Cyanobacteria or cyanophyta is commonly known as blue-green algae which is a type of bacteria. The colour pigment they have is from phycocyanin along with chlorophyll. Chlorophyll is in all green plants, algae and also cyanobacteria which helps them absorb light to create energy to be able to perform photosynthesis. Cyanobacteria grows at the ocean shore or pools and ponds at their edges although they can be found in soil, water and salt water. Cyanobacteria live in sheets like films, but thin enough
The hormone cytokinin causes this after the exposure of light. Chloroplasts contain chlorophyll and due to this the plant turns green. 1.1 Research question For this experiment, I want to find out what will happen to cress seeds that are etiolising (growing in the dark) when they are then exposed to light. To conduct this experiment, I came
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy. The process of photosynthesis is
Photosynthesis takes place in the chloroplasts (the green pigment of the plant), during which green plants convert light to chemical energy and store the product in the bonds of sugar. For photosynthesis to successfully take place plants H2O, C2O, light and chlorophyll are needed. Photosynthesis doesn’t only provide nutriment to the plant; it also produces oxygen, which is absolutely essential to every living organism on Earth. Therefore photosynthesis is a crucial process and holds a very important role in the
photosynthesis rate will increase. This is because as light intensity increase, the rate of light-dependent reactions increase since light dependent reactions use light as an energy source. When light hits the surface of the leaf, it is absorbed by chlorophyll pigments. The light dependent reaction takes place in the chloroplast, more specifically the thylakoid membrane.
pigment is created by chlorophyll in the plant. 6 CO2 + 6 H2O –> C6H12O6 + 6O2 Carbon dioxide + Water –> Glucose + Oxygen Research question: How does the rate of photosynthesis change in Cabomba pond weed when the changing variable is the light intensity? Hypothesis: I predict that the closer the light gets to the cabomba pond weed the faster it produces oxygen. When it gets closer to the light source the photosynthesis reaction takes place faster because of the chlorophyll in the plant taking
Development is about growth and helping to grow different aspects, as together they create further growth. Development is vital in today’s society as it affects every aspect in everyday life. Certain factors have a huge influence on development or the lack thereof the need to improve development. The lack of development directly affects the economy. 1.2 Development in my understanding is to see, encourage, or make growth happen. Whether, it can be a slow progression or a rapid improvement. Development
1 Rhizosphere Interactions Jacob Griganavicius Robyn Dumalo Introduction Plants are the most important living organism on our planet today, without them; humans would most likely not be present on this planet. Plants are photoautotroph, which means they get energy from sunlight in order to change carbon dioxide (CO2) and water (H2O) into organic materials for all living organisms1 . The reason that plants are so important to humans is that they go through a main process to produce oxygen so
Climate change has serious negative impacts on agriculture crops production in Pakistan. This sector contributes 21 % of Pakistan’s economy. About 80% agricultural yield is produced by cultivation of land through the world largest integrated irrigation system. This report reveals that climatic condition in Pakistan causes of extreme temperature, less rainfall, variation in precipitation, rapidly glacier melting and increase in evaporation, releases of GHG emission, and crop water requirements. In
Title Which frequencies and type of light aided and affected the efficiency of photosynthesis or carbon dioxide consumption in a spinach leaf? Purpose The purpose of the experiment/lab was to observe the effectiveness of different lights during the process of photosynthesis. Background Photosynthesis is a biological process. It occurs in plants, algae and specified bacteria (prokaryotes). Photosynthesis is the process where plants, algae, and bacteria convert light energy into chemical energy.
Drinking Water Is the Way to Go Specific Purpose: To show to my audience the importance of water to our body and to encourage them to drink water more often. Central Idea: Many people may take drinking water for granted, but keeping hydrated can have a huge impact on overall health. Despite how crucial it is that people drink enough water, a significant amount of people may be failing to drink recommended levels of fluids each day. I. The Attention Step Water is virtually everywhere, from soil moisture
Ringworm is one of skin disease that is easily transmitted and affect the skin in general. Even some parts of the skin including the skin of the body, part of the nail and the skin of the head can be affected by ringworm. For all this skin disease certainly will lose confidence and also the impact of a very serious skin problems. What if ringworm is already attacking parts of the scalp that are difficult to cure. Ringworm diseases generally can be cured with regular ointment type sold in pharmacies
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases. Background Information: In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from
Aim: How does light intensity affect the rate of photosynthesis in Elodea (pondweed)? Introduction: In this experiment, we were testing the rate of photosynthesis in elodea. For a plant to photosynthesize, it needs carbon dioxide and water and sunlight, a factor of photosynthesis. In order for us to measure the rate of photosynthesis, we needed to measure the products that were made, glucose and oxygen. As oxygen was a visible product, we counted the oxygen bubbles made when we moved the source

Present time medicinal plants being the effective source of medicines, either it can be modern or traditional medicines, the advantage of medicines are they are useful for health. Guava contains broad spectrum of phytochemicals including polysaccharides, vitamins, essential oils, minerals, enzymes, proteins, sesquiterpenoid alcohols, triterpenoid acids, alkaloids, glycosides, steroids, flavanoids, tannins, saponins. Psidium guajava linn or guava is very rich in antioxidants and vitamins and also
Water 1. How are the properties of water important for its roles in living organisms? Water is commonly called the universal solvent because it can dissolve more substances than any other liquid. The chemical composition of water means that it is effective as a solvent – water molecules have a polar arrangement which is due to the difference in electronegativity of oxygen and hydrogen. Since oxygen is highly electronegative it attracts the electron pairs in the covalent bonds to it, the oxygen
