Subject Title : Biology Program : Diploma Program (IB) School Year : 2014-2016 Instructor : Jeffrey Joseph Y. Araula‚ MMM NATURE OF THE SUBJECT Biology is the study of life. The first organisms appeared on the planet over 3 billion years ago and‚ through reproduction and natural selection‚ have given rise to the 8 million or so different species alive today. Estimates vary‚ but over the course of evolution 4 billion species could have been produced. Most of these flourished for a

differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons at the end of the chain

Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

The light independent reaction uses the chemical energy to make organic molecules Overview of Photosynthesis 8.2.3 Explain the light dependent reactions The light dependent reactions occur on the thylakoid membrane and may occur by either cyclic or non-cyclic processes In both processes‚ light excites chlorophyll (clustered in photosystems) which release electrons that pass through an electron transport chain‚ making ATP (photophosphorylation) Non-Cyclic

on the historical development of the cell membrane structure‚ in which i described how the discovery of the hydrophobic properties of lipids eventually gave rise to the fluid mosaic model. In doing so‚ I learned how to structure a scientific report‚ gather information from reliable sources‚ and cite references appropriately. With these skills‚ I am prepared for more independent study as I move into higher education. I love the practical element of biology which is supported by the practical techniques
