Definition of fucoid in English: fucoidnoun ˈfjuːkɔɪdˈfyo͞okoid Botany A brown seaweed or fossil plant of a group to which bladderwrack belongs. Order Fucales, class Phaeophyceae, including genus Fucus Example sentencesExamples - They found, however, no difference in attachment strength between Fucus evanescens and the native fucoids when plants of the same size were compared.
- However, since F. evanescens did not exclude other fucoids in its new range, its effect on the recipient biota is probably small.
- This suggests a rapid, recent evolution of at least northern hemisphere temperate fucoids.
- It is well known that most fucoids are prevented from establishing on exposed shores by limpet grazing.
- Without grazers to remove them, the faster growing epiphytes could outcompete fucoids by covering all surfaces or at least covering enough surface area to decrease photosynthetic activity of Fucus.
adjective ˈfjuːkɔɪdˈfyo͞okoid Botany Relating to or resembling a brown seaweed, especially a fucoid. Example sentencesExamples - The zygotes of the fucoid brown algae have long been studied by developmental biologists in an effort to understand how cellular polarity arises.
- Ceratopteris spores, like fucoid zygotes, divide unequally to produce a small rhizoid cell and a larger cell that develops into the thallus.
- It was covered in fucoid algae and delicate yellow and orange plumose anemones that drew us in closer, as there were often a few gems nestling in them.
- In the fucoid zygote, polarization events can be triggered by a range of stimuli, including unidirectional light and fertilization.
