The phycoplast is a microtubule structure observed during cytokinesis in members of the Chlorophytina, the largest and most well known subphylum of chlorophyte green algae. Cytokinesis in green algae occurs via a diverse range of mechanisms, including cleavage furrows in some algae and cell plates in others.
Towards the right: Phragmoplast enlarges in a donut-shape towards the outside of the cell, leaving behind mature cell plate in the center. The cell plate will transform into the new cell wall once cytokinesis is complete. The phragmoplast is a plant cell specific structure that forms during late cytokinesis.
Phycology (from Ancient Greek φῦκος (phûkos) 'seaweed' and -λογία 'study of') is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms
Mougeotia is a genus of filamentous charophyte green algae of the order Zygnematales. It is a common component of freshwater aquatic habitats around the world. [ 2 ] Described in 1824 by Carl Adolph Agardh , [ 1 ] its name honors the French botanist Jean-Baptiste Mougeot .
Pediastrum possesses a haplontic life cycle, and can be divided into three types. [12] The most commonly seen is the first kind of asexual life cycle (ALC1), which generates autocolonies. In ALC1 the zoospores aggregate into an orderly flat disk, with concentric rings (central cell, six cells, and then nine cells.)
Along with red algae [1] and cyanobacteria, they harvest light via phycobilisomes, structures consisting largely of phycobiliproteins. The green algae and land plants have lost that pigment. [11] Like red algae, and in contrast to green algae and plants, glaucophytes store fixed carbon in the cytosol. [12]
Most algae have dominant gametophyte generations, but in some species the gametophytes and sporophytes are morphologically similar . An independent sporophyte is the dominant form in all clubmosses , horsetails , ferns , gymnosperms, and angiosperms that have survived to the present day.
Batrachospermum is a genus of red algae from the family Batrachospermaceae.Due to its complex biological life cycle, descriptions of the taxon typically focus on gametophytes, while sporophytes, i.e., carposporophytes, are filamentous structures growing on the gametophyte, on which they depend.
