Is Pogonatum a flowering plant?
Is Pogonatum a flowering plant?
Pogonatum is a genus of mosses — commonly called spike moss — which contains approximately 70 species that cover a cosmopolitan distribution. It can be seen mostly in Asian countries with a tropical climate.
What is the scientific name of Pogonatum Moss?
PogonatumPogonatum / Scientific name
Pogonatum urnigerum is a species of moss in the family Polytrichaceae, commonly called urn haircap.
What are characteristics of mosses?
Mosses have green, flat structures that resemble true leaves, which absorb water and nutrients; some mosses have small branches. Mosses have traits that are adaptations to dry land, such as stomata present on the stems of the sporophyte.
Does Pogonatum have stomata?
It is the fertile portion of the capsule (Fig. 10 B-D)). The longitudinal section passing through the region shows the outermost single layer epidermis which lacks stomata.
How does selaginella reproduce?
Selaginella reproduces by two methods: Vegetatively and by formation of spores.
Do all bryophytes have Protonema?
Bryophytes do not have true leaves (megaphylls). Protonemata are characteristic of all mosses and some liverworts but are absent from hornworts.
What is the importance of moss?
Ecologically, mosses break down exposed substrata, releasing nutrients for the use of more-complex plants that succeed them. They also aid in soil erosion control by providing surface cover and absorbing water, and they are important in the nutrient and water economy of some vegetation types.
What is classification of mosses?
BryophytaMoss / Scientific name
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (/braɪˈɒfətə/, /ˌbraɪ. əˈfaɪtə/) sensu stricto. Bryophyta (sensu lato, Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts.
What is Elaters in botany?
Definition of elater : a plant structure functioning in the dispersal of spores: such as. a : one of the elongated filaments among the spores in the capsule of a liverwort. b : one of the filamentous appendages of the spores in the horsetails.
What is the life cycle of Selaginella?
Selaginella like other pteridophytes show alternation of generations. The life cycle alternates between diploid sporophyte and haploid gametophyte generation. This type of life cycle is called a haplo-diplontic life cycle. The sporophyte is the dominant phase in the life cycle.
How do you care for Selaginella?
Keep the soil moist but never soggy and avoid using cold water. A Selaginella plant becomes totally dormant and the leaves roll into tight little brown balls when there is no moisture. Once the Selaginella is watered, it turns green and starts to grow again. A Selaginella plant needs very little plant food.
