What is the point of attachment of Funicle to the body of ovule called?
hilumThe hilum is the point of attachment of funicle with the chalazal end.
It is the point where ovule attaches to the base.
It is generally present as an eye of the seed as it is present as a scar.
How satisfied are you with the answer?.
What is called Micropyle?
Micropyle may refer to: Micropyle (botany) a minute opening in the integument of an ovule of a seed plant. Micropyle (zoology), a differentiated area of surface in an egg, through which a sperm enters.
Where is Micropyle found?
Microplye is a ‘small opening’ in the ovule of the seed plant, and also it is ‘small opening’ in the surface of egg by which the sperm enters. EXPLANATION: Micropyle is used for the various functions and processes of the egg or the seed plant. It is located at top of the seed or egg.
What is the function of Antipodals?
Antipodals are nutritive in function; it nourishes the embryo sac. Substances produced by the antipodals helps in the growth and development of the endosperm. It contains large amount of starch, lipids and proteins which are used up by the developing embryo and the endosperm.
What is the function of stigma?
Stigma is the topmost part of carpels in the gynoecium of a flower. In all flowering plants, stigma functions as a receptive tip, which collects pollen grains.
Are Synergids haploid?
The lower end of the embryo sac consists of the haploid egg cell positioned in the middle of two other haploid cells, called synergids. The synergids function in the attraction and guidance of the pollen tube to the megagametophyte through the micropyle.
What is Micropyle function?
Functions of micropyle: (i) When soaked in water, the seeds absorb water mainly through the micropyle and make it available to the embryo for germination.
What is a Funicle?
botany the stalk that attaches an ovule or seed to the wall of the ovaryAlso called: funiculus.
Is ovule the same as egg?
Oocyte: the cell in animals that develops into an egg. Once it is fertilizable, it is referred to as an egg. Ovule: the structure in seed plants that develops into a seed after fertilization. It consists of one or two integuments forming its outer layers, the nucellus and the female gametophyte.
What are the functions of Synergids?
The synergid cells direct pollen tube growth toward the female gametophyte, and facilitate the entrance of the tube into the embryo sac. Once the pollen tube enters the synergid cell, its growth is arrested, the tip of the tube breaks, and two sperm cells are released.
What is the main function of cotyledons?
The cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food reserves of the seed. As these reserves are used up, the cotyledons may turn green and begin photosynthesis, or may wither as the first true leaves take over food production for the seedling.
