Oedogonium/Kingdom
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 from Zoosporangium during asexual reproduction in Oedogonium?
Asexual Reproduction of Oedogonium: 2. Zoospores are formed in the cap cells singly, when the cell starts to function as zoosporangium.
What is the life cycle of Oedogonium?
The life cycle of Oedogonium is haplontic. The egg from the oogonia and the sperm from the antheridia fuse and form a zygote which is diploid (2n). The zygote then undergoes meiosis and reproduces asexually to form the filamentous green alga which is haploid (1n).
What are the characteristics of Oedogonium?
Important Features of Oedogonium:
- This is a common fresh water alga growing on substratum like sand particles, rocks etc.
- The plant body is unbranched, filamentous and differentiated into apex and base.
- Cells have reticulate chloroplasts.
- Presence of caps on the young dividing cells.
What is Nannandrous Oedogonium?
: having oogonia borne on normal-sized plants and antheridia borne on greatly reduced plants or filaments —used of green algae of the family Oedogoniaceae — compare macrandrous.
What are CAP cells in Oedogonium?
Cap cells are found in algae oedogonium. In filaments of algae order oedogoniales, towards the upper end of some cells a ring like structure is present called cap or apical cap.
What is the difference between Macrandrous and Nannandrous?
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.
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 Oedogonium Foveolatum move?
Oedogonium. Oedogonium reproduces asexually by fragmentation and by producing large, wallless zoospores with an eyespot, contractile vacuoles, and a ring of flagella. The motile zoospores are released from the parent cells and move to a suitable substrate. contain small sperm with multiple flagella.
What is the cap cell?
A cell, seen in filaments of algae in the order Oedogoniales, that has one to several ‘caps’ of cell wall material at its anterior end. These result from a distinctive form of cell division that involves the formation of rings of new cell wall material prior to nuclear division.
Where are cap cells found?
Cap cell is found in the peripheral nervous system.
What is Nannandrous?
[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.
Where can you find Oedogonium in a pond?
Oedogonium occurs as the fresh water filamentous alga found in ditches, ponds, pools and lakes. It occurs as epiphytic alga found attached on leaves and twigs of other plants. It is also found attached on other algae such as Cladophora.
How are zoospores formed in an Oedogonium?
The zoospores are multiflagellate and ovoid, pyriform or spherical in shape. They are uninucleate with single chloroplast and occasionally with an eye-spot. During favourable condition, the zoospore formation begins in a cap cell of the filament.
What kind of alga is Oedogonium attached to?
Class – Chlorophyceae. Order – Oedogoniales. Family -Oedogoniaceae. Genus – Oedogonium. Oedogonium is a freshwater , filamentous alga and occurs in ponds, lakes and stagnant water. The filaments are attached to rocks. Some are epiphytic on aquatic plants.
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.
