Mam what is function of germ pore ? Please answer me mam

[@NACBiology]

The germ pore is an opening in the pollen grain through which the pollen tube develops during fertilization. It allows the entry of water and nutrients, supporting the growth of the pollen tube towards the ovule.

[@KESHAVA.VIMALA]

Meaning of integumented megasporangium

[@NACBiology]

means an ovule in plants. It is the structure that contains the megasporangium (which holds the megaspore) and is surrounded by one or two protective layers called integuments. These integuments protect the developing embryo and help in the formation of seeds after fertilization.

[@laxmihs4148]

Mam zygote which is 2n in number is further converted into embryo know mam ?.

Mam doubt in a seed of maize scutellum is considered as cotyledon because it a)protects the embryo b)contains food for embyo c)absorbs food meterial and supplies them to the embryo d) convens selt into monocot leaf

[@AnushaAnusha-xj2rp]

Which one correct mam how

[@NACBiology]

Ok.. here it is and let me know what is the answer. In maize (corn) seeds, the scutellum is a specialized cotyledon that primarily functions to store and supply nutrients to the developing embryo as it germinates and establishes itself.

[@mallammaganiger9672]

Thank u so..... much mam

[@puneethkumar8592]

Perispermic seed Ex: 1)pepper 2)Beet Pepper ok mam what about beet,, beet is a root right?

Mam,, pistil of a flower can prevent germination and further post pollination events if pollen grain is of incompatible or wrong type,, then how desired hybrids can produce??

[@NACBiology]

Even though some plants reject their own pollen, breeders can still create desired hybrids by carefully choosing plants with different traits to cross-pollinate. This way, they ensure the plants mix their traits and produce new types with specific features.

[@AdithyaNS-xh8ne]

Mam what about thulsi plant , self pollination or cross pollination . Please explain

[@NACBiology]

Self-pollination occurs when pollen grains from the anther of a flower land on the stigma of the same flower or another flower on the same plant. In the case of Tulsi, the structure of the flower promotes self-pollination.

[@ChandanaNaik-j9y]

Mam your explanation is very beautiful and useful ❤

[@SANJAY.M93]

Mam Ovule includes integuments?

[@NACBiology]

yes

[@PriyaRaj-oh6ll]

Thank you mam your teaching is very beautiful 😍

[@prakashs1576]

Mam out breeding devices can prevent only autogamy why not geitenogamy which is the genetically example fon self pollination

[@NACBiology]

Outbreeding devices, such as dioecy or dichogamy, prevent autogamy by physically separating male and female reproductive organs. However, geitonogamy (pollination between flowers of the same plant) can still occur because it involves transfer of pollen between different flowers on the same plant, not between organs of the same flower.

[@prasannakhavasi9117]

Mam this is very helpfull 🚩❤

[@sathyasathya524]

Mam what is the meaning of this line nuclear division are not followed immediately by cell wall formation

[@NACBiology]

It means, usually during cell division, first nucleus divides later cytoplasm get separate into two cells and cell wall formed between them ,so that finally two cells formed. But here nucleus keep dividing but immediately cell wall do not formed between each nucleus. Therefore it can not be considered as two cells.

[@Nikhil-wn8mf]

What is archesporium? mam

[@NACBiology]

An archesporium is a group of cells in plants that gives rise to the primary cells involved in spore formation. It serves as the foundational source to spore-producing structures like sporangia or antheridia. For example, in ferns, the archesporium is a group of cells within the sporangium that undergoes division and differentiation to eventually produce spores through meiosis.

[@Hemalatha-e5r8h]

Mam what is mean by sporogenous tissu?

[@NACBiology]

it is a specialized tissue in plants responsible for the formation of spores through the process of sporogenesis. These tissues are found in sporophytes and undergo meiosis to produce haploid spores, which are crucial for sexual reproduction in plants. Examples include sporangia in ferns and anthers in flowering plants.

[@Hemalatha-e5r8h]

Thank you mam

[@PraveenPraveen-ps2ci]

Mam,, out breeding devices can prevent only autogamy,, why not geitenogamy which is genetically a kind of self pollination

[@NACBiology]

Outbreeding devices prevent autogamy (self-pollination within the same flower) but not geitonogamy (transfer of pollen to a different flower on the same plant) because geitonogamy still involves the movement of pollen, even though it's genetically similar to self-pollination. These devices are designed to ensure genetic diversity by encouraging cross-pollination between different plants.

[@PraveenPraveen-ps2ci]

@@NACBiology ok thanks mam

[@kirankumarbise7633]

Mam, is pericarp equal to epicarp..? Or any main difference between epicarp n pericarp

[@NACBiology]

The pericarp and epicarp are related but not the same. Pericarp: This is the entire fruit wall that develops from the ovary wall after fertilization. It consists of three layers: the epicarp, mesocarp, and endocarp. Epicarp: This is the outermost layer of the pericarp. It's the skin or outer covering of the fruit. So, while the epicarp is a part of the pericarp, the pericarp includes all three layers (epicarp, mesocarp, and endocarp).

Mam what is the meaning of tassels. Style r stigma r both mam

[@NACBiology]

In the Maize plant, the silk thread like structure is called tassels. It is nothing but styles. That is a part of female reproductive part of plant. Stigma means the sticky part present at the tip of style. On the stigma, the pollen grains comes and sits.

Mam explain, wind and water pollination 😊

[@NACBiology]

Watch video, I have explained in detail

[@NACBiology]

Wind and water pollination are two methods plants use to transfer pollen for reproduction. In wind pollination, plants like grasses and many trees release lightweight pollen grains that are carried by the wind to reach other flowers. Examples include corn, wheat, and pine trees. In water pollination, plants like water lilies and eelgrass release pollen that floats on the water's surface, eventually reaching other flowers. An example is the water lily, which relies on water currents to transport its pollen to other flowers for fertilization.
