General characteristics of ferns

They originated in the Devonian. They reached their biological flowering in the Carboniferous, becoming the main forest-forming group. The remains of the forests have formed vast deposits of coal.
The largest number of species in the tropical zone.
They prefer moist habitats, because male gametes are mobile, and moisture is needed to move the sperm to the egg.
There are tissues and organs.
The life cycle is dominated by the diploid sporophyte.
Reproduction is sexual and asexual (sporulation).
The organs of sexual reproduction are multicellular.

Division Ferns

Currently, the department has approximately 12,000 species.

Life forms: grasses, trees (Fig. 1) and creepers (several tropical species). There are water forms, for example, salvinia floating (Fig. 2).

Rice. 1 Fig. 2

fern leaves - fronds- whole or complexly dissected with a well-developed conduction system. The development of the leaf comes from the "snail" (Fig. 3).

Leaves can be differentiated into sterile and fertile, for example, in the ostrich (Fig. 6), have a sterile and fertile part (leaf, Fig. 4) or perform both functions simultaneously (most ferns, Fig. 5). The fertile leaves of the ostrich do not photosynthesize.

Rice. 3 Fig. 4 Fig. five

Most ferns have an underground rhizome and well-developed adventitious roots (Fig. 7).

Rice. 6 Fig. 7

The life cycle of ferns includes the alternation of a haploid gametophyte and a diploid sporophyte with a predominance of the sporophyte. In the life cycle, there is an alternation of sexual and asexual reproduction (Fig. 8).

During asexual reproduction, paired outgrowths are formed on the underside of the leaf - sori(Fig. 9). The sorus is a stem and a veil that covers the bottom of the spherical sporangia (Fig. 10), extending from the base of the stem. In sporangia, spore mother cells are formed, which divide by meiosis to form haploid cells that become spores. In dry weather, the edges of the spathe are folded back, and the sporangium shell bursts due to uneven thickening of the walls of the cells that form it.

Rice. 9 Fig. 10

From spores that have fallen into a moist, lit place, a haploid fern gametophyte develops - sprout- in the form of a heart-shaped plate with numerous rhizoids. On its lower side, antheridia with spermatozoa and archegonia with eggs are formed. Like mosses, ferns need water to thrive. On it, polyflagellated fern spermatozoa swim to archegoniums. There, the sperm fuse with the egg, forming a diploid zygote. A new diploid plant grows from it.

In the forests of the temperate zone, the most common are the male boletus, the female boletus, and the bracken.

Department of Lycopods

The shoot is creeping, dichotomously branching.
leaflets (phylloids)small simple with one central vein.
Reproduction is sexual and asexual (sporulation).
The life cycle is dominated by the diploid sporophyte.

The representative of the club mosses, often found in our country, is the club moss (Fig. 11).

In the life cycle of club mosses, like all ferns, there is an alternation of sexual and asexual reproduction (Fig. 12). At the ends of the shoots of the club moss, erect spore-bearing spikelets- strobili. Spore-bearing spikelets are covered with modified scaly leaves - sporophylls- on which sporangia are formed. In sporangia, meiosis produces haploid spores. Mature spores spill out, and a haploid outgrowth develops from them. In many species of club moss, the growth develops underground for several years, feeding heterotrophically, mainly due to symbiosis with the fungus. On a mature gametophyte, archegonia with eggs and antheridia with spermatozoa are formed. After fertilization, the zygote develops into a diploid sporophyte, which feeds on the gametophyte until it reaches the ground, where it begins to photosynthesize.

Horsetail department

An ancient group of vascular plants, currently represented by about 30 species.

The stems are hollow, consisting of individual segments and performing the function of photosynthesis (Fig. 13). To increase strength, bundles of sclerenchyma fibers pass under the epidermis, forming ribs on the surface of the stem. In addition, small silica crystals are deposited in the stems of horsetails, which increase their rigidity.

Under the ground, horsetail forms a dense network of rhizomes that serve for vegetative reproduction and winter survival.

In the spring, spore-bearing shoots grow out of the ground. They are brown in color because they do not contain chlorophyll and live off the nutrient reserves accumulated last year. On their sporophylls, as a result of meiosis, haploid spores are formed, which have special filamentous outgrowths that change shape depending on humidity. This allows them to leave the sporangium more easily and spread more widely. They give rise to a haploid outgrowth. The life cycle of horsetails is similar to life cycle ferns (Fig. 14).

When to sow fern spores

If the sori darken, then the spores are ripe. Take the vayu and put it in a paper bag. After a while, the bag will contain a dried fern leaf and a bunch of spore powder. For most ferns, it doesn't matter when they are sown. Although there are exceptions: controversy Osmund germinate only when sown freshly harvested. It is also better not to delay the sowing of the rest: germination, although slowly, falls, and the germination of stale spores is delayed. Fresh spores germinate in about a week or two.

Taking into account the fact that it takes up to two months for the formation of seedlings, then the same amount for the development of roots, many authors advise sowing in autumn or early winter, and then fern seedlings will develop by the end of winter-early spring.

Schmulberg, the owner of a nail business, calls his son and says:
- Izya, I want to temporarily entrust you with the management of the company: I have been working without rest for so many years that I finally need to rest. I'm leaving for 3 months in the Bahamas and I want you to manage the company all this time, solve all the problems and not bother me.

- Izzy, how did you manage to set up sales like that.
- It's very simple: I gave an advertisement. Won! Do you see the poster hanging on the wall?
Schmulberg looks at the poster - and sees that it depicts Christ crucified on the cross, and at the bottom there is an inscription: "Schmulberg's nails - thanks to them he has been holding on for 2000 years!". Schmulberg:
- Izzy, what did you do. Take down all these posters now, and remember: never use the name and image of Jesus Christ in advertising! Do you want the pogroms to start again?!
