Question

Mention the ploidy of the Gemma cell in marchantia.

Answer 1

The systematic position of the marchantia belongs to the plantae kingdom, bryophyte division, hepaticopsida class, marchantiales order, and marchantiaceae family and marchantia genus. In the habitat there are a total 65 species found and grown under the moist, shady place. 11 species found in the western Himalayas. In Kashmir, south India, Assam and Bengal mostly found m.palmate species. In himachal m.simlana and in the Punjab and kumaon hills mostly found the m.nepale species.

Complete answer:
The gametophyte is the dichotomously branched and dorsoventrally morphology in the plant body prostrate. The presence of the district midrib in each branch in the shallow groove and outline of the underlying air chambers in the polygonal area of the demarcate. In the air pore that are present in the center of each polygonal area and Gemma cups are present along with the midrib. Apical notch in which each branch has grown out and situated at the apex in the grooves. The reproduction of the Gemma cups in the dorsal surface along midrib region under the lobed, spiny and hyaline. The biconvex Gemma arises and stalks from the floor of the Gemma cup also constructed in the middle and two notches possess a row towards the apical cells. The germination starts immediately when Gemma combines to contact with the ground. And the Gemma cells in the ploidy during the marchantia are haploid, X in nature.

Note: Gemma cups can be stored six months in the refrigerator stabs and Gemma produced from the marchantia plant that obtained the vegetative propagules in the simple clonal propagation of the lines. In the liverwort, mosses, and thali of the bryophytes the Gemma small shaped cups mostly found in it. New individuals obtained during the separation of the Gemma cells from the parent cells.
