Characteristics of angiosperm |
|
Answer» Are you impressed byy answer CharacteristicsAngiosperms are able to grow in a variety of habitats. They can grow as trees, shrubs, bushes, herbs, and small flowering plants. Some of the characteristics of angiosperms include:All angiosperms have flowers at some stage in their life. The flowers serve as the reproductive organs for the plant, providing them a means of exchanging genetic information.Angiosperms have small pollen grains that spread genetic information from flower to flower. These grains are much smaller than the gametophytes, or reproductive cells, used by non-flowering plants. This small size allows the process of fertilization to occur quicker in the flowers of angiosperms and makes them more efficient at reproducing.All angiosperms have stamens. Stamens are the reproductive structures found in flowers that produce the pollen grains that carry the male genetic information.Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.Angiosperms have carpels that enclose developing seeds that may turn into a fruit.A great advantage for angiosperms is the production of endosperm. Endosperm is a material that forms after fertilization and serves as a highly nutritional food source for the developing seed and seedling. |

Ice is a solid but it floats on water |
|
Answer» Ice floats because it\'s density is 9% lesser than that of water When water freezes to form ice then the number of empty spaces are formed due to which its volume increases so its density decreases and it floats in water Because of its cage structure the volume is more than its mass as the density of water is greater than the density of ice. Ice is a solid but is hollow inside containing a lot of pores Because the density of ice is less than water Because it is less denser than water. As it has many pores in it and the water entes inside the ice and it floats |

Definition of manure and fertilizer |
|
Answer» Sahi ha Manures:\tManures are natural fertilizers. They are bulky sources of organic matter which supply nutrients in small quantities but organic matter in large quantities.\tManures are prepared by the decomposition of animal excreta and plant waste. Manures include farmyard manure (FYM), compost, green manure etc.Fertilizers: Fertilizers are commonly produced plant nutrients. Fertilizers supply nitrogen, phosphorous and potassium. They are used to ensure good vegetative growth, giving rise to healthy plants. |

What is a irrigation |
| Answer» Irrigation is the process by which water is supplied to the crops. The frequency of irrigation varies from season to season and crop to crop. Plants contain nearly 90% water, and need water for proper development of flowers, fruits and seeds. Irrigation can be done by two methods - Traditional methods and Modern methods. Some of the traditional and modern methods are elucidated.*Traditional methods of irrigation require animal and human labour to draw water. these are the cheapest methods available and are still in use. These include moat, chain pump, dhekli and rahat.*Modern methods are the irrigation methods which are efficient in supplying water to the crops. They help us to use water economically without wastage. They include drip irrigation and sprinkler system which require power from solar energy or biogas. | |

What are theain characters of gymnosperm ? |
| Answer» Some of the most important characters of gymnosperms are as follows:1. Habit:The living gymnosperms are woody, evergreen (except Larix and a Taxodium) perennials grow as trees or shrubs. Tallest trees are Sequoia sempervirens (366ft) and S. gigantia (342ft).2. Occurrence:The living members are founding in colder regions of earth where snow (not rain) is the source of water. Only the members of cycadales and gnetales thrive in warm dry climate.ADVERTISEMENTS:3. The dominant plant body is sporophyte (2n) which may be dioecious or monoecious. Gametophytes are inconspicuous and endosporic i.e. develop with the spores.4. Sporophyte differentiated into — root, stem and leaves.Root system:Tap root system is exarch and diarch to polyarch. Besides tap root, coralloid roots (in cycads) and mycorrhizal root (in coniferals) present.ADVERTISEMENTS:Stem: Erect, generally branched (Cycas is un-branched)Leaves:Dimorphic i.e. 2 types, foliage and scale leaves.5. Xerophytic Traits:Gymnosperms are xerophytes in nature due to presence of thick bark, thick hypodermis, thick cuticle, scales leaves, sunken stomata, transfusion tissue, etc. In some cases leaves modified into needle-like, scale like or small leathery. These are the adaptations to combat water stress in air and colder regions.6. Xylem:Composed of xylem parenchyma and tracheids with bordered pits. Vessels are absent (exceptin Gnetales).7. Pliloem:Composed of sieve cells and phloem parenchyma but companion cells absent.8. Heterospcry:The gymnosperms are heterosporous, means 2 types of spores produced i.e. haploid microspores and megaspores. Microspores produced within micro-sporangia while megaspores produce within megasporangia (nucellus) of ovules. Both types of sporangia are formed on special leaf-like structures called sporophylls (microsporophylls and megasporophylls).9. Cones or Strobili:Sporophylls are spirally arranged along an axis to form compact cone or strobili i.e. male or pollen cones and female or seed cones but in Cycas female cone is loosely arranged called lax.10. Ovules:Naked, sescile, geneiallyorthotropous, and unitegmic or bitegmic (in Gnetum).ADVERTISEMENTS:11. Pollination is anemophillous i.e. by wind.12. Fertilization is siphonogamous i.e. male gametes carried to female gametes by means of a pollen tube. Double fertilization, a feature unique to angiosperms, is absent in gymnosperms, but found in Ephedra. After fertilization, Zygote develops into embryo and ovules become seed.13. Endosperm or female gametophyte formed before fertilization and is always haploid. (But triploid in angiosperms.)14. Embryo development is meroblastic i.e. develops from a small part of zygote.15. Most members show polyembryony i.e. development of more than one embryo, but only one survives at the end.16. Cotyledons 2 (in Cycas) or many (in Pinus 2-14).17. Cambium form secondary wood which is monoxylic (soft and porous) or pycnoxylic (hard and compact)18. Connecting Links:The lower gymnosperms like Cycadales resemble pteridophytesin absence of vessels and wood fibers whereas higher gymnosperms like Gnetales and Coniferales resemble angiosperms. | |
