The following points highlight the top eight types of stoma in the epidermis. The types are: 1. Anomocytic 2. Anisocytic 3. Paracytic 4. Diacytic 5. Actinocytic 6. Gramineous 7. Hemiparacytic 8. Hexacytic. Type # 1. Anomocytic (also called ranunculaceous or irregular-celled type): Anomocytic stoma remains surrounded by cells that are not different from other epidermal cells so far as size [...]
In this article we will discuss about the distribution of stomata on leaves. Stomata most frequently occur on regions over the chlorenchymatous mesophyll cells of leaf. Stomata do not occur over the fibre bundles of veins. They also do not occur over the sclerenchyma present on the leaf margins. In majority of monocotyledons where the veins are parallel, e.g. Graminsae, [...]
In this article we will discuss about the stoma in a plant. This will also help you to draw the structure and diagram of stoma in plant. A stoma consists of two guard cells that surround an aperture. In the extinct Devonian Pteridophyte Zosterophyllum myretonianum and Z. ilanoveranum had one guard cell with an aperture in its centre that simulates [...]
