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

INTRODUCTION Plant pigments consist of four main chemicals. These are Chlorophylls‚ The carotenoids‚ Anthocyanin and Betacaine. The aims of this experiment is to separate the plant pigment into different colours using solvents and column chromatography. The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most

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

Abstract The hypothesis states that plants respire at a faster rate if they are exposed to wind‚ opposed to no wind. This was tested by putting one plant in water in front of a fan and the other plant in water‚ but with no fan. The results showed that the plant in front of the fan transpired more. However‚ since the plant blew cold air it affected the rate of transpiration and altered the experiment. Overall‚ this experiment supports the hypothesis that wind makes plants transpire more.
