so that it can be used by the organism. For example‚ when we looked at how plants get energy we say that plants’ main source of energy is sunlight. But‚ we noticed that light energy cannot be directly used by the plant. So‚ using the process of Photosynthesis plants can effectively turn light energy into “usable” or kinetic energy. This process consists of two sub-processes‚ light dependent and light independent. In a plant cell there is an organelle called the chloroplast. In each plant cell there

water and nutrients. * Each part of the plant has a specific function: * * leaves - carry out photosynthesis. * roots - anchor the plant & absorb water and soil nutrients. * stems - support the leaves and transport materials to other plant parts. * What does the plant use the glucose for? The plant uses sugars produced during photosynthesis to builts its structure. * Petiole - the stalk that attaches the leaf to the stem. * Covering the upper

Robinson BIO 204 Plant Physiology Monday‚ January 26‚ 2015 Brandy McFadden Process of Photosynthesis We all learned in elementary school that the suns provide nutrients and components that help plans grow. “As the name implies‚ photosynthesis is a process that uses light energy to synthesize something.” (Mauseth‚ 2014) That process is called photosynthesis. Photosynthesis is the process where plants use light energy from the sun. If we

are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants‚ plastids may differentiate

The overall goal of photosynthesis is to chemically change light into energy. • Because photosynthesis only occurs in plants‚ why is it essential to animal life? It is essential to animal life not only for nutrients from the plants but also because of the byproduct oxygen that is put out from the plants from the photosynthesis process. • What is the role

Theodor Wilhelm Engelmann was a German microbiologist whose 1882 experiment measured the effects of different colors of light on photosynthetic activity and showed that the conversion of light energy to chemical energy took place in the chloroplast. In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae.

respiration and oxygenic photosynthesis are two cellular processes that have evolved in similar ways. Cellular respiration is responsible for the process of ATP‚ meanwhile oxygenic photosynthesis is the process of turning light energy into food. It is evident that both of these processes have their own reactants‚ products‚ and biochemical pathways. Both of these processes have evolved from their primitive original state‚ but it is important to understand that oxygenic photosynthesis evolved before aerobic

Introduction: Photosynthesis can be defined as light energy being converted into chemical energy‚ which is a very important process for plants and other organisms. Light can be described in terms of light quantity and light quality. Both of these have an affect on photosynthesis. The more light a plant absorbs the more the plant is able to photosynthesize. This light is absorbed though pigments which have specific interactions with certain light waves (colors). The goal of my first experiment

some bacteria. A small number of bacteria‚ including the ancient Archaea group are capable of generating food from sulfur or other chemical reactions‚ but the majority of autotrophs rely on sunlight to carry out a process called photosynthesis. In the process of “photosynthesis”‚ specialized molecules capture carbon from the air and bind it to water using energy produced from sunlight. There are two classes of autotrophs: chemoautotrophs and photoautotrophs. Chemoautotrophs are able to “fix”
