Photosynthesis Reports Samples For Students

Section Number.

- Glycolysis refers to the process that takes place in the cytosol and through which a molecule of glucose is broken down into a compound called pyruvate ( Reece 167)
- Everthing is doubled since there is still more substrates required for respiration and therefore more energy is still produced as the substrate is not exhausted.( Reece 167)
- In the process of glycolysis 2 NADH, 2 ATP and 2 H+ are fomed. While in TCA 6NADH, 3 H+, 1 FADH2 and 2 ATP are formed. (Reece 176).

The Rate of Photosynthesis in Two Submerged Organisms (Cabomba and Ceratophyllum)

Introduction
In this experiment, the set alternative hypothesis was that the rate of oxygen production in Cabomba was significantly different from the rate of oxygen production in Ceratophyllum. This was informed by the report from a previous study by Van and colleagues (1976) that indicated that Cabomba had a lower rate of photosynthesis compared to Ceratophyllum and Hydrilla that had similar photosynthetic rate.

Materials and Methods

Experimental Design
The experimental independent variables were 6 grams for Ceratophyllum and Cabomba organisms while oxygen produced was the dependent variable. Water collected from the pond was used as the control in the experiment. The question ...

Part 1: Answers to Preliminary Questions

• Photosynthesis is the process by which green plants use sunlight energy to manufacture food using water and carbon dioxide as raw materials.

• An increase in the intensity of sunlight increases the rate of photosynthesis up to a given level.

• Photosynthesis and respiration processes complement each other. It is possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions. This can be conducted by setting up an experiment with two sets of experimental set-ups. In each set-up, there should be two test-tubes: one with a high concentration of carbon dioxide and another with a high concentration of oxygen. One pair of test tubes, consisting of a test-tube with a high concentration of oxygen, ...

Abstract

Water is an important chemical owing to its various uses by living things. Most chemical reactions within the bodied of living things require water in order to occur. It is purported that life evolved from water some 3.8 billion year ago following the organization of inorganic and organic molecule to form as prokaryotic cells. Besides, the well being of a cell is overly dependent of the balance between the water and the dissolved substances in the water. In this regards, the cell can permit water molecules to move in and out of the cell; the process in called Osmosis.

Introduction

The null hypothesis for the experiment was that oxygen production is the same in both plants while the alternative hypothesis was that oxygen production and thus the rate of photosynthesis is higher in Ceratophyllum than in Cabomba due to its efficiency in carbon dioxide utilization (Kitaya, Murakami, & Takeuchi, 2003).

Materials and Methods

Experimental Design
The research question to be answered in the experiment was whether there is rate difference, in oxygen production, in oxygen production between Ceratophyllum and Cabomba. It was predicted that each of the plants would have different oxygen production rates. The dependent variable was the rate in oxygen ...

How is Plant Growth Affected by Sunlight?

Introduction
Background information
Sunlight is essential to plants. Plants in dark room tend to grow towards sunlight. When they lack sunlight, photosynthesis does not take place causing them to wither and die.
Photosynthesis takes place in the leaves of a plant. In plant leaves, there are organelles called chloroplast. They form site for photosynthesis process. They are very many in a leaf.

Within chloroplast, there is chlorophyll, that are usually green in color, hence the green coloration in plants.

Plants require air, water and sunlight for photosynthesis to occur. Air goes inside the leaf via stomata, water is absorbed from the ground through the roots and sunlight is absorbed by the chloroplasts in the leaves.
Chemical ...

Abstract

The purpose of our experiment was to visualize the effect of light intensity on oxygen production. In the capacity of a test subject we used algal cultures. For these researches we used the Winkler method of titration. Our experiment results showed that there is an effect of light intensity on oxygen production. Our research has a great significance for agriculture, biochemistry and biophysics.

Introduction

Photosynthesis is the metabolic process by which plants trap solar energy, convert it to chemical energy, and store it in the bonds of organic nutrient molecules, such as glucose. Nearly all types of plants and algae, as well ...

BIO 103

Introduction:
Plant cells photosynthesize to produce glucose. By doing this, light energy, coming from the sun, is transformed in chemical energy, glucose. Oxygen is also produced from carbon dioxide and water. The process occurs by light dependent reactions (in thylakoids) and dark dependent reactions (in the stroma). In the light, plants produce energy molecules, such as ATP and NADPH; in the dark, they use those molecules to fix the CO2. The excess of glucose during photosynthesis can convert into starch.

Purpose:

The purpose of this experiment was to determine the differences between leaves from plants exposed to the sun and ...

Aim: The aim of this project is to determine the influence of sunlight and shade on the characteristic of leaf morphology.
Background: The gradient in light received by the leaves, compel them to adapt for optimum growth in a particular environment. This adaptation takes place gradually, with changes in certain morphological features. These morphological changes that take place with time and space in which the plant grows is defined as succession and has a role to play in evolution. Certain environmental factors like shade and sunlight can present as a slightly adverse condition that affect plant growth. In order ...

Phosphorus and Nitrogen Limitation on Plants Growth

Introduction
Plant growth and development rely on multiple environmental factors that include light intensity, temperature, water availability and vital minerals and nutrients. During the insufficiency of exogenous resources, plants maintain this imbalance through allocating the new biomass to that organ which specifically needs that insufficient nutrient (Hermans et al., 2006). Nutrients like nitrogen (N) and phosphorus (P) play significant roles in a plant life. They influence various metabolic factors of plant life through cooperating with each other such as in biomass distribution as well as regulating chlorophyll A and B levels.
The objective of this experiment is to understand ...

Introduction

Elodea canadensis is a perennial hydrophyte, which is native to the majority of North America and was first recorded in about 1836 from the British Isles (Hackney, 1992). Young plants at first begin with a seedling stem and roots grow in mud at the underneath of water. More adventitious roots arise at intervals along the stem. The leaves are translucent, bright green, oblong, 1-4 mm broad and 6-17 mm long, borne in whorls of three round the stem (Rose, 2006). It lives completely submerged.

Blepharisma is a unicellular ciliate protists genus found in salt and fresh water (Miyake, Harumoto, Salvi, & Rivola, ...

Introduction

Transpiration is the process involving the movement of water from the roots through the xylem to the atmosphere via the stomata. About 95% of the water absorbed by plants is transpired to the atmosphere. The plant uses the remaining 5% for its metabolic functions such as photosynthesis and respiration (Ahmadi and Baker, 259).
The movement of water in the vascular plant is as a result of the coordination among the three plant organs: the root, the stem, and the leaf. Roots have root hairs located toward its growing tip. The root hairs form extensions of the epidermal cells referred ...

VEGETATION ANALYSIS LAB REPORT

INTRODUCTION
Growth in plant may be referred to as a progressive development in plant and can be expressed in terms of dry weight, length, diameter, and height. The growth of the plant results in the development of different structures, which all the conditions are optimum results in a proportionally matured plant. Agents that affect plant growth may be classified as environmental or genetic. Environmental factors affecting plant growth include the content of the moisture in the soil, temperature, radiations from the sun, soil reaction, mineral nutrients that are available, biotic factors and atmospheric composition among others. Each of these factors ...
