fifteen minutes intervals‚ we weight the egg and record that the weight decreases. In our second experiment‚ we use three slices of aquatic plant Elodea and add pond water one leaf‚ distilled water for the second and 20% NaCl for the third‚ then observe the cells of each leaf with a compound microscope. Under microscope‚ chloroplasts (green organelles) in Elodea tend to bound to the cell wall in pond water‚ spread all over the cell in distilled water‚ pull away from cell wall in 20% NaCl. In our last

Aquaponics system is a food production system that combines conventional aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria

Autotrophic cells capture free energy through photosynthesis and chemosynthesis. Photosynthesis traps free energy present in sunlight that‚ in turn‚ is used to produce carbohydrates from carbon dioxide. Chemosynthesis captures energy present in inorganic chemicals. Cellular respiration and fermentation harvest free energy from sugars to produce free energy carriers‚ including ATP. The free energy available in sugars drives metabolic pathways in cells. Photosynthesis and respiration are interdependent processes

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

The Effect of Light Intensity on Photosynthesis and Transpiration Inna V. Raymundo BOTANY I Section V-6L August 29‚ 2012 ¹A scientific paper submitted in partial fulfillment of the requirements in Botany I laboratory under Dr. Nonnie Bautista‚ 1st sem‚ 2012-2013. ABSTRACT Photosynthesis and transpiration both play important roles in plants. But there are factors which affect the rate of photosynthesis and transpiration. The external factor that was identified is the

oxygen. It’s a series of electrons carriers in the membrane of the mitochondria. Photosynthesis: • What is the overall goal of photosynthesis? Photosynthesis is a process whereby plants‚ algae and bacteria convert light energy in to chemical energy‚ using carbon dioxide and water. • Because photosynthesis only occurs in plants‚ why is it essential to animal life? Photosynthesis is important for animals because the plants produce the sugar they need as a vital

Research question : How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into

PLANT SYSTEMS QUESTION 1979:L. PETERSON/AP BIOLOGY In relation to plants‚ describe in detail one way of: a) measuring the rate of transpiration b) measuring the rate of photosynthesis c) separating pigments Essay : Transpiration is the loss of water vapor from land plants into the atmosphere‚ causing movement of water through the plant from the soil to the atmosphere via roots‚ shoot and leaves‚ which occurs mainly through the stomata. Factors which can affect the rate of transpiration are
