The environment can be defined as the surroundings in which as organism lives, including the climate, the physical and chemical conditions of its habitat and its relationship with other living things.
Given the above understanding, it is therefore important that the right environment factors are in existence for some chemical reactions to take place. In the absence of optimum environmental factors, organisms would be compelled to adapt themselves to the prevailing environment. Cellular respiration and photosynthesis are two important chemical reactions for which the environment is of paramount importance.
Photosynthesis is the process by which green plants synthesize organic compounds, primarily sugars, from carbon dioxide, and water using sunlight and chlorophyll.
6 CO2 + 6 H2O C6H12O6 + 6 O2
Respiration is the process by which plants and animals metabolically break down organic compounds, mainly carbohydrates to release energy for use such as in the bodily processes, such as active transport. It can be either aerobic or anaerobic.
Aerobic meaning respiration requires the presence of oxygen so as to take place. Oxygen is taken by the cell and CO2 out through diffusion or active transport. The carbon dioxide and water produced are used by plants during photosynthesis.
C6H12O6 + 6 CO2 6 H2O + 6 CO 2 + ENERGY
In anaerobic respiration sugar is broken down to produce ethanol in plants and lactic acid in animals.
C6H12O6 2 CH3CH2OH + 2CO2 +ENERGY
C6H12O6 2CH3CH(OH)COOH + ENERGY

- Anisa Linton Biology 121 April 15, 2016 Professor McManus The effect of different environments on rates of respiration or photosynthesis in spinach (Spinacia oleracea) and white pine (Pinus strobus) Introduction Photosynthesis is an essential process for life on earth. This is the process in which photoautotrophs such as plants, algae, unicellular eukaryotes, and some prokaryotes, take carbon dioxide (CO₂) from the atmosphere and visible light from the sun’s rays and convert it into chemical energy that is collected in the form of sugar and organic molecules (Reece et al....

- 1. Introduction Photosynthesis occurs in plants and some organisms from the Kingdom Protista, such as algae. It is the process of converting light energy into chemical energy and storing it in the bonds of sugar of the organism. This process takes place in the leaves of a plant specifically in the chloroplast and it uses chlorophyll. In order to make sugar plants require only the following: Light energy, Water, and Carbon Dioxide. Chlorophyll is made into the membranes of the thylakoids. (Clermont Staff, 2000) Thylakoid is a membranous body fluid of the chloroplast, which contains the photosynthetic pigments and reaction centres.... [tags: Photosynthesis, Oxygen, Carbon dioxide]

- I was running late to my class. As I entered my Biology class, I noticed that there were no chairs available. I frantically looked around to where I could sit for the class period. I finally decided that I would go to the back of the class as the teacher stood there lecturing the class about Cellular Respiration and Photosynthesis. As I sat in the back, I wondered how was I supposed to focus and learn in this type of environment. There were too many people. Some people chatted, some people texted on their phones, and some people slept.... [tags: Education, School, Teacher, Learning]

- Investigate the Effect of Moisture Content on Wheat Grain Seed's Respiration Rate HYPOTHESIS: There will be a positive correlation between moisture content of wheat grains and their respiration rate. Therefore as the moisture content (independent variable) increases so will the respiration rate (dependent variable). The rationale behind the hypothesis came from studying photosynthesis in plants. During the light-dependent reactions of photosynthesis, the photolysis of water (H2O) occurs inside photosystem II.... [tags: GCSE Biology A2 A-Level Coursework]

An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea
- An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea Plan: Method: 1) First I will put some water into a boiling tube and add 5 spatulas of Sodium Hydrogen Carbonate. I will add 5 spatulas of Sodium Hydrogen Carbonate as it reacts with water and forms carbon dioxide; also I have so much so that I have carbon dioxide in excess. 2) Then I will cut off 5cm of elodea and place it into the boiling tube. 3) Thirdly I will place the boiling tube in a test tube holder 5cm in front of the light source....

- Carbon Dioxide: Good or Bad for Rainforests. Amongst scientists, there is an ongoing debate whether cCarbon dioxide (CO2) has a positive or negative impact on ecosystems around the world. This article is focussing on the impact of CO2 on the flora of rainforest ecosystem. The causes of CO2 imbalance in rainforests are correlated with the carbon cycle. The carbon cycle is the exchange of CO2 between living things, decomposition of organisms, deforestation and combustion of fossil fuels. The aim of this article is discuss why high levels of CO2 are bad for rainforest ecosystems.... [tags: Carbon dioxide, Photosynthesis, Oxygen]

- Tropical rainforest covers only a relatively small proportion of our planet, and yet it is considered to be one of the most significant ecosystems, and its loss through deforestation and burning is considered to be of global importance. Explain why. Introduction Tropical rainforests are highly important to the global ecosystem and human existence in the world. Occupying only 6% of the earth’s land areas, tropical rainforests sustain 10-50 million species, which is over half of the world’s biodiversity, far higher than biodiversity in sub-tropical, temperate, and boreal ecosystems (IUCN, 2006)....

- 1. Explain why the following statement is incorrect. Plants perform photosynthesis, but only animals perform cellular respiration. It is true that plants perform photosynthesis. What it is not true, it is that only animals perform cellular respiration. Cellular respiration is the process in which an organism obtains its energy. All living organisms perform cellular respiration, whether they are plants or animals. For instance, every cell in an animal requires oxygen to perform cellular respiration which gives off carbon dioxide and water as waste products.... [tags: Metabolism, Cellular respiration, Glucose]

- Water quality is measured by several factors, such as the concentration of dissolved oxygen, the pH level in the water, the salinity of the water or salt content in the water, the temperature of the water and its turbidity or the ability to see through the waters surface, there are also other contaminants that may affect water quality. Dissolved oxygen (D.O) is an important variable in the water quality of fresh water ponds as it is vital for aquatic life such as fish to survive in the environment....

- Cellular respiration is the ability of a cell in an organism to metabolize chemicals in the production of adenosine triphosphate (ATP), the main energy molecule of the cell. There are two forms of cellular respiration. Chemotrophic respiration, which is used by animals and phototrophic respiration (a.k.a. photosynthesis) used by plants and fungi. Chemotrophic respiration requires oxygen to efficiently make ATP and gives off carbon dioxide as a waste product. Photosynthesis requires carbon dioxide and gives off oxygen as a waste product....
