• Pinus is a large, perennial, evergreen plant.
• Branches grow spirally and thus the plant gives the appearance of a conical or pyramidal structure. ...
• Sporophytic plant body is differentiated into roots, stem and acicular (needle-like) leaves (Fig.

What is the use of Pinus?

Pine oil from the wood, used in paints, varnishes, lacquers, pharmaceuticals, wetting agent in textiles, degreasing agent in leather manufacture, and as a synergist in insecticides. Also employed in paper and rubber industries, furniture polishes, floor waxes, shoe creams, metal polishes, and printing inks.

Why are pine trees bad?

Yes, all bryophytes are homosporous (i.e., they produce only one type of spores) including Marchantia and Polytrichum.

Is Psilotum Homosporous or heterosporous?

Psilotum is a fern with synangia formed by the fusion of three sporangia that bear the spores. The spores are of similar structure and hence they are homosporous. The spores germinate to form the gametophyte.

How Pinus Roxburghii is different from Pinus Wallichiana?

Homosporous is a condition in which identical spores, the same sized spores are produced. Such morphologically identical spores grow into bisexual gametophytes in some of the members (monoecious plants). Hence, in the homosporous condition, all spores would be of the same type.

Does Psilotum have vascular?

The genus Psilotum contains two species and one hybrid (P. complanatum, P. nudum, and P. x intermedium) of pantropical plants with whisklike green stems and scalelike appendages called “enations,” which may represent reduced leaves, but they contain no vascular tissue (veins).
