Lab Design Research question: How does temperature affect on the rate of photosynthesis? Variables: Independent variables: temperature of water where the elodea(plant) is going to be placed Dependent variable: the amount of oxygen produced by photosynthesis reaction Control variables: Light concentration entering the beaker Length of the plant Volume of the water to be precise And of the NaHCO3 What is the variable to be controlled. Why does it need to be controlled. How will you

Sugarcane is one of the world’s major food-producing C4 crops‚ providing about 75 % of sugar produced in the world for human consumption (Souza et al. 2008). World sugarcane production is close to 1.9 billion tonnes per annum and is concentrated in tropical regions‚ particularly developing nations in Latin America‚ Africa and Asia. India is the second largest producer of sugar after Brazil with a global share of 17% in 2014-15. Over five million farmers are involved in the cultivation of sugarcane

with what you observed for tomato plants? With both plants the photosynthesis rate increased while the light intensity increased. 2. Photosynthetic saturation is the maximum rate of photosynthesis. What value of light intensity produced photosynthetic saturation in corn leaves? 804 Lab Summary Address the following points in a 100-to 200-word summary: The purpose of this lab was to figure out the reactions of photosynthesis as the light intensity increased in tomato and corn plants.

Role of Stomata & Control Stomata : a pore found in the epidermis of plants which are used to control as exchange Main function of stomata : Allow enough C02 to enter the leaf to optimize photosynthesis‚ while conserving as much water as possible Structure of stomata * Each stomata consists of a stoma (minute pore) which are surrounded by 2 guard cells. * Stomata closes and opens according to the turgidity of the guard cells * Stomata also allows for cooling of the leaf by loss

In the Kingdom Exploration lab‚ five different organisms were observed under a microscope‚ (Yeast‚ Paramecium‚ Elodea‚ Daphnia‚ Euglena). Each of these organisms is apart of one of the six kingdoms‚ (Eubacteria‚ Archaebacteria‚ Fungi‚ Protista‚ Plantae‚ and Animalia) which are apart of three domains‚ (Archaea‚ Bacteria‚ and Eukarya). In this lab‚ however‚ none of the organisms observed were archaea or bacteria. Also‚ all the organisms were eukaryotes‚ not prokaryotes‚ which are organisms without

ADAPTATIONS * Define the term adaptation and discuss the problems associated with inferring characteristics of organisms as adaptations for living in a particular habitat. An adaptation is any feature or characteristic that helps an organism survive in its environment. Adaptations can be classified as either structural‚ physiological or behavioural. When studying organisms and relating the chances of survival to body structure‚ physiology and behaviour‚ biologists are always wary of inferring

all examples of organisms in the kingdom fungi. The kingdom of the plants is the second largest kingdom. The plants are very complex multicellular organisms. They contain chlorophyll‚ which helps them prepare their own food by the process of photosynthesis in which plants convert energy from sunlight into food. This kingdom includes all types of plants like herbs‚ shrubs‚ trees‚ flowering and non flowering plants. The biggest kingdom is the kingdom of the animals. The animals are the most complex
