Q.1
In which one of the following, the male and female gametophytes don’t have free-living independent existence?
0%
a) Pteris
0%
b) Funaria
0%
c) Polytrichum
0%
d) Cedrus
Explanation
Pteris reproduces by means of spores. Pteris is a homosporous fern. The sorus of Pteris is called coenosorus Homosporous: producing spores of one kind only, which develop into hermaphrodite gametophytes. Hermaphroditism, the condition of having both male and female reproductive organs. Cedrus is a gymnosperms, In gymnosperms, a leafy green sporophyte generates cones containing male and female gametophytes; female cones are bigger than male cones and are located higher up in the tree. A male cone contains microsporophylls where male gametophytes ( pollen ) are produced and are later carried by wind to female gametophytes. Funaria and Polytrichum is Bryophytes, Bryophytes have neither pollen nor flowers and rely on water to carry the male gametes (the sperm) to the female gametes (the eggs). Answer:(a)

The characteristic which Linnaeus considered for classification of plants:
0%
a) Gynoecium structure.
0%
b) Androecium structure.
0%

Androecium is an essential whorl which consists of the stamens or the male reproductive part of a flower. Stamen consists of slender stalk like structure called a filament. It consists of an anther which has pollen grains. The classification system of Linnaeus was based on floral characteristics. He chiefly used characters of stamen’s. Therefore, his system is called sexual system Answer:(b)
