Lichens:- Both the partners gain water and minerals nutrients mainly from atmosphere, through rain and dust.

Bryophyta:- The moss namely Sphagnum is capable of soaking water 18 times of its own weight. Therefore, gardeners use it to protect from drying while taking the plants from one place to another. Both the partners gain water and minerals nutrients mainly from atmosphere, through rain and dust. The leaf is linear to lanceolate and the leaf base is sheathing. Rhizoids arise from the rhizome like structure.

The zygote secretes a wall and divides transversely into an upper and a lower cell.  The cells of the foot are smaller and with dense cytoplasmic contents than those of the above living cells of the seta with poor cytoplasmic contents.

These cavities open by narrow slits. Due to the presence of these algal colonies, the colour of the thallus becomes dark green.

The primary stalk cell gives rise to stalk and primary antheridial cells divides by two vertical walls at night angles to each other and then by two transverse walls thus forming three tiers with four cells in each tier Side by side the sterile roof initial cell increases in side around the antheridium to form antheridial chamber.

Some Topics of Botany

The cover initial divide by vertical wall and form four cover cells. The primary neck canal cell divides and redivides and gives rise to four to six neck canal cells. The primary venter cell divides transversely to form venter canal cells and egg. The zygote or oospore is the first cell of the sporophyte.

Oospore or zygote first increases in size and fills the venter and then begins to divide. The zygote first of all divides by a vertical division and then again divides by a vertical division at right angles to the plane of first division. In this way eight celled embryo is forming having two tiers of four cells each. The upper tier of four cells forms the capsular region while the lower tier forms the bulbous foot.
