pollution emitted by human activities‚ such as factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water has a pH of 5.6‚ acid rain has a pH of 5 or less‚ which is acidic enough to harm plant life. Due to the reactivity of acid rain‚ the cell processes of plants are disrupted‚ and the cells die or become unable to function properly

The Wonders of Plants Experiment 2 – Upside Down Mungbeans Experiment 3 – Plant Labyrinth 6/18/2015 Mt Gravatt State High School Trinity Wong Abstract Introduction: Plants can’t move like animals do but they respond to certain stimuli‚ making them change the direction in which they grow. Plants are very sensitive to their environment and have evolved many forms of "tropisms" in order to ensure their survival. A tropism is a growth movement whose direction is determined by the direction

Lab 4: Plant Transpiration Project By Shelby Hyde Lab 030 Date Due: March 12‚ 2013 The Effect of Wind on the Rate of Transpiration Introduction: Transpiration is the process through which water is evaporated from plants. This serves many purposes‚ including thermoregulation and the diffusion of CO2‚ but most importantly creates a water potential difference which causes the mass flow of water and nutrients from the roots to the leaves of the plant. Transpiration is accomplished through structures

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica

The Genetics of Fast Plants Kristin Phillips Dr. Orlando April 4‚ 2014 Abstract The experiment that was being completed was the genetics of plants using Fast Plants. The purpose of this project was to understand Mendel’s concept of a Dihybrid by performing similar crosses and calculated the phenotypes that are displayed. This project was conducted over many weeks by planting F1 seed and waiting for them to grow then cross-pollinating the F1 plants to produce the F2 seeds. Next students

Almost all plants have roots that grow into the soil to help support its life. Roots are used by the plants to take nutrients and water out of the soil and send it through the plant. They also stabilize the plant. The root is made up multiple parts starting at the bottom with the root cap‚ then the zone of cell division next is the zone of cell elongation‚ and at the top of the root is the zone of differentiation. To figure out what section of the root has the highest number of cells in mitosis we

2011 Plants and Nitrogen Lab Report Introduction: Plants need ammonia‚ a combination of nitrogen and hydrogen‚ or nitrate‚ a form of inorganic nitrogen to grow. Most nitrogen is found in the atmosphere. However‚ plants and animals cannot directly absorb the nitrogen found in the atmosphere. Instead nitrogen gas is captured from the air by species of bacteria that lie in the water‚ soil‚ or grow on the roots of some plants. These bacteria convert the nitrogen into a form usable by plants. The

A ’tropism’ is a growth in response to a stimulus. Plants grow towards sources of water and light‚ which they need to survive and grow. Auxin is a plant hormone produced in the stem tips and roots‚ which controls the direction of growth. Plant hormones are used in weedkillers‚ rooting powder and to control fruit ripening. Tropisms The direction of plant growth Plants need light and water for photosynthesis. They have developed responses called tropisms to help make sure they grow towards sources

Introduction: Plant hormones and growth regulators are chemicals that affect flowering‚ aging‚ root growth‚ killing of leaves‚ promotion of stem elongation‚ color enhancement of fruit‚ prevention of leafing‚ and many other conditions. Very small concentrations of these substances produce major growth changes. All plants produce hormones naturally‚ and growth regulators can be applied by people to are applied to plants by people. Plant growth regulators may be synthetic compounds that mimic naturally
