What is Plurilocular sporangia in botany?
What are Plurilocular Sporangia. Plurilocular sporangia are the other type of sporangia produced by the brown algae, Ectocarpus. Plurilocular sporangia also develop from the terminal cells of the branchlets. These are spherically elongated structures. A row of 5-12 cells is produced in the plurilocular sporangium.
What are unilocular and Plurilocular sporangia?
Unilocular Sporangia vs Plurilocular Sporangia Unilocular sporangia consist of a single enlarged cell which results in the formation of haploid spores. Plurilocular sporangia consist of many cuboidal shaped cells which give rise to many diploid zoospores.
What is difference between Plurilocular sporangia and Plurilocular gametangia?
The plurilocular gametangia develop from the terminal cell of a lateral branchlet while plurilocular sporangia have no reduction division& they also germinate into sporophytes bearing unilocular or neutaral sporangia.
Is the class of Ectocarpus?
Brown algae
Ectocarpus/Class
Are Antheridia gametangia and sporangia?
Male gametangia are referred as antheridia. Antheridia produce sperms and release to outside for syngamy. Gametangia are found in the gametophytic generation.
What is the life cycle of Ectocarpus?
Like many brown algae, Ectocarpus has a haploid–diploid life cycle that involves alternation between two multicellular generations, the sporophyte and the gametophyte (Fig.
Which plant is Moss?
Moss, (division Bryophyta), any of at least 12,000 species of small nonvascular spore-bearing land plants. Mosses are distributed throughout the world except in salt water and are commonly found in moist shady locations. They are best known for those species that carpet woodland and forest floors.
Which plant is called as moss plant?
Dawsonia, the tallest moss in the world, can grow to 50 cm (20 in) in height. There are approximately 12,000 species. Mosses are commonly confused with liverworts, hornworts and lichens….Moss.

Where is Oedogonium found?
Oedogonium, genus of filamentous green algae (family Oedogoniaceae), commonly found in quiet bodies of fresh water. They often are attached to other plants or exist as a free-floating mass. Oedogonium filaments are typically unbranched and only one cell thick.
How many zoospores are produced in the unilocular sporangia?
The meiotic cell division of the unilocular sporangia is followed by a series of mitotic cell divisions and produce 32-64 zoospores. These zoospores are haploid.
Which is the type of sporangia produced by Ectocarpus?
Unilocular sporangia are a type of sporangia produced by a brown algae, Ectocarpus. Unilocular sporangia consist of an enlarged, single cell, which undergoes meiosis to produce haploid zoospores. The unilocular sporangia develop from the terminal cells of the small branchlets.
What kind of jobs are available in botany?
With these, positions are available as laboratory technicians or technical assistants in education, industry, government, museums, parks and botanical gardens. As in other fields, a wider range of positions is available with more education and experience.
Where can I get a job as a plant biologist?
The major employers of plant biologists are educational institutions, federal and state agencies, and industries. Job opportunities usually depend upon educational training and experience. New positions in botany are expected to increase at an above-average rate through the turn of the century.
