Choose the incorrect amongst the following.
1 Hypostomatic – Stomata are present more on lower epidermis than on upper epidermis.
2 Epistomatic – Stomata are present more on upper epidermis than on lower epidermis.
3 Amphistomatic – Stomata are non-functional or absent.
4 Sunken stomata – Stomata are deep seated back the surface.
Explanation:
(c)In dicot leaves, stomata are generally present on lower epidermis (hypostomatic)whereas in monocot leaves, they are present on both the surfaces (amphistomatic). In free floating hydrophytes, stomata are restricted to upper epidermis (epistomatic)where as in submersed hydrophytes, stomata are either non-functional or absent. In algae stomata are sunken (deep sealed)in case of xerophytes.
