like an enormous‚ green carpet. The canopy very rarely breaks‚ with no gaps between the trees. Beneath these trees‚ there are thousands of different types of plants. Living amongst the trees‚ vines‚ shrubs‚ ferns‚ and mosses are many different types of animals. These range from the smallest ant to the carnivorous (meat-eating)

The domestication of plants and animals lead to great change in the development and structuring of communities‚ as the hunter-gatherer lifestyle was slowly replaced by permanent settlements of farmers and villages. We can see that the communities varied greatly dependent on their local ecology‚ the resources available‚ and the time period within which their community was based. The road to agricultural way of life in the MIddle East is characterized by Four distinct stages. It was during the Kebaran

Thursday‚ October 4th‚ 2012 Tuesday‚ October 9th‚ 2012 Comparing Plant and Animal Cells Abstract The purpose of our lab was to have a better understanding of what are the differences between animal cells and plant cells. Although the cell is the basic unit in both living beings they are not completely alike. For that I have examined and compared human cheek cells to Elodea leaf cells. First‚ I’ve scraped the inside of my cheek with the end of a swab stick to collect the cells then I’ve prepared

desert is the home to many plant and animal wildlife. Of course‚ to survive the hot and dry conditions‚ these wildlife have to be specially adapted to capture as much food and water as possible to sustain themselves. In the desert‚ it can get as hot as over 30 degrees in the day and below 16 degrees at night! This project will further explore a few of the plants and animals‚ as well some of their adaptations.

Plant tissue culture is a widely used procedure in plant biology in which organism is planted from the explants of the living plants in a nutrient medium under aseptic conditions. There are both advantages and disadvantages of plant tissue culture. Advantages: 1. To produce many copies of the same plants then which may be used to produce plants with better flowers‚ odors‚ fruits or any other properties of the plants that are beneficial to the human beings. 2. To produce plants anytime we want
