Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables

Photosynthesis (pron.: /foʊtoʊˈsɪnθəsɪs/; from the Greek φώτο- [photo-]‚ "light‚" and σύνθεσις [synthesis]‚ "putting together"‚ "composition") is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. Photosynthesis occurs in plants‚ algae‚ and many species of bacteria‚ but not in archaea. Photosynthetic organisms are called photoautotrophs‚ since they can create their own food. In plants

Lab 2: Animal and Plant Cells Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells. Question: What are the differences between multi and single celled plant and animal organisms? Prediction: Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall‚ cell membrane‚ nucleus‚ chloroplasts‚ vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible

AP: CHAPTER 43: IMMUNE SYSTEM 1. List the two lines of nonspecific defense mechanisms with examples of each. • External defense‚ which includes the skin and mucous membranes in the body. • Internal defense which includes phagocytic cells and antimicrobial proteins. 2. What is meant by specific defense? Defense mechanisms are said to be specific because depending on which one they focus on one specific part of the body or a specific type of pathogen. 3. Give examples of “barrier defense

Protocol for Lab 5 – Aerobic Respiration Part 1 Isolation of Mitochondria from Cauliflower - Weigh 50g of rosettes cut from fresh cauliflower head. - Cut rosettes and place it on ice - Prepare juice extractor by placing ice and an empty 150 ml beaker into the right compartment. - Collect pulp from left compartment and record total volume of the extract. Approx. 20ml - Filter the pulp using six layered cheese cloth and collect it in a beaker sitting on ice. - Place two 50 ml test tubes

Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic compounds produced by geochemical processes‚ but that most of these original compounds were used up billions

Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of eukaryotes. These eukaryotes then evolved into protists‚ fungi‚ plants‚ and animals. As they evolved‚ so
