PERISPORE Meaning and
Definition
-
Perispore refers to the outermost layer or covering found on the sporangium or spore case of certain plants, particularly ferns and some mosses. It is a protective structure that surrounds and encloses the spores, providing them with a physical barrier against external influences such as dehydration or mechanical damage.
The perispore is made up of a tough and rigid material that is often resistant to decay. It can have various forms and textures, ranging from smooth and glossy to rough and scaly, and its coloration can vary as well. The characteristics of the perispore are often used as important diagnostic features in identifying and classifying different species of plants.
In ferns, the perispore is formed through the fusion of the outer walls of the spore with an additional layer known as the exospore. The exospore provides extra protection and durability to the spore, facilitating its dispersal and survival in different environments.
The perispore plays a crucial role in the reproductive cycle of these plants. As the sporangium matures, it releases the spores, which are then dispersed into the surrounding environment. The perispore helps to shield the spores from unfavorable conditions until they find a suitable location to germinate and develop into new individuals.
