WHAT DOES THECA MEAN IN ENGLISH?

Theca

A theca refers to any case, covering, or sheath. In botany, the theca of an angiosperm consists of a pair of microsporangia that are adjacent to each other and share a common area of dehiscence called the stomium. Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament. An anther and its filament together form a typical stamen, part of the male floral organ. The typical anther is bilocular, i.e. it consists of two thecae. Each theca contains two microsporangia, also known as pollen sacs. The microsporangia produce the microspores, which for seed plants are known as pollen grains. If the pollen sacs are not adjacent, or if they open separately, then no thecae are formed. In Lauraceae, for example, the pollen sacs are spaced apart and open independently. The tissue between the locules and the cells is called the connective and the parenchyma. Both pollen sacs are separated by the stomium. When the anther is dehiscing, it opens at the stomium. The outer cells of the theca form the epidermis. Below the epidermis, the somatic cells form the tapetum.

Definition of theca in the English dictionary

The definition of theca in the dictionary is an enclosing organ, cell, or spore case, esp the capsule of a moss. Other definition of theca is a hard outer covering, such as the cup-shaped container of a coral polyp.
