Meaning of endotheca
endotheca (n.)
The tissue which partially fills the interior of the interseptal chambers of most madreporarian corals. It usually consists of a series of oblique tranverse septa, one above another.
endotheca Sentence Examples
- Endotheca refers to the innermost layer of an anther in a flower, responsible for producing pollen grains.
- The endotheca, derived from the middle layer of the anther, comprises specialized cells that contribute to pollen development.
- The endotheca, along with the tapetum, provides nutrients and promotes the maturation of pollen grains within the anther.
- The endotheca is a dynamic tissue that undergoes cellular changes during anther development, transitioning from a meristematic state to a differentiated state.
- The endotheca plays a role in the formation of the pollen wall, including the exine and intine layers, which contribute to pollen viability and dispersal.
- The endotheca contains specific proteins and enzymes involved in the synthesis and deposition of the pollen wall components, ensuring the proper development and functionality of pollen grains.
- In some plant species, the endotheca undergoes programmed cell death, leading to the release of mature pollen grains from the anther, a process known as anther dehiscence.
- The endotheca can serve as a source of genetic material for studying pollen development and the molecular mechanisms underlying pollen production.
- Abnormalities in the endotheca, such as defects in cell division or differentiation, can lead to pollen sterility and impact plant reproductive success.
- The study of the endotheca is relevant in understanding plant reproductive biology, pollen-mediated pollination processes, and the genetic basis of pollen development.
