Description : The special modified epidermal cells surrounding stomatal pore are called (1) Epithelial cells (2) Guard cells (3) Subsidiary cells (4) Accessory cells
Last Answer : Guard cells
Description : The cells which are closely associated and interacting with guard cells are - (1) Transfusion tissue (2) Complementary cells (3) Subsidiary cells (4) Hypodermal cells
Last Answer : (3) Subsidiary cells Explanation: Guard cells interact physiologically and mechanically with subsidiary cells.

Last Answer : Whent the subsidiary or neighboring cells have a common origin with the guard cells such type of stomata ontogeny is called as – Mesogenous development
Description : Which of the following statements is not true for stomatal apparatus? (a) Guard cells invariably possess chloroplasts and mitochondria. (b) Guard cells are always surrounded by subsidiary cells. (c) Stomata are involved in gaseous exchange. (d) Inner wall of guard cells are thick

Description : Which epidermal cells are also called prickle cells? -Biology
Last Answer : Stratum spinosum, 8-10 cell layers, also known as the prickle cell layer contains irregular, polyhedral cells with cytoplasmic processes, sometimes called “spines”, that extend outward and contact neighboring cells by desmosomes. Dendritic cells can be found in this layer.
