Morphology of Flowering Plants

An aggregate fruit is one which develops from

1. multicarpellary syncarpous gynoecium
2. multicarpellary apocarpous gynoecium
3. complete inflorescence
4. multicarpellary superior ovary.

Among bitter gourd, mustard, brinjal, pumpkin, china rose, lupin, cucumber, sunhemp, gram, guava, bean, chilli, plum, petunia, tomato, rose, Withania, potato, onion, aloe and tulip how many plants have hypogynous flower?

1. Fifteen
2. Eighteen
3. Six
4. Ten

In China rose the flowers are

1. zygomorphic, hypogynous with imbricate aestivation
2. zygomorphic, epigynous with twisted aestivation
3. actinomorphic, hypogynous with twisted aestivation
4. actinomorphic, epigynous with valvate aestivation

Seed coat is not thin, membranous in

1. groundnut
2. gram
3. maize
4. coconut.

Among flowers of Calotropis, tulip, Sesbania, Asparagus, Colchicum, sweet pea, Petunia, Indigofera, mustard, soybean, tobacco and groundnut, how many plants have corolla with valvate aestivation?

1. Six
2. Seven
3. Eight

2. tulip
3. aloe
4. soybean.

In a cymose inflorescence the main axis

1. has unlimited growth
2. bears a solitary flower
3. has unlimited growth but lateral branches end in flowers
4. terminates in a flower.

1. Pea : C3 pathway, endospermic seed, vexillary aestivation
2. Tomato : twisted aestivation, axile placentation, berry
3. Onion : bulb, imbricate aestivation, axile placentation
4. Maize : C3 pathway, closed vascular bundles, scutellum
