In this article we will discuss about the anatomy of anthoceras with the help of a suitable diagram. The thallus of Anthoceros is several layers thick but it lacks a definite midrib. In a thallus all cells are thin-walled (Fig. 3.2B). On the ventral surface of the thallus are smooth colourless rhizoids. Stomata-like pores occur on the undersurface. On the [...]
In this article we will discuss about the morphology of anthoceros with the help of a suitable diagram. Anthocerotae, or hornwort, is a distinct evolutionary group of thalloid liverworts, without an internal differentiation of thallus, each cell of which has a single large chloroplast and an associated pyrenoid. The 'horn' describes the sporophyte, a tapered structure of indeterminate growth. Due [...]
In this article we will discuss about the anatomy of marchantia with the help of a suitable diagram. Internally, in a cross-section (Fig. 2.7A, B) the thallus is made up of two zones; upper assimilatory and lower storage zone. The assimilatory zone is narrow, it is made up of a single layer of air chambers which enclose assimilatory filaments. Each [...]
