Chloroplast

Photosynthesis is the process where energy from the sun gets converted into glucose for the plant to use as food. The energy from the sun gets trapped in the chloroplasts and together with carbon dioxide and water, it is turned into glucose and oxygen. The glucose eventually gets used as energy for the plant to live and the oxygen is a waste product that is released. The oxygen is used by humans during cellular respiration. Photosynthesis began over 2 billion years ago when an organism first…

Basic Biology The documents I attached include a lab report, worksheets, notes and one exam. My most memorable experiences in biology were in the lab. I got to test the effectiveness of lactase drops when exposed to solutions containing different pH or temperatures. My results indicated that the lactase enzyme had the optimal catalytic activity at temperatures similar to those found in the human stomach; however, the low pH in the stomach–ranging from 2 to 5– rendered the drops ineffective…

every living cell has water in it. Every living cell in surrounded by fluids. Water dissolves more substances then any other liquid. The ions dissolved in water are needed by organisms for growth and to manufacture various body substances. Every organism must keep it internal body fluids in balance in order to survive. Water uptake must balance water loss. Water- roots and root hair absorb water from the soil by osmosis. Roots are long and have a large surface area. Roots have thousand of root…

1. Introduction background information. What is the purpose of this experiment? What happens during photosynthesis? What is the role of a photosynthetic pigment? Also, state your hypothesis, independent and dependent variable(s) in this experiment. Photosynthesis is the development of the process which all living plants get their food from the sun, plants absorbed them water from the roots, plants get their food from the sunlight, plants get help of water and carbon dioxide to survive and give…

Prokaryotic organisms have existed for billions of years. These prokaryotic cells have gone through enough environmental changes to learn how to adapt quickly. As small organisms that reproduce rapidly, bacteria cells are the most abundant organisms on earth and the most important. Gram staining is used by scientists to help identify and classify bacteria due to the fact that it is difficult to discern unstained bacteria through light microscopes (1). Since bacteria are small organisms that are…

Found in the chloroplasts of plants, chlorophyll absorbs certain wavelengths of light within the visible light spectrum (webexhibits, 2016). Chlorophyll is able to absorb light colours such as red and blue however green is reflected making the plant appear green. Apart…

There is a big difference between what is theoretically known to be inside cells, and what can actually be seen under a light microscope. In fact, a light microscope can only capture larger cell components like the nucleus, chloroplasts, nucleoli, and vacuoles (Biology Department, 2015). This means that differentiating between organism classes would come down to the size, shape and potentially visible organelles of the…

Light Color and Photosynthesis Rate Introduction: How do the wavelength of visible light affect photosynthesis? Photosynthesis, a process used by plants and other organisms to convert light energy into chemical energy that can be released later to fuel the organisms’ activities, depends upon the absorption of light by pigments found in the plant leaves. Pigments, such as chlorophyll and carotenoids, absorb and reflect light based on the wavelength of light. To be more explicit, photosynthesis…

Purpose: To observe different species of living protists in pond water under the microscope. Taking note of their size, movements, and characteristics to classify the different types of protists from applying previous knowledge of protists. Materials: The materials in this lab that will be needed are a microscope, slide, coverslips, a pipette, and a dish of pond water. Procedure: Prepare a slide by using the pipette to apply two drops of pond water on a slide and properly place a…

[ Classification ] Sept. 26th Introduction: Classification systems provide a logical way to organize and name living organism, based on the fact that some organisms resemble one another while others do not. There are currently two classification systems of organisms, into 5 kingdoms or 3 domains, both are distinguished by specific characteristics. Kingdom Monera have no well defined internals as they lack membrane to bound organelles, and Protists are single celled organisms that may be plant…
