Sexual reproduction involves two parents fusing gametes to produce offspring that differ from the parents, allowing for variation. Asexual reproduction involves one parent and identical offspring through budding, stolons, or runners. Plants reproduce sexually through flowers containing male stamens and female carpels. Pollination transfers pollen grains which fertilize ovules in the carpel, forming seeds within fruits. Seeds then disperse through wind, hooks, or animal consumption to germinate away from the parent plant.

The document discusses plant reproduction and strategies for seed dispersal. It explains that flowers evolved to facilitate sexual reproduction in plants and allow plants to pass their genes to offspring. Various dispersal mechanisms are described, including wind dispersal for seeds with wings or plumes, water dispersal for buoyant seeds, and animal dispersal for seeds contained in fleshy fruits or attached to hooks/barbs. The mistletoe plant is highlighted as having evolved a mutualistic relationship with mistletoebirds, which eat the fruit but disperse intact seeds in their droppings, aiding the plant's dispersal.
Unit 23 Plant Reproduction
1. Plant life cycles alternate between a sporophyte phase and gametophyte phase through the process of meiosis and fertilization.
2. The sporophyte phase produces spores via meiosis while the gametophyte phase produces gametes via mitosis which can fuse during fertilization.
3. Flowering plants undergo a double fertilization process within flowers where one sperm cell fertilizes the egg to form the embryo while another sperm cell fuses with polar nuclei to form endosperm.

Plants reproduce both sexually and asexually. Sexual reproduction involves a male and female parent producing offspring that are genetically different, while asexual reproduction involves one parent producing offspring that are genetically identical clones. There are advantages to each type of reproduction depending on the environment and situation. Asexual reproduction is simpler and requires less energy, making it preferable when colonizing new areas or in harsh environments where sexual reproduction may not be successful.

Plant reproduction
Plant reproduction can occur through asexual and sexual means. Asexual reproduction involves only one parent and produces genetically identical offspring through processes like budding, fragmentation, and spore formation. Sexual reproduction involves male and female gametes from two parents, producing offspring with new combinations of genes. In flowering plants, sexual reproduction takes place through flowers, which contain stamens that produce pollen and carpels containing ovaries and eggs. Pollination leads to fertilization and seed formation, and seeds are then dispersed and can germinate to form new plants.

Reproduction in flowering plants (sexual reproduction)Shashi kumari,Delhi university,Amity university,JNU New Delhi
Flowering plants reproduce sexually through flowers. Flowers contain male stamen that produce pollen and female pistils. Fertilization occurs when pollen is transferred, or pollinated, to the stigma of the pistil. Pollination can be self-pollination within a flower or cross-pollination between flowers. After fertilization, the ovary develops into a fruit containing seeds. Seeds are dispersed by various methods and may germinate to form a seedling with root, shoot, and leaves developing from the radicle, hypocotyl, and epicotyl respectively.Grade 7 L 11 Reproduction in plants.pdf
Reproduction in plants can occur through asexual and sexual reproduction. Asexual reproduction involves a single parent and produces offspring that are genetically identical clones.

It also summarizes the different types of reproduction in plants including self-fertilization, cross-fertilization, and various forms of asexual propagation.
Sexual Propagation Seed Propagation (Version 2)
Sexual propagation uses seeds to produce offspring with genetic combinations from both parents. It involves pollination, where pollen is transferred from the anther of a flower to the stigma, leading to fertilization and seed formation. Seeds can be from self-pollination, using pollen from the same plant, or cross-pollination, using pollen from a different plant. The seed contains an embryo with one or two cotyledons - monocots have one and dicots have two. Sexual propagation has advantages like being easy and allowing for diversity and hybridization, but seedlings take a long time to flower and fruit and are not always true to the parent plant.

This document provides steps for balancing a chemical equation. It first emphasizes that balancing the reaction is the most important step for stoichiometric calculations. It then lists the two steps for balancing a reaction: 1) Count the number of atoms of each element in the reactants and products and list them. 2) Adjust the coefficients of the reactants or products so that the number of atoms for each element are equal on both sides of the equation. Balancing the reaction ensures the stoichiometric coefficients are correct for accurate stoichiometric calculations.
Collision Theory and Chemical Reaction Rate.pptx
1. Collision theory states that for a chemical reaction to occur, reactant particles must collide with sufficient kinetic energy and be properly aligned.
2. Three factors that determine if a collision results in a chemical reaction are: the particles must collide with enough energy to break bonds (activation energy), collide with proper orientation, and come into contact with one another.
3. Reaction rate is a measure of how quickly or slowly a chemical reaction occurs and is affected by factors like concentration, temperature, surface area, and catalysts which influence the frequency and success of particle collisions.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 2. Sexual & asexual reproduction Sexual reproduction: Two parents Fusion of a female & male cells (gametes) Parent & offspring are not identical Slower Variation is present in the same species Asexual reproduction: One parent only No gametes are produced Parent and offspring are identical Faster No variation
- 3. Examples of asexual reproduction. Budding in yeast Nucleus replicates Nucleus migrates to one end Part of the cell grows into a bud The bud separates creating a new cell
- 4. Examples of asexual reproduction. Vegetative reproduction in potato plants
- 5. Examples of asexual reproduction. Runners in strawberry
- 6. Sexual reproduction in plants To reproduce sexually plants have male and female reproductive organs in their flowers. The male part is called the stamen The female part is called the carpel
- 10. POLLINATION It is the transfer of pollen grains from the anthers to the stigma Pollinating agents Insects Wind
- 11. Differences between insect & wind pollinated flowers Insect pollinated Wind pollinated Have large colored petals with guide lines Have a scent Have a nectary on which insects feed Have a sticky stigma for pollen grains to stick on it The female and male organs are enclosed in the flower Pollen grains are larger with spikes to hold on insect body Have small green petals, no guide lines Have no scent Have no nectary Have a feathery stigma to catch the pollen in the air The female and male organs are hanging outside the flower Pollen grains are smaller & light weight to be carried by wind
- 12. POLLEN GRAINS AS SEEN UNDER THE MICROSCOPE Can you tell which belongs to insect pollinated flowers / wind pollinated flowers?
- 13. FERTILIZATION It is the joining of male and female cells to produce a zygote. Ovary Fruit Ovary wall Fruit cover Ovule Seed
- 14. Seed structure
- 15. Seed-fruit dispersal If a seed lands next to the parent plant and germinates it will compete with the parent plant for nutrients in the soil. Most plants developed methods to scatter/disperse their seeds to ensure they land further away from the original plant. There are 2 main methods of seed dispersal: Wind dispersal Animal dispersal
- 16. Wind dispersal Parachute e.g. dandelion Winged fruits e.g. Acer
- 17. Animal dispersal Hooked fruits e.g. Burdock and others
- 18. Animal dispersal Other fruits are large coloured and fleshy/juicy to attract animals to eat them, swallowing the seeds at the same time. The seeds have hard indigestible testa that pass out with faeces in a new area away from original plant. Example of such fruits: apple, acorn, strawberries…etc.
- 19. Seed germination Once a seed falls onto a suitable surface it starts to grow. Conditions required for seed germination: 1. Suitable temperature 2. Oxygen 3. Water
