Question

Botanical snakes are
(a) Algae
(b) Fungi
(c) Bryophytes
(d) Pteridophytes

Answer 1

Hint: It is a vascular plant, which contains xylem and phloem. It disperses spores. It’s the first true land plant. Because pteridophytes produce neither flowers nor seeds, they are  sometimes mentioned as cryptogams.

Complete answer:
Pteridophytes (here, pteron means feather, and python means plant) constitute the foremost primitive seedless vascular plants that reproduce by means of spores. Like reptiles (which are the first true land animals that develop after amphibians)  they observe the first true land plants that evolved after bryophytes. Therefore, pteridophytes are sometimes called Botanical Snakes of the kingdom Plantae. They're also sometimes called “Amphibians is of plant kingdom” because like bryophytes they depend upon an external source of water for fertilization.
The characteristics of Pteridophytes:
- Pteridophytes are the first true land plants. - They're seedless, vascular cryptogams (meaning that their means of reproduction is hidden).
- Life cycle is heterologous diplohaplontic type. - Sporophyte is the dominant plant body while gametophyte may be a small, simple prothallus. - Sporophyte has true roots, stem and leaves. - In xylem, trachea (vessels) absent and, in phloem companion cells absent. - Spores develop in sporangia. - Sporangia are produced in groups of sporophylls. - Young leaves of sporophyte show circinate vernation. - Gametophyte develops small sessile antheridia (male) and partially embedded archegonia (female) . Sex organs multi- cellular and jacketed.
- Bryophytes are understood as the amphibians of Plantae, as they're primitive plants. - Algae are the photosynthesis organisms, as they possess photosynthesis processes. They will be unicellular, multicellular and colonised. - Fungi are the eukaryotic organisms, they depend on other organisms for their food mainly, dead and decayed.

Note:
Economic Importance of Pteridophytes are:
Ornamental value: Ferns arc grown as ornamental plants in gardens and houses for their attractive foliage. Drug: Rhizomes and petioles of Dryopteris obtained an anthelmintic drug. Food: Sporocarps of Marsilea are a huge source of starch and eaten for their nutritional value as food.
