Which ten plants reproduce by spores?
Ferns Mosses Liverworts Horsetails Lycopods Clubmosses Quillworts Selaginella Azolla Marsilea
Is selaginella a homosporous or a heterosporous plant?
Selaginella is a heterosporous plant, meaning it produces two types of spores – megaspores and microspores. Megaspores develop into female gametophytes, while microspores develop into male gametophytes.
What plants has roots stems and leaves but does not produce seeds?
Examples of plants that have roots, stems, and leaves but do not produce seeds are flowers. Flowers have roots, stems, and leaves; and reproduce by pollination with the help of bees, and other insects.
What structures might be found on the underside of fern leaves?
On the underside of fern leaves, you may find structures called sporangia, which are clusters that contain spores. These spores are crucial for fern reproduction. Additionally, you may also find sori, which are groups of sporangia clustered together.
What is Pteridophytes?
Pteridophytes are a group of vascular plants that reproduce via spores. They include ferns, horsetails, and club mosses. These plants have well-developed vascular tissues for conducting water and nutrients.

What type of spores do lycopodium produce?
Lycopodium is homosporous producing only one type of spores.
What type of spores does Lycopodium produces?
Lycopodium produces spores known as homosporous spores, which are all of the same size and shape, allowing for a uniform dispersal method.
Are all spores in the same sporangium similar?
no selaginella has megaspores and microspores
Are selaginella seedless plants?
Yes, Selaginella have megaspores and microspores not seeds like the naked seeds of Conifers and Cycads and the Seeds of Angiosperms. Selaginella belong to the Clubmoss Group Lycopodiopsida see related link.

Spores of these plants were once used as flash powder?
Lycopodium, which is in the genus club mosses
What is Lycopodium spore method of analysis?
It is an important technique for powdered drug ,especially when chemical & other method fail as accurate measure of quality. Lycopodium is composed of spores of lycopodium elavatum.I. Each spore is tetrahedral in shape, The base is rounded and the threeside wallmakes the three well marked covering ridge, which join one other at filled with fixed oil. The spore are exceptionally uniform in size(25µm) and the shape tetrahedral so that one can always know that a definite no. of spore present in particular weight of lycopodium. On an average 94000 spores per mg of powdered lycopodium are present. Using this figure one can calculate the weight of any number of spores under any condition underthe microscope.
