Question

Name algae that reproduce asexually through zoospores. Why are these reproductive units so called?

Answer 1

A zoospore is a motile agamic spore that utilizes a flagellum for motion. Likewise called a multitude spore, these spores are made by certain protists, microscopic organisms, and growths to engender themselves. A zoosporangium is an agamic structure (sporangium) in which the zoospores create in plants, parasites, or protists, (for example, the Oomycota)

Complete answer:
Chlamydomonas multiply asexually through zoospores. They are called zoospores, as they are minuscule motile structures that are commonly found in marine algae. They additionally have flagella for motility. The protoplast contracts and gets isolated from the cell divider. The parent cell loses flagella or in certain types of Chlamydomonas flagella are assimilated. The contractile vacuoles and the neuro-engine mechanical assembly vanish. The cellular material partitions longitudinally by straightforward mitotic division shaping two daughter protoplasts. The second longitudinal division of cellular material happens at the right point to the primary, consequently making four daughter chloroplasts. Some of the time the cellular material may additionally separate to make 8-16-32 daughter protoplasts. The pyrenoids and initials of neuro-engine mechanical assembly additionally partition. The contractile vacuoles additionally create in girl protoplasts. Every little daughter cell creates a cell divider, flagella and changes into zoospore.

Note: Zoospores may have at least one unmistakable sort of flagella: glitter or "enlivened", and whiplash, in different mixes. Tessellated flagella have horizontal fibers known as mastigonemes opposite to the principle pivot which consider more surface zone, and unsettling influence of the medium, giving it the property of a rudder, that is, the motivation behind being utilized for guiding. Whiplash flagella are straight, to control the zoospore through its medium. There is likewise the 'default' zoospore, which just has the impelling, 'whiplash' flagella. Both glitter and whiplash flagella beat in a sinusoidal wave design, yet when both are available.
