In dicotyledon the vascular bundles are usually more or less in a ring and show different arrangements at the nodes and internodes. The vascular cylinders are generally continuous at the internode and their continuity is interrupted at the nodal region due to the emergence of bundles that terminate either at the leaf bases, axillary buds or stipules etc. At the [...]
In this article we will discuss about the occurrence and position of stomata in epidermis. Stoma occurs in the epidermises of any of the aerial parts of plants. It occurs in Bryophytes, Pteridophytes and Spermatophytes. In Bryophyta stoma is found on the capsules of Anthocerotopsida and Bryopsida. In Marcnantiopsida stomata are absent; instead pores are present on the surface of [...]
The upcoming discussion will update you about the difference between dicotyledonous stem and monocotyledonous stem. Difference # Dicotyledonous Stem: 1. Internally it is differentiated into epidermis, cortex and stele. 2. Epidermis it bears hairs that are usually multicellular. 3. Cortex the peripheral layers, i.e. hypodermis are generally collenchymatous. 4. The rest of cortex bears nonvascular tissues. 5. The innermost layer [...]
