RECENT APPROACH TO VIEW STOMATAL ANATOMY UNDER FOLDSCOPE

DEFINITION

  • Stomata are minute pores or holes which occur in the epidermis of the plants.
  • Each stoma remains surrounded by two kidneys or bean shaped epidermal cells the guard cells.

Here, with the help of Foldscope some of the beautiful stomata are differentiated with specific strains in Dicotyledons plants. They are as follows:

TYPES OF STOMATA

  1. For Diacytic stomatal differentiation, we have used Adathoda vasica
  2. Paracytic stomatal differentiation, we have used Ixora coccinea

 1. Diacytic stomata in Adathoda vasica Nees.

This beautiful picture shows the Diacytic stomata
  • This medicinal plant belongs to the family Acanthaceae.
  • The stomata were stained with the help of Toluidine blue

  • Diacytic stomata are also called Cross-celled
  • Diacytic – Stoma enclosed by a pair of subsidiary cells whose right angle to guard cells.

2. Paracytic stomata in Ixora coccinea L.

  • The second type Paracytic stomata is seen in Ixora coccinea belongs to the family Rubiaceae.

  • Paracytic stomata are also called Parallel celled In this type, the stoma accompanied by one or more subsidiary cells which lies parallel to the pore and guard cells.
