1. Flowering plants reproduce through flowers, which produce fruit containing seeds after pollination and fertilization.
2. Seeds can be dispersed in various ways including by air, water, explosion, birds, and animals to allow for the propagation of new plants.
3. The main parts of a flower include sepals, petals, stamens, and a carpel. Pollination, which is needed for fertilization and seed production, can occur through self pollination or cross pollination with the help of agents like wind or insects.

Asexual reproduction is a process in which new organism is produced from a single parent without the involvement of gametes or cells. Many unicellular and multi cellular organisms reproduce asexually.

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 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.

Seed is an important part of a flowering plant. They give rise to a new plant. They may be of different shapes, colours and sizes. They may be round, wrinkled, winged or hairy. They are in a dormant condition until they receive adequate sunlight, water, and soil. The growth of the plant from a seed is known as germination.

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” 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.

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?
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”.

2. Why plant has flowers?
❑When Plant produces flowers.
❑Flower last for few days
❑Part of the plant stays on the plant
❑This part give rise to fruit.
❑The seeds form inside the fruit.
❑The seeds give rise to new plant.
Flowers helps plant to reproduce to form new
plant.Hence it is called as Reproductive unit.
3. SEED DISPERSAL
• The process by which seeds are spread from one place to
the other by air, water, animals and birds is called
dispersal of seed or seed dispersal.
4.
5. •Seed Dispersal
•By Air
•Silk cotton, drumstick, Dandelions, poppy fruit, Chandelier, Maple seeds
•By Water
•Water Hyacinth, Coconut, Lily, Lotus , Mangrooves etc
•By Explosion
•Lady finger, Peas, Black gram
•By Birds
•Fruit plants
•By animals
•Grass
6. • Dandelions have parachute of hairs to help them
float to the air. Other seeds have thin papery
wings to help them blow away easily.
• The fruits of chandelier plant dry out and break
off. As the wind blows them along, the seeds fall
out.
• The poppy fruit forms a pepper pot with holes in
it. When the wind blows ,the seeds blown away.
• The seeds of the maple trees has wings that allow
the wind to lift and spin like a helicopter rotor
blades.
• Mangroves are trees that grow in salt water and
their seeds are called sea pencil float upright in
the sea until they are washed onto land.
• Bean pods dry out and explode in hot weather.
8. SEPALS-
Little green leaves that protect the flower bud
PETALS
Often brightly colored to attract insects to the
flower
STAMENS
This is male part of the flower - Stamen- It
consists of anther and filament. These are pollen
grains which are found in the anther.
CARPEL
This is female part of the flower - Carpel which
include stigma, style and lower part ovary
Ovary consists of ovules.
10. Pollination is of two types
(i) Self pollination
(ii) Cross pollination
SELF POLLINATION:
The transfer of pollen grain from anther to the stigma of same flower is
called self pollination.
CROSS POLLINATION
The transfer of pollen grain from anther of a flower to the stigma of another
flower of same kind is called cross pollination
11. Agent of pollination
Pollination by insects
Flowers pollinated by insect are usually coloured,
scented petals.Some flowers also have nectar,
sweet liquid where insect visit to feed on the nectar
The insects covered in pollen and carry the pollen grain .
Pollination by wind
Flowers pollinated by wind are not brightly coloured
and do not have scent.Wind pollinated flowers
make lot of pollen. The pollen blows in the wind
from the stamen of other flower
12. Why Pollinations?
Plant reproduce by seeds.T he pollen and eggs join to make seeds in
a plant in a process called Fertilisation.
Pollination bring pollen from the male stamens to the female carpel.
This allow the egg to be fertilised and seeds to form. Fertilisation
happen in the flowers ovary. Fertilisation happens if the pollen and
egg are from same kind of flower.After egg fertilised,
the petals and sepals die. The ovary grow and become fruits.
Seed inside the fruit.
