Consider the following features seen in a plant:

I. Male and female reproductive organs are generally found in separate flowers.

II. The male flowers having a number of long filaments terminating in exposed stamens.

III. The female  flowers having long, feather-like stigmas.

The flowers of this plant would most likely be pollinated by:

1. Wind

2. Water

3. Bees

4. Birds

The only type of pollination that brings genetically different types of pollen grains to the stigma is:

1. Chasmogamy

2. Cleistogamy

3. Geitonogamy

4. Xenogamy

Dioecy in plants prevents:

1. Autogamy but not geitonogamy

2. Geitonogamy but not autogamy

3. Both autogamy and geitonogamy

4. Neither autogamy nor geitonogamy

If the female parent produces unisexual flower:

1. Emasculation must be done before maturity

2. Emasculation must be done after maturity

3. Emasculation must be done before pollination

4. Emasculation is not needed

Genetic self-incompatibility tends to increase

1. pollen dispersal

2. inbreeding

3. pollination

4. outcrossing

If a flower is to be pollinated by moths, it should

(1) be heavily scented

(2) be shaped like a tulip

(3) close about noon

(4) be brightly colored

Female flowers remain submerged in water and the pollen grains are released inside the water in:

1. Sea grasses

2. Vallisneria

3. Water lily

4. Water hyacinth

Which of the following is the most common abiotic pollinating agent?

Which one of the following may require pollinators, but is genetically similar to autogamy?

1. Geitonogamy

2. Xenogamy

3. Apogamy

4. Cleistogamy

Flowers, which have single ovule in the ovary and are packed into inflorescence are usually pollinated by

(1) water

(2) bee

(3) wind

(4) bat
