Quiescent centre is present in part BC. Part A is most suitable for anatomical studies of root.D. Differentialtion of cells can be observed in part C

Answer» Correct Answer - C
Part A is the root hair zone which represents the zone of differentiation or muturation. This is the most suitable part for anatomical studies of root because different types of primary tissues differentiate or mature in this region. Xylem, phloem, pericycle, endodermis, cortex and epiblema are clearly visible in this region.

Define a flower. Name the various parts of a typical flower and describe only non-essential parts.

Answer» Flower. A flower is highly specialized, determinate, reproductive shoot of angiospermous plants (Anthophyta), consisting of an axis (receptacle) on which are inserted four kinds of floral parts.
The major parts of a typical flower are -(i) Non- essential : Calyx and Corolla (ii) Essential : Androecium and Gynoecium
Non-essential parts :
(a) Calyx or whorl of sepals - It is an outermost whorl of sepals. Sepals are usually green, leaf-like and enclose/protect the other floral parts in bud stage. They prevent rapid loss of water from the inner parts of the flower
(b) Corolla or whorl of petals - This is the second whorl of floral )eaves that arise inner to the calyx. Petals are generally conspicuous and brightly coloured. They usually attract the insect pollinators and help in pollination.
Calyx and corolla together constitute the perianth. They are not directly concerned in reproduction and are often referred to as accessory or non-essential floral parts.
