Incorrect Statement: Biflagellate zoospores are present in brown and red algae.
Brown and red algae do not produce biflagellate zoospores. Instead, biflagellate zoospores are characteristic of green algae.
Explanation:
1. Fucus is oogamous and has a frond with a midrib.
- Fucus is a brown algae commonly known as rockweed. It exhibits oogamy, which is a type of sexual reproduction where two gametes (egg and sperm) are involved.
- The female gamete (egg) is large and non-motile, while the male gamete (sperm) is small and motile.
- Fucus has a thallus structure that is commonly referred to as a frond. The frond is flat and leaf-like, with a midrib running through the center.
2. Volvox is oogamous and colonial.
- Volvox is a green algae that belongs to the Chlorophyta phylum. It is a colonial organism, meaning it exists as a group of individual cells that are connected and function together.
- Volvox also exhibits oogamy, where the female gamete (egg) is larger and non-motile, while the male gametes (sperm) are smaller and motile.
- The colonies of Volvox are spherical in shape and consist of numerous cells embedded in a gelatinous matrix.
3. Hydrocolloids are produced by both red and brown algae species.
- Hydrocolloids are gel-forming substances that are extracted from certain types of algae.
- Red algae, also known as Rhodophyta, are an important source of hydrocolloids such as agar and carrageenan.
- Brown algae, also known as Phaeophyta, are another source of hydrocolloids, including alginates.
4. Biflagellate zoospores are not present in brown and red algae.
- Biflagellate zoospores are unicellular structures that possess two flagella, which are whip-like appendages used for movement.
- While green algae exhibit biflagellate zoospores as part of their life cycle, brown and red algae have different reproductive structures.
- Brown algae produce motile gametes called anisogametes, which are non-flagellated. Red algae, on the other hand, have non-motile gametes (non-flagellated) that are released from specialized structures called conceptacles.
