Communication‚ Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal

Abstract Stomata is important to plants because of their role in gas exchange and photosynthesis. Clear nail polish and clear plastic tape were used to make leaf impressions of A. floridanum. Once impressions were completed‚ compound microscopes were used to count the total number of stomata per slide. The counts of stomata were used to find stomatal densities‚ along with the open/closed ratios of stomata. Stomatal density and open/close ratio of stomata did not differ between the two locations

transpiration rate for the experiment was 2.904. The relationship between the control and the experiment was significant‚ meaning the null hypothesis was rejected. Introduction: Plants require CO2 to perform functions like photosynthesis. Stomata on the bottom of leaves open and close in order to allow CO2 to diffuse into the plant and O2 to exit them. Transpiration is essential for maintaining the plants water cycle but it is a byproduct of opening and closing the stomata. Transpiration starts in

REVISION NOTES FOR PRELIM BIOLOGY: [ A LOCAL ECOSYSTEM ] ~ Ecosystems: “any area that contains living organisms interacting with each other and their environment. In a balanced ecosystem‚ there is a flow of energy through it and recycling of some materials” Inputs and Outputs of Ecosystems include: - the energy flow through the ecosystem; energy from the sun flows one way through‚ with heat loss at each trophic level - the input and recycling of inorganic and organic material (matter) - the

and nitrogen cycles. These cycles are part of photosynthesis. These are a chain that keeps everything going in the word. These cycles keep animal alive and plants and people breathing. Carbon cycle is an Importation one of the cycle on earth. You get carbon atoms from co2 then become carbon atoms of the organic molecules are making up the plant bodies. Then the carbon atoms are eaten my animals. This cycle comes from fossil fuel also this create CO2. The carbon atoms cycle from atmosphere through

across a membrane to create ATP. Also called the “Proton Pump” Creates a electrochemical gradient. Autotroph: Organism which is capable to make its own energy. Production of own food from CO2 Synthesizes organic carbon molecules using inorganic carbon. (CO2) Example: Plant; Performs photosynthesis. Other Example: Sulphur bacteria: bacteria may use other organic compounds (oxidation reactions‚ etc.) Bacillus bacteria: Bacteria which is rod-shaped‚ gram-positive‚ aerobic and anaerobic.
