Grafting is not possible in monocotyledons because they lack cambium as it helps in binding the two parts of the stem.

The correct way of sowing leaf and stem cuttings of a plant is vertically with morphological apical end upwards.

Banana has lost its ability to produce seeds.At present, modern edible bananas have undergone certain processes of special selection and have lost their ability to produce seeds.

The union of two gametes of same sex is called parthenogamy.

Apomixis does not involve gametic union. Apomixis in flowering plants is defined as the asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization, leading to embryo development.

Sweet potato and dahlia are the plants which propagate vegetatively by roots of the plants. Vegetative propagation is a method of asexual reproduction.

For self–pollination, a flower should be bisexual.For example:-Sunflower, hibiscus, mustard, rose, lily.

Pollination by water is called hydrophily.It can occur in one of two ways. Either the pollen grains themselves are carried on or under the surface of the water, or the male flowers break off and float along until they come into contact with a female flower.

Pollination through insects is called entomophily. Several insects are reported to be responsible for the pollination (potential or effective) of many plant species, particularly bees, Lepidoptera (butterflies and moths), wasps, flies, ants and beetles.

The pollination performed by bats is called chiropterophily.Bat pollination is most common in tropical and desert areas that have many night-blooming plants.
