Precipitation— • Our moisture supply • Measured with rain gauge o ACTET actual evapotranspiration • Evaporation—movement of water molecules from a wet surface into the air • Transpiration—cooling mechanism in plants (sweating for plants—cools them off) • Evapotranspiration-evaporation combined with transpiration—refers to the actual expenditure of water from land and plants o POTET potential evapotranspiration • The amount of water that would evaporate and transpire under optimum moisture

its stomata to allow diffusion of the gas into its leaves. However when a plant does this it also results in loss of water‚ as water vapour diffusing out of the leaves. Lost water however is drawn up through the xylem through a process called transpiration. Water is able to move in opposition to gravity due to the negative pressure of the vessels‚ and the cohesion-tension property of water‚ which allows water molecules to “stick together” and influence the movement of another water molecule. If it

Most organisms are active within a limited temperature range: * Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity in substrates: * Role of enzymes in metabolism: * Metabolism refers to all the chemical reactions occurring in organisms * Enzymes are biological catalysts which increase the rate of chemical reactions * Without enzymes‚ metabolism

1.) Roots support photosynthesis and respiration by absorbing minerals and water and by storing organic nutrients. They 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

Biology Notes - Ecology and Eco-Systems Environment It is everything that surrounds you. It includes all natural living and non-living things that are included within the environment. All living organisms depend on the natural environment they live in. A natural environment is very different to a man made environment because a man made environment is heavily influenced by people whereas a natural environment is effected by people by a very small amount.

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative
