-How plants get liquid and minerals- Flowers absorb liquid through their roots‚ which are attached to xylem vessels. Xylem vessels are tubes that can expand through several feet of tissue and be .7mm in diameter. Their walls are thickened with cellulose deposits. Xylem bring water up to the leaves and petals of the plant. Even without contact with the roots‚ the xylem can still absorb water. Because of this‚ a cut flower usually doesn’t die for a couple days (as long as it is placed in water of

What I would like to get out of taking this class is a better understanding of what the world is made of and how people live in there part of the globe. I am from Bedford‚ New York. Bedford is about an hour north of New York City. 2. Weather and Climate: Bedford New York is located in North Eastern United States. The average temperature there is around

Three major causes of soil erosion There are three causes of soil erosion over cultivation‚ overgrazing‚ and deforestation. All of these causes can be corrected in different ways. Over cultivation is when the land is repeatedly tiling and producing crops faster than the soil can restore resulting in a decrease in the soil value and productivity. One of the ways that over cultivation can be corrected is by a technique called no-till agriculture. No-till agriculture is a procedure where chemicals

Recycling can turn the wasted resources that end up on street corners into a valuable commodity to boost agricultural production and fertility of soil. It helps in providing new jobs‚ developing new skills and contributing to community projects and social cohesion. Recycling can also reduce the amount of waste going to landfill and incineration. There are numerous reasons of recycling‚ including

SOIL LAB: The Wealth Beneath Your Feet Purpose: To determine potential growth based on tests of physical characteristics such as pH‚ fertility and consistency. Pre-Lab: TO start off our investigation‚ we had to gather soil. Our group decided to get it from below a tree‚ right next to the trunk. In terms on fertility‚ we rated our soil to be a 4 (1 being the least fertile‚ 10 being the most). We rated it rather high because it was in a place where it had not been tampered with making it better

growth and germination of plants lie the nutrients they receive from the soil. The nutrients required for growth are classified into two groupings‚ macronutirents and micronutrients. Macronutrients are those that are needed in very large amounts‚ and whose absence can do a great harm to the development of the plant life. These nutrients include calcium‚ nitrogen‚ phosphorus‚ and potassium‚ and are very sparse in most soils‚ making them the primary ingredients in most fertilizers. The other‚ more

Specific Environments Abstract: The thing that I did was analyze soil to see if bacteria could live in that environment. The reason why I did it was because I wanted to find out where in the environment bacteria and fungi can live. In order to do my study I had to collect a sample of soil and put it in a dish. After I did that I could look at it underneath a microscope. I found that bacteria did in fact live in the soil so the soil was a sustainable environment for the bacteria to live. Introduction:

In the absence of any of the elements‚ plant can not complete their life cycle and these can not be supplemented by other elements. They are essential because they are important to plant functions. There are 17 essential plant nutrients. Carbon and oxygen are absorbed from the air‚ while other nutrients including water are obtained from the soil. Plants must obtain the mineral
