Porphyra- The phylum rhodophyta includes the red algal species porphyra. It is frequently discovered in shallow water and has significant economic impact as an edible seaweed. - Polysiphonia- Polysiphonia belongs class Rhodophyceae. Most of the species are lithophytic (Growing on rock). Some are epiphytic growing on other algae. Polysiphonia large multiaxial annual or perennial thalli. Polysiphonia form thick tuft or dens bushes are brown or violet-red colour. They are attach by rhizoid to a rocky surface or other algae. - Chara- In chara, both male and female sex organ present on same plant. i.e. monocious. - Dictyota- A genus of brown seaweed in the Dictyotaceae family is called Dictyota. The majority of these species are found in tropical and subtropical oceans, and it is knwon that they contain a variety of compounds (diterpenes) that may be useful medically.

Which one of the following is wrong about Chara?
1 Upper oogonium and lower round antheridium
2 Globule and nucule present on the same plant
3 Upper antheridium and lower oogonium
4 Globule is male reproductive structure
Explanation:
Chara is a multicellular green alga. Sexual reproduction in Chara is oogamous. The male sex organ is called antheridium (globule). The female sex organ is called oogonium (nucule). Most species of chara is a monoecious plant i.e. globule (Antheridia) and nucule (oogonium) are present at the node on same plant - Globule present below the nucule i.e. oogonium are present at upper portion and antheridium is present at lower portion.

In Chlorophyceae, the mode of sexual reproduction is
1 isogamy
2 anisogamy
3 oogamy
4 all of these
Explanation:
In chlorophyceae the mode of sexual reproduction is either isogamaus or anisogamous or oogamous with specilised reproductive cells. Isogamous :- The fusing gametes are morphologicaly similar but physiologicaly differ called isogametes one represented by positive strain and other negative strain. Both fuse to form $2 \mathrm{n}$ zygospore. It is simplest and most primitive type as ulothrix chlamydomonas, spirogyra etc. Anisogamous: The fusing gametes morphologicaly and physiologicaly dissimilar called anisogametes small gamete is more active and large gamete is less active. Both fuse to form diploid zygote as chlamdomonas braunii, Eudorina. Oogamous : It is advanced type sexual reproduction. - Sex organ well developed, male sex organ called antheridia produced many motile male gametes called sperm, female sex organ called oogonium produced single large non motile female gamete called egg retained within the oogonium.
Porphyra- The phylum rhodophyta includes the red algal species porphyra. It is frequently discovered in shallow water and has significant economic impact as an edible seaweed. - Polysiphonia- Polysiphonia belongs class Rhodophyceae.
