Circa 1284= Italian‚ Salvino D’ Armante is credited inventing the first bearable eye glass. 1590= two dutch eye glass makers‚ Zaccharias Janssen and Hans Janssen experimented with multiple lenses. 1665= English Physicist‚ Robert Hooke looked at a silver of cork through a microscope lens and noticed some “pores” or “cells”. 1674= Anton Van Leeuwenhoek built

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

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)

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

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.

Elephant An elephant is the biggest living animal on land. It is quite huge in size. It is usually black or grey in color. Elephants have four legs‚ a long trunk and two white tusks near their trunk. Apart from this‚ they have two big ears and a short tail. Elephants are vegetarian. They eat all kinds of plants especially bananas. They

Plant and animal cells have several differences and similarities. For example‚ animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes.
