Detailed explanation-1: -Vegetative Reproduction in Chara Bulbils: Bulbils are small, spherical or oval bodies that develop on the shoot or root nodes of Chara. They detach and germinate into new plants. Amorphous Bulbils: Amorphous bulbils are an aggregation of cells that develop at the nodes. They detach and germinate into new plants.

Detailed explanation-2: -Reproduction: In Chara it takes place by vegetative and sexual method. 1. Vegetative reproduction: It takes place as under: (i) By amylum stars: a star-shaped propagative body densely filled with starch and formed about the lower nodes of certain species of Chara.

Detailed explanation-3: -Vegetative structure It is attached to the substratum by rhizoid. The axis has nodes and internodes. Nodes: Each node has two types of branches: Branches of limited growth or leaves: Several braches of limited growth form whorl at nodes.

Detailed explanation-4: -The stipulodes are short unicellular outgrowths developed from the lower nodes of the branches of limited growth (branchlets). In most of the species of Chara, the number of stipulodes at each node is twice the number of branchlets. Such species are called bistipulate, e.g., C. tomentosa, C.
