The ovule of an angiosperm is technically equivalent to
The ovule of an angiosperm is technically equivalent to a megasporangium, which is the structure that produces megaspores through meiosis. The megaspore further develops into the female gametophyte, while the ovule develops into the seed after fertilization.
Which one of the following may require pollinators, but is genetically similar to autogamy?
Geitonogamy is functionally cross pollination but genetically it is autogamy because in geitonogamy the pollens come from the same plant.
Flowers, which have single ovule in the ovary and are packed into inflorescence are usually pollinated by
The flowers with packed inflorescence and single ovary are air pollinated. These flower have pollen grains produced in large numbers, which are light weighted, sometimes winged, e.g. cereals and grasses.
Functional megaspore in an angiosperm develops into
In angiosperms, functional megaspore develops into an embryo sac. The functional megaspore is the first cell of female gametophyte.
