How many microsporangia are located at the corners of a typical bilobed anther of angiosperm?
1 2
2 4
3 8
4 1
Explanation:
Four microsporangia are located at the corners of a typical bilobed anther of angiosperm. Microsporangium is a sporangial structures which produces spores. Anther of angiosperms shows two anther lobes. Each anther lobes develops into two microsporangium. Hence anther has four pollen sacs at four corners of it. Struemuro of stamen

Vivipary is a peculiar characteristic of
1 Mesophytes
2 Xerophytes
3 Mangrooves
4 Emergent hydrophytes
Explanation:
Adaptation of vivipary has mostly occured in some halophytes. Vivipary plants grow in highly saline area. Mangrooves plant of high salt tolerent grows in water of high salinity. - Mesophytes are plants that require a moderate amount of water.

In angiosperms, the endosperm is classified on the basis of which one of the following criteria?
1 Development
2 Position
3 Ploidy
4 Function
Explanation:
In angiosperms, the endosperm is classified on the basis of development. Angiosperms have three types of endosperms which are categorized based on the timing of cell wall production by plant species. The nuclear, cellular \& helobial endosperms are among them. - Endosperm is present in the seeds of most of the angiosperms. It provides nourishment to the growing embryo. - Ploidy level of endosperm in angiosperm is generally triploid or $3 \mathrm{n}$.

Which one of the following pairs gives rise to fruit and seed, respectively, in a typical angiosperm plant?
1 Ovule and ovary
2 Ovary and pollen
3 Pollen and anther
4 Ovary and ovule
Explanation:
The fertilization in plants brings about various changes in the structure of a flower. In the majority of the cases, withdraw all the parts of the flower i.e. calyx, carolla and androecium except the ovary which remain on the thalamus. The ovary grows and eventually transforms into the fruit that contains the seeds. A fertilized mature ovary is what is known as a fruit. - After fertilization, the megasporangium or ovule becomes the seed.

Which of the following cell-type is not dead at maturity in angiosperms ?
1 Sieve tube elements
2 Phloem fibres
3 Vessels
4 Xylem fibres
Explanation:
In plant anatomy, sieve tube elements also called sieve tube members are highly specialized type of elongated cell in the phloem tissue of flowering plants unlike the water - conducting xylem vessel elements that are dead when mature sieve elements are living cells. Phloem fibres are generally absent in the primary phloem but are found in the secondary phloem and hemp are made of dead sclerenchymatous cells.
