protects it from damage. Branches grow from the trunk. They spread out so that the leaves can get more sunlight. The leaves of a tree are green most of the time‚ but they can come in many colours‚ shapes and sizes. The leaves take in sunlight and use water and food from the roots to make the tree grow‚ and to reproduce. Trees and shrubs take in water and carbon dioxide and give out oxygen with sunlight to form sugars. This is the opposite of what animals do in respiration. Plants also do some respiration

laugh starts getting better it makes new species and in the end it brings her to new fathoms and joy to all. Susan uses many metaphors throughout her poem and it creates many different scenes in your mind. Susan also uses many symbols such as the sunlight‚ the prayer wheel and the diver’s bell. In the first three verses of the poem Susan states that the laugh resembles unsynchronized clocks. Susan was using a metaphor to explain that the laugh is similar to clocks in a watchmaker’s shop when all

Eelgrass This document will discuss the aquatic plant eelgrass. It will describe its role in the ecosystem including its usefulness to humans. It will also describe how human impact is causing it to suffer‚ and will conclude with various ways of solving these problems. Eelgrass (zostera) is a very important plant in the Pacific ocean. It helps sustain many life forms and protects growing organisms through the change of tides (Tyler-Walters‚ H. 2007) These thin blades of grass are vital to have

Investigation of the rate of photosynthesis of pondweed. Research question: How does the concentration of sodium bicarbonate relate to the amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%

Solar Energy People have been using solar energy by different ways for centuries. As early as the 7th century B.C.‚ people were using glasses to concentrate the sunlight into the beams so hot. This beams were causing wood to catch fire. [pic] Figure 1. Concentrating the Sunlight Note. Renewable Energy Fair.(n.d.). history1.

Death is something that is inevitable‚ It’s not something humans and life in general can’t run away from. It is especially something soldiers cannot walk away from. In “The Things They Carried”‚ Tim O’Brien’s characters suffer this reality time and time again in the Vietnam War. A war that costed the life of thousands of American servicemen. Men who suffered horrific conditions and watched their close friends die in devastating combat and treacherous terrain. It could be easy to call the men who

Class: Environmental systems and societies Teacher: David. A Student name: Krutarth Mehta Date: 13/3 Relevant to: 2.5.2. Describe photosynthesis in terms of inputs‚ outputs and energy transformations. Criteria to be assessed: PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants

INTRODUCTION The purpose of this mathematical report is to investigate a tree’s ability to capture sunlight in relation to possible correlations between the tree’s growing capacity and leaf length. A variety of mathematic techniques will be used to examine how a tree’s height relates to the length of its leaves. This data will then be used to analyse the tree’s ability to efficiently capture sunlight and move liquid around the tree. It is predicted that this report will prove that as a tree’s growing

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the
