0 Irregular flower are those in which some of the floral leaves in any one series have a different shape from the other for example, the petals of pea or violet. They have only one plane of symmetry. These flowers are bilaterally symmetrical i.e - they are divisible into equal halves about one plane only. The irregular flower is also called the zygomorphic flower.

When gynoecium is present in the topmost position of thalamus, the flower is known as :
1 Inferior
2 Epigynous
3 Perigynous
4 Hypogynous
Explanation:
D The gynoecium is situated at the top of the thalamus. If upper part of thalamus is slightly swollen and forms a cushion like a disc. Thalamlus is basically the receptacle found in angiosperms. Ex- Hibiscus rosa sinensis, ranunculus, Brassica, Brinjal etc.

The smallest flower is that of the :
1 Onion
2 Mustard
3 Fig
4 Wolffia microscopia
Explanation:
D Wolffia species are the smallest flowering plants on earth with \(2 \mathrm{~mm}\) measurements. They are commonly called as watermeal or duckweed. Wolffia species are free floating plants without roots. The flower has one stamen and one pistil. Rafflesia is largest flower with the measurement of 60 \(\mathrm{cm}\) to \(80 \mathrm{~cm}\).

The order of opening of flower parts from the periphery towards the centre is called
1 acropetal
2 centripetal
3 centrifugal
4 basipetal
Explanation:
B In general the order of opening of floral parts from the periphery towards the center is called centripetal, while from centre towards the periphery is called centrifugal. - Acropetal order is a flower arrangement in which the new flowers are at the top, and the older flowers are at the bottom. - Basipetal The arrangement of older flowers at the apex and fresh flowers and buds at the base is known as basipetal flower.

Opening of floral buds into flowers is a type of
1 autonomic movement of locomotion
2 autonomic movement of variation
3 paratonic movement of growth
4 autonomic movement of growth
Explanation:
D Opening of floral buds into flower is a type of autonomic movement of growth (Nastic movement). This is a non directional movement in which the response is determined by the structure of the responsive organ and not to the direction of stimulus. Greater growth on one side causes the organ to bend to the opposite side.
