Question:

Find out the False statement from below ones: I. Calyx and corolla are reproductive organs of a flower. II. Zygomorphic flower can be divided into two equal radial halves in any radial plane. III. Flowers without bracts are termed as bracteate. IV. Parthenocarpic fruit is formed after fertilization of the ovary. V. In legumes seed is non-endospermic. VI. Ovary is inferior in Fabaceae. VII. A fertile stamen is called staminode. VIII. Radical buds develop on roots.

Options:

1. I, II, III, IV, VI, VII
2. I, II, V, VIII
3. III, IV, VIII
4. IV, V, VIII

Solution:

1. Calyx and corolla are accessory organs, while androecium and gynoecium are reproductive organs. 2. When a flower can be divided into two similar halves only in one particular vertical plane, it is zygomorphic, e.g., pea, gulmohur, bean, Cassia. 3. Flowers with bracts, reduced leaf found at the base of the pedicel, are called bracteate and those without bracts, ebracteate. 4. If a fruit is formed without fertilisation of the ovary, it is called a parthenocarpic fruit. 5. Ovary is superior in Fabaceae. 6. A sterile stamen is called staminode.
