(10) A flower with both androecium and gynoecium is called ______________ .

(1) The floral whorls in a flower are seated on the anther.

(2) Flower is the reproductive part of a plant

(3) Vallisneria is generally wind pollinated.

(4) Water enters the seeds through micropyle.

(5) An example of a monocot seed is maize.

(6) Oxygen is not necessary for seed germination.

(7) In fleshy fruits the endocarp is always soft and fleshy.

(8) Endosperm provides food to the developing seedling.
