What is Oedogonium Macrandrous?

What is Oedogonium Macrandrous?

Sexual reproduction in Oedogonium is oogamous; and can be monoecious or dioecious. Species may either be macrandrous (lacking dwarf males) or nannandrous (possessing dwarf males). Dwarf males are small, short, antheridium-producing filaments attached near the oogonia (female sex organ).

What is Macrandrous and Nannandrous species of Oedogonium?

As adjectives the difference between macrandrous and nannandrous. is that macrandrous is (botany) having antheridia formed on normal-sized male vegetative filaments while nannandrous is having nannandria.

What is the name of basal cell of Oedogonium?

Out of about 400 species more than 200 have been reported from India. They are very common in pools, ponds, lakes etc. The filamentous plant body may get attached with the stone, wood, leaves of aquatic plants, small branches of dead plant remain in water etc. by their basal cell the holdfast.

What is Nannandrous Oedogonium?

[na′nan·drəs] (botany) Pertaining to species of plants in which male members are markedly smaller than females, such as in some algal species of Oedogonium that have antheridia produced in special dwarf filaments.

How is Oedogonium unique?

We know that when a cell divides into two daughter cells, two separate processes are involved, one is cell division and the other is cell elongation including the cell walls. The method of cell division and growth of cell wall is unique and peculiar in Oedogonium. The cell wall does not elongate in the usual way.

How do you identify Oedogonium?

Isolates of Oedogonium were identified using DNA barcoding and taxonomic keys. Samples of each isolate were examined under dissecting and compound light microscopes and their morphological characteristics were recorded. Where possible, each sample was identified to species using taxonomic keys [15].

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.

What’s the meaning of phycology?

science of algae
: the study or science of algae. — called also algology.

Who is the father of phycology?

Wilhelm Wundt is the man most commonly identified as the father of psychology.

What is the meaning of Bryologist?

Bryology (from Greek bryon, a moss, a liverwort) is the branch of botany concerned with the scientific study of bryophytes (mosses, liverworts, and hornworts). Bryologists are people who have an active interest in observing, recording, classifying or researching bryophytes.

Who is the father of Indian phycology?

Narendra Nath Sen Gupta (23 December 1889 – 13 June 1944) was a Harvard-educated Indian psychologist, philosopher, and professor, who is generally recognized as the founder of modern psychology in India along with Indian Scientist Gunamudian David Boaz.

How are the cells of the Oedogonium differentiated?

The filaments are unbranched and cells of each filament are attached end to end and form uniseriate row (Fig. 3.72A). The filament is differentiated into 3 types of cells: 1. Basal cell, 2. Apical cell and 3. Middle cells. 1. Basal Cell: It is the lowermost cell of the fila­ment.

What are the two types of Oedogonium plants?

Based on the size of male filament the plants are divided into two groups: Macrandrous and Nannandrous type. 11. In macrandrous type the antheridia develop into the filament of normal size.

Where are the antheridia and oogonia found in a macrandous monoecious?

In macrandous monoecious species, the antheridia and oogonia are always found on the same filament. In contrary, in macrandous dioecious species, the antheridia and oogonia are produced on different filaments. Although filaments bearing antheridia and oogonia are morphologically similar, they differ physiologically.

How are sexual organs produced in an Oedogonium?

The sexual organs, antheridia and oogonia, may be produced on the filaments of normal size (macrandrous species), or the oogonia are borne on normal filament, the antheridia being produced on special dwarf male fi­lament or nannandrium (nannandrous species) consisting of a few cells. Macrandrous species may be homothallic or heterothallic.

What is Oedogonium Macrandrous? Sexual reproduction in Oedogonium is oogamous; and can be monoecious or dioecious. Species may either be macrandrous (lacking dwarf males) or nannandrous (possessing dwarf males).
