Tutorial Questions 1) Basics of photosynthesis: a. Review the anatomy of the leaf and the cellular locations and organelles involved in photosynthesis. The outside of the leaf is covered in a waxy layer that helps prevent water loss called the cuticle. On the underside of the leaf there are small pores called stomata, which take in carbon dioxide to convert into sugar. Inside the leaf, water is transported through tubes called xylem. Photosynthesis occurs in the mesophyll (interior) layer

When it comes to photosynthesis and semiconductor-base solar cells they have many similarities as well as differences. In this paper I will explain to you exactly what they are. I will also point out how the laws of thermodynamics apply to both processes. One major similarity between photosynthesis and semiconductor-based solar cells is that they both require solar energy or sunlight for the process to begin. Photosynthesis’ main function is to transform solar energy into the chemical energy of

Influencing how energy flows through this ecosystem is the fact that most f the plants living mass is above ground. There are plenty of cycle in the rainforest that make sure the flow of energy and nutrients through this ecosystem is continual. Photosynthesis is the process which energy is harnessed from the sun and used along with carbon dioxide and water to produce energy and food. This allows plants to provide food for the wildlife by distributing the energy. This cycle is completed when plants

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Is the oxygen requiring reaction occurring in mitochondria, that break down the end product of glycolysis into carbon dioxide and water while capturing large amounts of energy as ATP. The three stages of cellular respiration are 1, glycolysis, 2. citric acid cycle and 3. electron transport.

a. 1. redox reactions means the transfer of electrons . In a redox reaction, the loss of electrons from one substance is called oxidation, and the addition of electrons to another substance is known as reduction. In photosynthesis, the reaction is  Water is split, and electrons are transferred along with hydrogen ions from the water to carbon dioxide, reducing it to sugar. Because the electrons increase in potential energy as they move from water(H-O bond) to sugar(C-H bond), this process

carbohydrates, is called photosynthesis. Can the energy of the sun be harnessed by humans to create energy? It can be and it is through the use of solar cells. Photosynthesis and solar cells are similar, yet different in a few ways. Creating Our Own Energy Humans have figured out how to use the power of the sun for energy. Using Solar panels containing semiconductors, we can turn the sun into electricity, a very popular form of energy. In this way, photosynthesis and solar cells are similar

Tutorial #4 -- Photosynthesis: the basis of life ____________________________________________________________ ___________________ 1. Basics of photosynthesis: a. Review the anatomy of the leaf and the cellular locations and organelles involved in photosynthesis. A leaf consists of waxy cuticle layer with stoma surrounded by guard cells, xylem vascular bundle, and a mesophyll. The chloroplast is located within the mesophyll cells. The stroma and thylakoids are located inside the chloroplast

Keondre Masters New Growth Imagine a flower with no roots would it grow? The answer is no, a plant is more complicated than that. A plant is made up from different sections which each section plays a role in the growth and the maintaining of the plant. The plant is made up of four or five sections depending on the plant, the root, the stem, the leaves, the flower, and the fruit. Without those following ingredients there would be no plants, no trees, and no air to breathe. Realize how important
