Ecology Lab Report 4/17/12 Abstract Sampling Stomatal Densities of Various Species of Plants The importance of stomata is the fact that they control the intake of carbon dioxide and the loss of water in plants. The ratio of intake to loss creates a better picture of which plants adapt would to their environment and which would not. Eight different plant species were sampled the stomatal densities and compared them to their environments. The densities were recorded for each species

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.

Weaknesses: The experiment did not expand on the various types of plants used as well as the differences that would occur when using mesophytes compared to xerophytes or hydrophytes.

Planet Earth contains three compositional layers- CORE‚ MENTLE & CRUST. Core: At the centre is the densest of the three layers‚ the core. The core is a spherical mass‚ composed largely on metallic iron‚ with lesser amount of nickel and other elements. Mantle: The thick shell of dense‚ rocky matter that surrounds the core is mantle. The mantle is less dense than the core but denser than the outer most layer‚ the crust. Crust: Above the mantle lies the thinnest and outermost layer‚ the crust
