Which bryophyte is heterosporous?
Bryophytes are not heterosporous. They are homosporous – which means they produce spore of only one kind.
Is bryophytes Homosporous or heterosporous?
These plants have a different mechanism that prevents the fusion of male and lady gametes in the bisexual gametophyte. So bryophytes are homosporous.
Are seed plants heterosporous?
Whereas lower vascular plants, such as club mosses and ferns, are mostly homosporous (produce only one type of spore), all seed plants, or spermatophytes, are heterosporous. They form two types of spores: megaspores (female) and microspores (male).
Are all Moss heterosporous?
Mosses are heterosporous, which means they make two distinct types of spores; these develop into male and female gametophytes. ... Ferns follow a pattern of development similar to that of mosses, although most (but not all) ferns are homosporous.
What is the life cycle of moss?
The life cycle of a moss, like all plants, is characterized by an alternation of generations. A diploid generation, called the sporophyte, follows a haploid generation, called the gametophyte, which is in turn followed by the next sporophyte generation.
Does Moss show Heterospory?
> Option A:Funaria, also known as Moss belongs to phylum Bryophyta. Bryophytes are homosporous and also Funaria is found near water. ... Since Bryophytes are homosporous, they do not show heterospory.
How are the different types of bryophytes different?
Bryophytes are divided into three divisions: I. Ilepatieopsida (Liverworts): Liverworts are the simplest bryophytes. They grow on moist rocks and wet soil. Their plant body is gametophyte. There are two forms of gametophytes. Some have thallus body. Thallus is flat or ribbon-like. It is attached to soil by means of rhizoids. Example: Marchantia.
How are liverworts different from other bryophytes?
Liverworts (shown below) are extremely small plants characterized by flattened stems and undifferentiated leaves, as well as single-celled rhizoids. Liverworts can be distinguished from other bryophyte species by the presence of membrane-bound oil bodies within their cells, compared to other species which do not contain enclosed lipid bodies.
Is the Pteridophyte a heterosporous or homosporous plant?
Pteridophytes or ferns belong to the class of vascular plants. Depending on the life cycle of the pteridophytes, it can undergo alternation of generation based on homospory or heterospory. Homospory is a phenomenon in which only one type of spore can be seen. Such ferns are referred to as Homosporous Pteridophytes.
Are there male and female gametophytes in pteridophytes?
It is characterized by morphologically identical spores that germinate to produce bisexual (both male and female) gametophytes in pteridophytes but either bisexual or more usually, unisexual (either male or female) gametophytes in bryophytes. Each mature gametophyte bears gametangia (sex organs) that produce gametes.
