In the experiment‚ the effect of light intensity on the rate of photosynthesis will be tested. Photosynthesis is the process in which autotrophic plants create their own food (energy) from sunlight. Photosynthesis involves three ‘ingredients’ or reactants‚ carbon dioxide‚ water‚ and light energy (sunlight). Carbon dioxide and sunlight come in through a leaf’s stomata which are tiny holes‚ and water is absorbed through their roots. When all of these reactants are combined in a plant’s chloroplasts

This experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity‚ then more oxygen and glucose molecules will be produced‚ and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of

as pest in fish farming. This type of fish contributes to the severe erosion of river banks‚ a predator to some local fishes and a competitor of food for the local fishes. The fisher folks have been suffering from low catch due to the rapid growth of population of Janitor Fish. They consider these ugly-faced fishes as their enemy and they are calling-out for total eradication of these pests. As a solution‚ emulsifying fish is conducted. Fish emulsion comes primarily from the processing of a fish

Dried Papaya Leaves as Organic Mulch for Tomato Plants Abstract Mulching in agricultural provides a safe yet equally profitable method of enriching and fertilizing the soil planted with crops. Most often-used mulches are of organic composition‚ such as dry leaves and barks. Unlike synthetic fertilizers and herbicides‚ these organic mulches pose no or little damage to the soil and crops. In this study‚ the effectiveness of dried papaya leaves as organic mulch for tomato was tested. Papaya mulches

THE EFFECT OF LIGHT INTENSITY DURING PLANT GROWTH ON THE SIZE OF STOMATA IN DICOT LEAVES Christina Durgan Nicole Romero Vanessa Chilunda Biology 101‚ Thursday 1:15pm Claire Burkum 5 December‚ 2013 1. The hypothesis of this study is that the size of the stomata on the dicot leaves exposed to higher light intensity will be smaller compared to the size of the stomata on the dicot leaves exposed to lower light intensity. This is because at higher light intensity there is an increase in environmental

if I leave a plant in continuous light‚ then I expect that the plant will grow/ produce less than a plant in a normal amount of light from 6am to 9pm. This experiment was done‚ so that indoor growers know if they need to turn off their grow lights at night‚ or set them on an alarm‚ so that they can get full potential food production. There are many people without food‚ so this would help if one can produce more food. Only one of my trials supported my hypothesis‚ of the plant in normal light will

Plants and animals have a lot of things in common so much in fact i couldn’t fit half of them into this essay‚ there similarities and differences span from the smallest things like cells to huge thing like the whole organism. One thing that plants and animals both have in common is the fact that they adapt‚ the main thing isn’t that they adapt though it’s why they do it. Animals‚ plants‚ and humans all share the same thing they have a will to live in different ways maybe or some might want to live

WEAKNESSES OF INVESTIGATION 23 IMPROVEMENTS OR FUTURE INVESTIGATIONS 23 CONCLUSION 25 INTRODUCTION Hydroponics is a technique of growing plants without basing them in soil. Hydroponic systems have been used since ancient times; it is believed that the legendary Hanging Gardens of Babylon employed a technique of ‘flowing water’ to keep plants alive. Chinese and South American cultures appear to have used hydroponics in cultivating crops since around 1300AD (Turner. B. n.d.). There

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

the effect of changing light intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts of green plant cells. Photosynthesis
