Flowers have distinct structures that allow for reproduction. A flower consists of a pedicel, bracts, receptacle, perianth, hypanthium, nectaries, androecium, and gynoecium. The androecium refers to the male organs or stamens, while the gynoecium refers to the female organs or carpels. Flowers can be complete or incomplete, perfect or imperfect, and plant sex can be hermaphroditic, monoecious, or dioecious.

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to bring beauty to their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. In this lesson you will learn about : 1) Flower - Definition & Functions 2) Floral Symmetry 3) Pedicellate & Sessile Flowers 4) Insertion of Floral Leaves on the Thalamus 5) Parts of a Flower 6) Some Important Terms related to Flowers 7) Floral Whorls - Calyx, Corolla, Androecium and Gynoecium 8) Placentation 9) Inflorescenece I hope this document is helpful to you. Please share the document with your friends if you think this will benefit them. Get ready for the next lesson. Thanks.

Parts of a Flower Sepals Petals Receptacle Pistil Stamen Stamen The stamen (plural stamina or stamens) is the pollen-producing reproductive organ of a flower. Filament- Supports the Anther Anther- Produces Pollen Grains Pistil The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates. Peduncle The stalk of a flower. Types of Flowers Complete Flowers- have both male and female parts Incomplete Flowers- have either male or female parts but not both. Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds. How Are Plants Pollinated? Bees Birds Wind Humans Animals How Are Flowers Useful to Us? Flowers are not just beautiful to look at, but they also serve a vital role in our ecosystem. Flowers help our ecosystem flourish and attract a plethora of life to the area and facilitate the expansion of our environment. If flowers are cut down or destroyed before pollination can occur, that particular species has a high chance of dying off in that area. In addition, local wildlife will also vanish in that area since they would have no food. Flowers help keep the ecosystem growing and provide new plant life, as well as help sustain local insects and birds.

angiosperms morphology of a flowering plant parts of flowering plant. What are angiosperms? Angiosperms are plants that produce flowers and bear their seeds in fruits. They are the largest and most diverse group within the kingdom Plantae, with about 300,000 species. Angiosperms represent approximately 80 percent of all known living green plant. The outstanding and most significant feature of the flowering plants (and that which sets them out from other vascular plants) is the flower. Understanding the flower structure and names of the parts is important as it is the most important set of characters for both recognizing and keying species, genera, families, etc. Floral parts (terms & illustrations) 1. Peduncle / pedicel - floral stalk 2. Receptacle - the modified shoot or floral axis 3. Sepals / calyx - the outer most whorl; collectively all sepals are called the calyx. Sepals are typically green and protect the inner floral parts in buds 4. Petals / corolla -the next whorl, collectively all petals are called the corolla. Petals are typically brightly colored and and assist in attracting pollinators. The sepals and petal combined are called the perianth. If the perianth parts cannot be differentiated into sepals and petals, that is, that look so much alike, then they are called tepals. 5. Stamens (androecium) - the next whorls, each stamen has two parts: filament and anthers. Androecium or "male house", the name for all the stamens. The anthers house the microsporangia which undergo meiosis and produce pollen grains. 6. Nectaries - are often associated with flowers, they are found at the receptacle and offer a reward to animal pollinators. 7. Carpels (gynoecium) - The innermost and final whorl is composed of all the carpels and is the site for pollination and fertilization. Collectively all carpels are called the gynoecium: "female house". Carpel has three parts: stigma which receives pollen, the style which is the a slender region specialized for pollen tube growth and the ovary which is an enlarged basal portion and surrounds and protects the ovules. The structure(s) in the center of the flower are often referred to as the pistil(s). Pistil is a layman's term for "flask-shape" structure, so anything with that structure is called a pistil. This is one of the more confusing parts of the flower; more on this below.

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.

Operation Blue Star - Saka Neela Tara

Balvir Singh

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup. The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Break the cycle of negative Thoughts

Col Mukteshwar Prasad

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
