Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

LAB REPORT HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3:

the lower the gross primary productivity values. Variables: Control- The group with zero salt added. Dependent- Dissolved oxygen reading. Independent- The salt concentration in the water. Introduction: On the surface waters of lakes and oceans‚ plants are mainly unicellular algae‚ and most consumers are microscopic crustaceans and protozoans. Both the producers and consumers are very small‚ and they are easily contained in a liter of water. If you put these organisms in a bottle and turn on the

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source. Beaker #1 is six

INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants such as leaves‚ roots‚ stems‚ or fruits

found over range of continents and have common characteristics with plants and animals. There are many types of Biomes on earth. BIomes are distinct from habitats‚ because any biome can comprise a variety of habitats. In our lab we had figure out the major components in a biome. For example‚ like the weather‚ what animals live in it‚ plant life‚ etc… And answer key questions to why something happens in a Biome. And how species and plant life depend on each other to survive in this biome. In order to

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation of

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.
