Does marsilea have Sporocarp?

THE SPOROCARP of Marsilea is a unique botanical structure. When scarified and placed in water, the sorophore contained within the sporocarp gradually expands’ into a long gelatinous column many times the length of the sporocarp.

Is marsilea a pteridophyta?

Marsilea, Fern, and Horse-tail are examples of Pteridophytes. Pteridophytes are spore-producing vascular plants. Bryophytes are called the amphibians of the Plant Kingdom and they need water for fertilization.

What is the type of development of Sporangium in marsilea?

Marsilea is heterosporous i. e., it produce two types of spores—microspores and megaspores. These spores are produced in microsporangia and megasporangia, respectively. These sporangia are borne in special type of spore producing organ called sporocarp.

How many layers are present in marsilea Microspore?

Structure of Microsporangium: It is somewhat oval structure with a long stalk and is present laterally on the receptacle. It is smaller in size. It has a single layered jacket followed by two layers of tapetal cells. In the centre is present a cavity filled with microspore mother cells (Fig.

How does the Sporocarp of marsilea resemble a seed?

Morphology of Sporocarp: Each sporocarp is oval or oblong body or bean seed shaped. The portion where the sporocarp attaches with the pedicel is called the raphe. Above Raphe the sporocarp has two horn shaped parts called tubercles.

Is marsilea heterosporous pteridophytes?

Which is spore producing organ of Marsilea?

Spore producing organs: Marsilea is heterosporous i. e., it produce two types of spores— microspores and megaspores. These spores are produced in microsporangia and megasporangia, respectively. These sporangia are borne in special type of spore producing organ called sporocarp.

Where are microspores produced?

the anther
Microsporogenesis: Microspores are formed from microspore mother cells inside the anther. It is the process of formation of microspores from a pollen mother cell through meiosis division. The cells of sporogenous tissues undergo meiotic division to form microspore tetrad.

Does marsilea have vascular tissue?

Marsilea consists of vascular tissue. Belonging to the family of genus Marsilea, these organisms grow on semi-aquatic and aquatic ecosystems. The basic difference between Vascular and nonvascular plants is that while the former has a vascular system (xylem and phloem, the latter lacks it.
