How Do You Spell SUBSIDIARY CELLS?

Pronunciation: [sʌbsˈɪdjəɹɪ sˈɛlz] (IPA)

The word "subsidiary cells" is spelled /səbˈsɪdiəri sɛlz/. The initial syllable "sub-" means "under" and the second syllable "sidiary" comes from the Latin word "sidus" meaning "star", which gives the meaning of "subordinate but still part of the larger system". The final syllable "-ary" indicates that this word is an adjective. The plural form is spelled "cells" instead of "sell", as the first syllable of "subsidiary" is unstressed and pronounced as a schwa /ə/.

SUBSIDIARY CELLS Meaning and Definition

1. Subsidiary cells refer to specialized cells found in certain plants, particularly in the leaves of vascular plants. These cells are typically associated with stomata, which are microscopic pores on the surface of leaves that aid in gas exchange by allowing the intake of carbon dioxide and the release of oxygen and water vapor.

   Within each stoma, there are two crescent-shaped subsidiary cells that flank the opening. These subsidiary cells play a crucial role in regulating the opening and closing of stomata. They are responsible for controlling the turgor pressure of the guard cells, which are two kidney-shaped cells that surround the stomatal pore. By changing their shape and volume, the subsidiary cells influence the movement of water and ions between the guard cells, thereby controlling the opening and closing of the stomata.

   The shape and arrangement of subsidiary cells may vary among different plant species. They can be asymmetric, elongated, or differentiated, depending on the plant's specific needs. For instance, grasses typically have dumbbell-shaped subsidiary cells. This diversity in subsidiary cell morphology suggests their crucial involvement in stomatal regulation.

   Overall, subsidiary cells are an integral part of the complex mechanism that enables plants to regulate gas exchange and water loss through stomata. Their role in maintaining optimal turgor pressure is vital for plant survival, as it ensures an appropriate balance between water conservation and carbon dioxide uptake for photosynthesis.

Etymology of SUBSIDIARY CELLS

The word "subsidiary" originated from the Latin word "subsidium", which means assistance or support. It evolved in the English language to refer to something that is secondary, additional, or supplementary to something else.

In the context of biology, "subsidiary cells" refers to a type of specialized cells that support and assist the main cells or tissues. This term is commonly used in relation to plant biology, specifically in plant leaves, where subsidiary cells are present around stomata (small pores on the leaf surface that facilitate gas exchange). Subsidiary cells surround and provide support to the guard cells, which regulate the opening and closing of the stomata.

Therefore, the etymology of the term "subsidiary cells" combines the Latin root "subsidium", indicating assistance or support, and the biological term "cells", referring to the fundamental unit of living organisms.
