  • Sea Slug's Solar Energy Theory

    Article 1: Scientists unravel the colorful sea slug's solar-energy theory 1) Why are chloroplasts important for plants? Chloroplasts are important for plants because they contain Chlorophyll, used in photosynthesis. The Chlorophyll is what made it possible for plants to absorb and process the sun's energy and combine it with carbon dioxide and water to grow and make food. Photosynthesis also releases oxygen for humans to breath. 2) List two reasons and explain why the chloroplasts were helpful for the sea slug. One reason for why the chloroplasts are helpful for the sea slugs is because they store up the chloroplasts in order to become solar-powered animal-plant combinations. Also, chloroplasts is important as a long-term energy source they…

  • How Light Affects Photosynthesis

    The Effect of Different Colored Lights on Photosynthesis My group studied the effect of light on photosynthesis in our experiment. Photosynthesis occurs in the chloroplast of the cell. Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells that have chlorophyll. In our experiment we tested how different colored lights would…

  • Importance And Importance Of Photosynthesis In Agriculture

    into chemical energy or food. leaves have a flat base which allows them to absorb more light. they have a very thin layer which allows carbon dioxide in and oxygen to diffuse out easily. chlorophyl plays a large role in photosynthesis this gives the leave its green colour and transfers light energy into chemical energy or food. The veins that can be seen along the leaf transport substances to and from the cells of the leaf. there are several differant layers of a leaf. The waterproof cuticle…

  • Chloroplast Theory

    The Endosybiant theory states that the mitochondria and the chloroplasts were at one point in evolution, prokaryotic cells. It is said that before they had the function and job that they have today, that the mitochondria and the chloroplasts lived on their own and commonly took shelter inside of larger host cells. There they provided the host cell with the nutrients that it needed to live, and in return the host cell gave the cells a protected place to live. Eventually the host cell, the…

  • Photosynthesis Lab Report

    Photosynthesis is the process by which plants and other organisms create energy. Light energy is converted into chemical energy that can be stored and used. CO2, water and light are converted into glucose and oxygen. The general chemical formula for this is, CO2 + H2O + light energy → Glucose + O2. In this experiment, we will test the relationship between the rate of photosynthesis and the water consumed by the plant; we will be testing tap water–for a control, sugar water and salt water. If we…

  • Compare And Contrast Plant Pigment By Shirley Raps And Jeffrey Harborne

    centers that require the lowest amount of energy to donate those excited electrons. These two chlorophylls also have the longest wavelengths of maximum light absorption (Raps and Harborne). The authors then go on to describe the nonphotosynthetic pigments. According to Raps and Harborne, anthocyanins are “water-soluble plant pigments found in petals, flowers, and the lower epidermis of leaves. They are produced in the cytoplasm and usually transported into the cell vacuole.” These pigments are…

  • Light Filtration And Photosynthesis Essay

    control group is the group that did not place paper under the beaker containing the leaves. The constant variables are the 6% sodium bicarbonate solution, the lighting in the room, temperature and the amount and size of the leaf discs. An extraneous variable is the temperature around the room, the age of the leaves used and the amount of light. The temperature of the room was to stay constant, however, with the heat generated from the people in the room, the heat from one’s hands while holding…

  • Importance Of Chloroplasts

    What are chloroplasts, where did they come from and what are they good for? We all know that chloroplasts are the site for photosynthesis in plants and what makes plants autotrophic. It allows the plant to be known as the ‘producer’ in a food chain. Being such an essential part of the plant cell, the question arises, where exactly did it come from in the first place: has it been a part of the plant cell since the beginning of time or did it evolve from some other species, and how is it able to…

  • Alfalfa's Relationship With Oats

    the colonization of terrestrial ecosystems. Ever since late Silurian (425 Ma), land plants have been competing, evolving and diverging to give rise to new species, while nearly all plant species that existed up until 10kya have gone extinct and there is an estimated 400,000 plant species in present day (Chapman 2009). All plants require water, sunlight, nutrients, and territory for their survival. Water and sunlight are required for photosynthesis, the process of creating energy for organismal…

  • Essay On Respiration And Photosynthesis

    "past" combine with oxygen to form water. That's why we need oxygen; in the absence of oxygen, this process can not take place (Williams, 1999). Many years ago, the development of photosynthesis occurred in bacteria. While the molecular oxygen (O2) obtained in the air, organisms could use O2 for respiration started evolving, breath "aerobic" come to be a predominant method of metabolism between bacteria and certain ancient. Eukaryotic cells were grown somewhere between one and two billion years…
