Which of the following shows both opposite decussate and opposite superposed phyllotaxy?
1 Psidium
2 Quisqualis
3 Calotropis
4 Ixora
Explanation:
A When successive pair of leaves placed at right angle \(\left(90^{\circ}\right)\) of preceding pair of the leaves and there are four vertical rows Example : - Calotropis, ocimum Opposite superposed - The successive pair of leaves are placed in vertical plane of the preceding pairs of the leaves and there are two vertical rows. Example:- Guava, Jamun (Eugenia jambulina) - In the Guava (Psidium) horizontal branches have superposed and vertical branches shows decussate opposite phyllotaxy.

Circinate vernation is found :
1 Cycas
2 Fern
3 Both (a) and (b)
4 None of these
Explanation:
C Circinate vernation is a type of vernation in which a fern frond is produced. It is tightly curled and it has a tender growing tip. There is a coil in which the growing tip is protected. Circinate refers to leaves or fronds are rolled up with the tip in the centre. These type of vernation is found in Cycas and fern.

The reason for the similar size of vascular bundles in Monocot leaf
1 Modification of epidermal cells
2 mesophyll
3 Bundle sheath
4 Parallel venation
Explanation:
D The main different between monocot and dicot leaf is Parallelvenation found in monocot leaf while Reticulate venation found in dicot leaf Parallel venation may be divergent such as Banana and convergent type like rice, Maize, Sugarcane etc. The parallel venation is main reason for the similar size of vascular bundles in monocot leaf.

Family Fabaceae differs from Solanaceae and Liliaceae. With respect to the stamens, pick out the characteristics specific to family Fabaceae but not found in Solanaceae or Liliaceae.
1 Epiphyllous and Dithecous anthers
2 Diadelphous and Dithecous anthers
3 Polyadelphous and epipetalous stamens
4 Monoadelphous and Monothecous anthers
Explanation:
B Diadelphous when stamens are united Partially and are present in two bunches, they are called diadelphous. Ex Pea. - Diadelphous condition is the characteristics feature of fabaceae family. - Swallen placenta persistent Calyx is the characteristic feature of solanaceae family. - Liliaceae family is a monocot family

Frequency of recombination between gene pairs on same chromosome as a measure of the distance between genes to map their position on chromosome, was used for the first time by
1 Henking
2 Thomas Hunt Morgan
3 Sutton and Boveri
4 Alfred Sturtevant
Explanation:
D Alfred Sturtevant used the frequency of recombination between gene pair on the same chromosome as a measure of the distance between genes and mapped their position on the chromosome. - Alfred Henry Sturtevant was an American geneticist conducted the first genetic map on a chromosome in 1911. He worked with Thomas hunt Morgan on the organism Drosophila melenogaster.
