Plants require light to grow and reproduce through photosynthesis. Photosynthesis occurs in two stages - the light reactions where light is converted to chemical energy, and the Calvin cycle where CO2 is incorporated into organic molecules. It takes place in the chloroplasts in the mesophyll cells of leaves. The light reactions occur in the thylakoid membranes and use water, carbon dioxide, and light energy from chlorophyll to produce oxygen, ATP, and NADPH. The Calvin cycle then uses these products to fix carbon and produce sugars. Different plants have photoperiod responses and will flower depending on the length of daylight or darkness they experience.

Everything about photoperiodism from scratch to smart, from the oldest models to the latest models as well as proposed one, exclusive and elusive illustrations and models for proper understanding
photoperiodism its discovery,significance,classifications,mechanism,critical day length,quality of light, night break phenomenon,phytochrome.florigen,floering genes, circadian rhythm
Plants create their own food through the process of photosynthesis, making them autotrophs. Additionally, the process' end result is referred to as a photosynthate or photo-assimilate. In plants, the phloem is a conducting tissue that carries photosynthate (food) to every part of the plant. While storage or the point of use is referred to as the Sink, the source of production or manufacturing is referred to as the Source. The source and sink connection notion is explained in the slides. The mechanisms cover these and other crucial aspects of the topic.

Effects of Light Intensity on Tissue CulturesHuda Nazeer
This presentation is about how light intensity affects tissue cultures, based on an experiment that was carried out in the lab. It highlights the importance of light and source of light, the effects of light intensity, the problems that are faced in the lab, and the possible improvements that can be done.
WHAT IS PHOTOSYNTHESIS?, IMPORTANCE OF PHOTOSYNTHESIS, STRUCTURAL FEATURE OF LEAF ADVANTAGE FOR PHOTOSYNTHESIS,LEAVES AND LEAF STRUCTURE,CHLOROPHYLL, TYPES OF REACTIONS, LIGHT REACTION AND DARK REACTION, CYCLIC AND NON-CYCLIC PHOTOPHOSPORYLATION, MECAHANISM OF ATP SYNTHESIS, SCHEMATIC PRESENTATION OF LIGHT REACTION, CRASSULACEAN ACID METABOLISM (CAM), C3 AND C4 PLANTS, FACTORS AFFECTING RATE OF PHOTOSYNTHESIS, INTERNAL FACTORS AND EXTERNAL FACTORS,
Photosynthesis is a biological process used by many cellular organisms to convert light energy into chemical energy, which is stored in organic compounds that can later be metabolized through cellular respiration to fuel the organism's activities.
Students will be able to discuss everything concerns Photosynthesis and its limiting factors. Also they will study the light dependent and light independent reactions by which the plant's food is produced!
This presentation discusses the way energy flows and is distributed all throughout the ecosystem, from one member to another. This details how one organism becomes an essential necessity for another and how abiotic components play their role as supportive elements for life.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

14. An excited electron is unstable and will drop back to the ground state and release its excess energy in the form of heat and fluorescence
15.
16. Linear Electron Flowthe flow of electrons through the photosystems A photon is absorbed by a pigment molecule in the light harvesting complex, exciting an electron As one electron falls back to ground state, another one rises This continues until the energy reaches the pair of chlorophyll a molecules in the reaction center complex in photosystem II An enzyme splits water in photosystem II into electrons, hydrogen ions, and oxygen The splitting of water molecules facilitates the flow of electrons through the electron transport chain to photosystem I to replace the electrons that were excited by light energy ATP is then synthesized from the energy created from the movement of electrons Light energy is transferred from the light harvesting complex pigments to the reaction center complex of photosystem I Photoexcited electrons move from the primary electron receptor of photosystem I to the second electron transport chain This is a light dependent reaction, creating NADPH and ATP which are then used in a light independent reaction, also known as the Calvin cycle
27. The amount of energy a photon has is related to how long the wavelength is
28.
29. Photoperiodism The reaction of plants in relation to the length of the day Plants use it to measure the seasons and to coordinate seasonal events such as flowering Plants can be described in relation to their photoperiod responses as short-day, long-day, and day neutral The length of daylight effects vegetative growth and reproductive activities in plants The length of darkness a plant experiences plays a more crucial role in whether a plant flowers or not
30.
31. Short day plants only form flowers when the length of the day is less than about 12 hours
33. Chrysanthemums, poinsettias, and goldenrods are examples of short day plantsThe chrysanthemum is in demand all year, which is why florist have to regulate their flowering using artificial lighting
34.
35. These flowers only bloom when they receive more than 12 hours of light each day
36. The best time of the year for long day plants to flower is late spring or early summer, when the days are longer (this is opposite in the southern hemisphere)
37. Many garden vegetables are long day plants such as potatoes, lettuce, and barleyAfter the summer solstice days become shorter, and long day plants are harvested shortly after.
38.
39. They flower regardless of day length, but flower earlier and more often with longer days
40. More often, the age of the plant, and temperature around it effect flowering
41. Beans, tomatoes, and roses fall into the category of day neutral plantsRoses are the most popular day neutral flowers
