Under favourable conditions of moisture, the secondary protonemata are formed from any detached or injured portion … Occurrence of Chara 2. Taxonomic Status. Sexual reproduction - Sexual reproduction is Oogamous. The plant body of Chara is haploid. Chara is a genus of charophyte green algae in the family Characeae. Vegetative reproduction takes place by tubers, and special alga structures known as "amylum stars" and "secondary protonema." Chara reproduces by vegetative and sexual methods. They are found in Chara. Such structures are found in Chara which help in vegetative propagation. Chara (alga) explained. (iv) By secondary protonema. Many of these events likely represent secondary gains in Chara complexity via sub- and neofunctionalization. Such vegetative structures develop in Chara which develop into new plants. Both, specific gains/expansions and losses, can be attributed to the Chara lineage . Modes of cytokinesis: a cleavage furrow with persistent telophase spindle as seen in Klebsormidium and a phragmoplast seen in Chara that differs from that of land plants, as the cell plate in Chara shows little centrifugal growth but is formed simultaneously across the cell’s equator. Numerous Chara species are recognized but I can't distinguish them. Secondary Protonema: Sometimes protonema may be formed by a method other than from germination of spores.These are secondary protonema. (iii) By tubers. ADVERTISEMENTS: In this article we will discuss about:- 1. Cell Structure 4. They are found in fresh water, particularly in limestone areas throughout the northern temperate zone, where they grow submerged, attached to the muddy bottom. The sexual re… They reproduce both vegetatively and sexually. Features 5. Sex organs are macroscopic and are produced on the branches of … Occurrence of Chara: Chara is represented by about 188 species, out of which 30 spe­cies are found in India. Life Cycle 7. Such bodies are full of starch. Such structures are found in Chara which help in vegetative propagation. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures. Reproduction 6. In absence of a WGD, gene family expansions resulted from gene duplication and differential loss. Since Chara species are algae, they bear no flowers or fruits. Secondary protonema is similar morphologically to primary protonema and also gives rise to gametophore initials. It is commonly known as “stonewort”. Vegetative reproduction takes place by Amylum stars, Root bulbils, Amorphous bulbils and secondary protonema. (v) By bulbils. The vegetative reproduction takes place by the formation of amylum stars, bulbils and secondary protonema. Plant Body of Chara 3. Chara is a genus of charophyte green algae in the family Characeae.They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures.They are found in fresh water, particularly in limestone areas throughout the northern temperate zone, where they grow submerged, attached to the muddy bottom.
