structures of multi-layered sheets of microorganisms (microbial mats) that form in limestone. Stromatolites generally form from the trapping and binding of particles by microorganisms e.g. algae and bacteria‚ and grow upward to get light from photosynthesis. Stromatolites provide scientists with some of the oldest records of early life on earth found from fossil remnants dating back to more than 3.5 billion years ago. Name the organism that forms Stromatolites and how they form them: Cyanobacteria

April 1‚ 2012 Professor Kelli Roberts Energy‚ Metabolism‚ and Cells Photosynthesis is the process that pretty much every organism on earth needs‚ because of the nutrients produced which is needed in order to live. Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis‚ it takes the sun’s energy and chlorophyll found in chloroplasts in the green

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

and close to allow the absorption of carbon dioxide and release of oxygen. Photosynthesis is the process by which plants convert sunlight into suitable energy. (http://www.yourdictionary.com/photosynthesis) Photosynthesis actually takes place in the stomata where carbon dioxide and oxygen enter and leave the plant. Chlorophyll is the green pigment of leaves and plants that’s in charge of absorbing light for photosynthesis. (http://dictionary.reference.com/browse/chlorophyll) All chlorophyll plants

Stomata are tiny pores found on the epidermis of the leaf‚ surrounded by guard cells. [1] Their main function is gas exchange [1] for photosynthesis and respiration. The development of stomata on the leaves of a plant is determined by interaction between different genes and environmental factors. A few studies have been conducted in order to establish a relationship between stomatal densities and given environmental factors. Research has shown that stomatal densities are controlled by environmental

Lab Report: Photosynthesis Name: Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? In this lab I will perform experiments to explain photosynthesis. I will answer questions like what does photosynthesis do and how does photosynthesis work? Hypothesis After reading the lab instructions (but before starting the lab) record your best educated guess about what will happen in the experiment. Explain

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: Plants transpire the least when it is dark and there is lots of humidity. JUSTIFICATION: Photosynthesis does not occur without light and the humidity prevents

You plan to separate these compounds using paper chromatography with a non-polar solvent. Predict the location of the two bands relative to the solvent front. Explain your answer. Since compound A is probably more polar than compound B‚ compound B will move further in the chromatography. Since the solvent is non-polar
