What is the function of cystocarp?
A cystocarp is the fruiting structure produced in the red algae after fertilization, especially such a structure having a special protective envelope (as in Polysiphonia). The structure from which carpospores are released.
What is the cystocarp attached to?
gametophyte
The zygote grows, still attached to the gametophyte, within a structure called the cystocarp. The cystocarp has an external layer called the pericarp that is formed from the female gametophyte’s tissue (meaning it is haploid).
Which are the carpospores located in Batrachospermum?
The gonimoblast branches out, and the terminal cells of such branched gonimoblast grow into carposporangia. Each carposporangium generates a unique single haploid carpospore that is rounded. The cystocarp or carposporophyte is a structure of gonimoblast filaments, carposporangia, and carpospores.
What is the Colour of Batrachospermum?
Batrachospermum, genus of freshwater red algae (family Batrachospermaceae) ranging in colour from violet to blue-green. The long, branched, threadlike filaments bear dense whorls of branchlets, resembling beads on a string.
Is Batrachospermum unicellular?
They are unicellular and free swimming, and they are subsequently found in the phy-toplankton. Species can also be found in wetlands and ponds.
What are Carpogonia give example?
: the egg-bearing portion of the female reproductive organ in some red algae.
What is the habitat of Batrachospermum?
Habitat: Batrachospermum can be found in cold lakes, streams, and bogs around the world (Graham and Wilcox 2000). Widespread in North America is B. gelatinosum, as far north as the tundra.
Where is Batrachospermum found?
Note: Batrachospermum is commonly found in shaded areas of reservoirs containing freshwater. They do not live in water that is exposed to more light. It lives in cold water that has a high amount of organic materials. They are the generalists of the red algae that have adapted themselves to the freshwater habitat.
Why is Batrachospermum in red algae?
Red algae are abundant in marine habitats, but are relatively rare in freshwaters, where they are usually found in lotic habitats. For example, Batrachospermum (Fig. 9.5C) is a red alga found in streams and springs throughout the world. The algae are red because of their phycoerythrins, which impart a red hue.
What is the meaning of Batrachospermum?
Definition of Batrachospermum : a genus (the type of the family Batrachospermaceae) of red algae of the order Nemalionales found in slow-moving fresh waters and having a thallus that consists of a conspicuous central axis bearing transverse whorls of short branches at regular intervals.
