Chapter 7 and 8 discuss and give in depth details on photosynthesis and cellular respiration. They are the exact opposites in what they set out to complete in the cells of a leaf. Photosynthesis takes light energy and separates it in the chloroplasts to create glucose. Cellular respiration breaks down glucose to provide energy for the cell. The similarities between them include overlap in some of the enzymes and products and reactants utilized. The differences include the cycles and steps taken to

Lab #2: Energy in Cell Virtual Lab - Week 3 NAME: ________________________________________ 1. What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During

The concentration of 1-kestose isomer increased steadily with time from 0 - 80 min. During this time‚ sucrose was significantly influencing the rate of 1-kestose formation and hence the optimum concentration of the 1-kestose isomer was observed at 80 min. After 80 min‚ the 1-kestose concentration gradually decreased. This was because the invertase active sites had become saturated with sucrose (substrate) or sucrose had been used up in the reaction. Therefore‚ there was a gradual decrease observed

oD 4.1 Respiration Why organisms undergo respiration What is respiration and why do we need it? Respiration is the process whereby energy is released from food molecules (most usually glucose). It takes place inside living cells‚ both eukaryotic and prokaryotic. The process takes place inside the cytoplasm and the mitochondria. Energy is used to synthesise adenosine triphosphate (ATP)‚ which acts as a short-term energy store in cells. All living organisms need energy to drive their

LAB 05B Momentous Design Proposal name :sonia malini Date of investigation: 8 September‚ 15 September 2009 Date of submission: 29 September 2009 Purpose The main purpose of the experiment is to investigate validity of the conservation of linear momentum from three main different types of momentum‚ namely: head on collision of equal masses‚ head on collision on unequal masses and exploding carts. Theory In the 17th century‚ Isaac Newton was the one who realized that the momentum is conserved

Lab 4: Plant Transpiration Project By Shelby Hyde Lab 030 Date Due: March 12‚ 2013 The Effect of Wind on the Rate of Transpiration Introduction: Transpiration is the process through which water is evaporated from plants. This serves many purposes‚ including thermoregulation and the diffusion of CO2‚ but most importantly creates a water potential difference which causes the mass flow of water and nutrients from the roots to the leaves of the plant. Transpiration is accomplished through structures

Title : Comparing the rates of pulmonary and cutaneous respiration in frogs Introduction Frogs are amphibians that live in moist environments to support one of their key mechanisms of respiration. Frogs have the ability to breathe many diverse ways‚ due to their unusual life cycle and aquatic and terrestrial environment. The Order Anura shows the extreme anatomical and physiological diversity. Many frogs use lungs to respire‚ bringing in air through their nares‚ mouth‚ into the trachea and then to

Fast Plants Lab Background Gregor Mendel is an Australian monk‚ who worked in a garden at a monastery. He experimented with pea plants‚ and soon became known as the father of genetics. The reason he studied pea plants was because they grow quickly‚ the traits can be easily observed‚ and the plant is easy to pollinate. Mendel’s method was to control the pollination of the pea plants and create offspring’s of the two plants that were pollinated together. Using self-pollination and cross pollination
