TROPHOZOOID Meaning and
Definition
-
Trophozooid, noun:
A trophozooid is a single, motile, feeding stage or individual in the life cycle of certain organisms, particularly in colonial or multicellular groups such as cnidarians or sponges. It refers to the active form of an organism that performs essential functions such as feeding, digestion, and reproduction. Trophozooids are generally responsible for obtaining and processing nutrients.
In cnidarians (e.g. jellyfish, sea anemones), the trophozooid is a specialized polyp that captures prey using stinging cells called nematocysts. These trophozooids possess tentacles arranged around the oral cavity, which help in capturing and consuming prey, as well as digesting them into suitable forms for absorption. The trophozooids are usually connected to other polyps in the colony, often sharing a common digestive system.
In sponges (phylum Porifera), the trophozooid is a flagellated cell that actively moves within the sponge body wall. These cells have flagella, which generate water currents to facilitate filter-feeding by capturing and absorbing small organic particles, such as bacteria or plankton.
Overall, trophozooids represent the active, nourishing, and reproductive members within colonial or multicellular organisms. They contribute essential functionalities to the life cycle of these organisms, ensuring the acquisition and processing of nutrients necessary for growth, development, and survival.
