IB Internal Assessment BIOLOGY STANDARD LEVEL PHOTOSYNTHESIS PRACTICAL REPORT Candidate Name: Meara Berhan Ahmed Candidate number: 000790 – 0003 (Word count: 4500) Examination session: November 2015 Design Research Question What is the effect of altering the distance ( ±0.05 cm) of the Elodea Canadensis aquatic plant from a light source at (5cm, 15cm, 25cm, 35cm and 45cm) on the photosynthetic rate by counting the number of oxygen bubbles rising up the test tube per minute (min^(-1))? Aim: To investigate the how the photosynthetic rate of Elodea Canadensis is affected by varying its distance (cm) ( ±0.05) from the light source at (5cm, 15cm, 25cm, 35cm and 45cm) by counting the number of oxygen bubbles rising up the test tube per minute (min^(-1)). Background Information: Photosynthesis is the process by which plants use energy from sunlight to produce chemical energy in the form of glucose, which cellular respiration then converts into ATP (Farabee, 2010). The chemical equation for photosynthesis is: 6ã€â€"COã€â€"_2+ H_2 O→C_6 H_12 O_6+ ã€â€"6Oã€â€"_2 There are two stages to photosynthesis. The first stage of photosynthesis is a set of reactions typically referred to as the light-independent reactions (Damon, 2007). The light-independent reactions predominantly involve photosynthetic pigments (including chlorophyll) absorbing light energy and undergoing a conversion into chemical energy known as Adenosine Triphosphate (ATP). Also, light energy is utilised by the plant to undergoShow MoreRelatedIB Bio lab report on photosynthesis1509 Words   |  7 PagesThe effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis, there are two main parts, including light dependent and light-independent reactions. Plants use the energy from light for producing sugar, which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucoseRead MorePhotosynthesis Lab Report866 Words   |  4 Pages Photosynthesis Lab 8 Section 022 Kaileen Savage Tanushree Majumber Introduction â€Å"Photosynthesis is a biochemical process for building carbohydrates using energy from sunlight and carbon dioxide taken from the air†, (Morris, J.

The plant’s chloroplasts, along with water, carbon dioxide, and light are the essential elements required for photosynthesis to take place. The â€Å"photo† part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light---- (CH2O)N + O2 As shown in the equation, photosynthesis produces carbohydratesRead MoreGesabelle1845 Words   |  8 Pages | Zachary SpoonerGrade/Class/Subject: Grade 8, Team A, Science | | Unit/Theme: Introduction to Basic Concepts of Ecology Standards: Region: USA- NAS- Science Education Standards National Academy of Science Type of Standard: Science Content Standards Grade Range: Grades 5-8 Content Standard: Life Science Area- POPULATIONS AND ECOSYSTEMS: A population consists of all individuals of a species that occur together at a given place and time.

One may now declare that a writer has no knowledge of microbiology, or any biology for that matter, and is in no way shape or form qualified to write a book about said topics.

As a matter of fact, there are states in which water can be available depending on temperature, and they are ice as solid water, steam as water in gaseous state and liquid water at standard temperature and pressure (Mobley, 1994). These three states are well known to co-exist on earth, having other inconsequential forms like cloud, fog and dew. Most importantly, water is known to cover 71% of the total earth’s surface, a worthy reason
