(a) The sulphur is needed by young leaves, stem and root tips. If it is not available, these parts would show the deficiency symptoms which include
(i) reduced growth
(ii) extensive root growth
(iii) hard and woody stem
(iv) chlorosis of young leaves.
The immobile elements are transported in plant upto the tip level, so their deficiency appear first at the tips of growing apices of roots and shoot.

The basis of observation and way to test the hypothesis for the insertion of β-galactosidase lacking its own transcription control inserted in a cluster of piRNA genes inhibits normal expression of gene elsewhere in the genome and when inserted outside the piRNA gene cluster, the normal gene is expressed properly. Concept introduction: Piwi-interacting RNA or piRNA is a class of RNA that contains small non-coding sequences expressed in animal cells. They interact with piwi proteins and are involved in regulating the transposons and also regulate genetic elements during spermatogenesis. β-galactosidase cleaves β-galactosides to individual galactose monosaccharides.

Compound Epithelium It consists of more than one layer of cells. Only the cells of the deepest layer rest on the basement membrane. Being multilayered, compound epithelia have little role in secretion or absorption, but they provide protection to underlying tissues against mechanical, chemical, thermal or osmotic stresses. Compound epithelia may be stratified or transitional. (i) Stratified Epithelium has many layers of epithelial cells. The deepest layer, stratum germinativum, is formed by columnar or cuboidal cellis. But the morphology of the supericial layers varies in the different kinds of stratified epithelia. In stratified cuboidal epithelium, the superficial cells are cuboidal. It lines the inner surfaces of larger salivary and pancreatic ducts. Stratified non-keratinised squamous epithelium
