When gardening, there are lots of tasks required to achieve the beautiful desired outcome. Research shows how water distribution is essential to plant growth. Both garden beds at the Chattanooga Girls Leadership Academy need water, but different amounts. In our area, because of climate change, Chattanooga has a rainfall that alternates between flooding, normal, and drought situations. One way to address this issue of the climate-change conditions, is to use a raised bed, which would be conducive…

Photosynthesis and Leaf Structure Experiment Introduction The primary function of leaves is to conduct photosynthesis, a biochemical process in which plants, as well as a variety of bacteria and protists produce food from sunlight (EEB, 2016). Photosynthesis requires the acquisition light, water, and carbon dioxide and the removal of oxygen. Sodium bicarbonate is added as the bicarbonate ion acts as a carbon source for photosynthesis. Light independent reactions are catalyzed through the power…

A niche is the role or part that an organism plays in it’s specific ecosystem or habitat. An example would be a sunflower. The sunflower inhabits a grassy area and the role that it plays in the area is that it is the producer that gives off energy to the other trophic levels that also inhabit the grassy area. (1) In total, I found 7 different kinds of bacteria in the columns. (2) -In the Controlled Column, I found Cyanobacteria (5) along the top of the column. This bacteria causes the lighter…

Introduction Plants use both sodium and chloride to aid in normal function. Sodium is not essential in most plants, it can be used in small amounts as a micronutrient; partially replace potassium in some plants, aid in operation of stomata, and increase the plants ability to absorb water. In large amounts, typically above fifty parts per million, sodium toxicity occurs, resulting in necrosis which may kill the plant; sodium deficiency poses no threat to the plant as it is not an essential…

1) Describe Figure 1. (10 points) Figure 1 describes the photosynthetic light response between Beech and Oak plantations grown in patch harvest and shelterwood habitats, more clearly the comparison of photosynthetic rates v.s. light intensity response. As shown, Oak in patch harvest and Beech in shelterwood are having more photosynthetic efficiency in contrast to the remaining two, Beech in patch harvest, and Oak in shelterwood, having low effiency. Further proven by the slopes of the curves,…

Abstract The investigation was conducted see the effects of salinity on pant life more closely, with series of plants watered with different percentages of salt water. To determine how different salinity levels effect the plants growth, and also observe the other effects, if any, that may occur to the plant. The experiment was set up and each plant was watered with different levels of salinity, and measurements of the height and number of leaves was taken twice a week. The results concluded that…

Abstract: For this lab my group and I wanted to measure the rate of photosynthesis. We did this lab twice, both with slightly different environments so that we could see what changing the factors did to the rate. We found the rate of photosynthesis by taking hole punched pieces of a leaf and placing them inside of a syringe with sodium bicarbonate buffer. We then pulled the plunger part of the syringe back which lets the bicarbonate solution infiltrate the air spaces in the piece of leaf. After…

I chose Wicked Plants by Amy Stewart over the others on the list of approved books because it sounded more interesting and more relevant than some that just focused on one branch of Botany, instead of the entire wicked spectrum like Stewart does. I like how she breaks up the world of devious plants into seven distinct categories. The plants are reported on alphabetically with relation to their crime, but with a heading that falls under one of the seven wicked categories; deadly, destructive,…

4. Write out the balanced chemical equation for photosynthesis (no peeking!). Sunlight energy + 6H201 + 6C1O2 —> 6O2 + C6H12O6 5. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant? The factors that affect the rate of photosynthesis are the amount of light, the color of the light, and the amount of carbon dioxide. 6. Compare and contrast the information gained from the experiment about the factors that affect the rate of photosynthesis with…

The grand majority of plants use photosynthesis to obtain their energy to sustain. Plants perform photosynthesis by converting natural light into chemical energy *.In photosynthesis there are three different types of metabolic pathways for carbon fixation, this includes C3, C4 and CAM*. the CAM method was not observed in this lab. In the C3 method the plant converts CO2 to 3- phosphogylycerate which a 3 carbon which then enters the calvin cycle of photosynthesis *. While in the C4 methode CO2 is…
