Abstract: The focus of this experiment was to identify unknown bacteria provided. The identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities‚ presence of particular enzymes‚ and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized
