Fungi
|
- Fungi are eukaryotic organisms; i.e., their cells contain membrane-bound organelles and clearly defined nuclei.
- organisms of the kingdom Fungi, which includes the yeasts, rusts, smuts, mildews, molds, and mushrooms. There are also many funguslike organisms, including slime molds and oomycetes (water molds), that do not belong to kingdom Fungi but are often called fungi; many of these funguslike organisms are included in the kingdom Chromista. Fungi are among the most widely distributed organisms on Earth and are of great environmental and medical importance. Many fungi are free-living in soil or water; others form parasitic or symbiotic relationships with plants or animals.

Bryophytes
(1)
Usado por:
mosses, liverworts, hornworts
|
- traditional name for any nonvascular seedless plant—namely, any of the mosses (division Bryophyta), hornworts (division Anthocerotophyta), and liverworts (division Marchantiophyta). Most bryophytes lack complex tissue organization, yet they show considerable diversity in form and ecology. They are widely distributed throughout the world and are relatively small compared with most seed-bearing plants.

Algae
(2)
Usado por:
alga
|
- any of a diverse group of chiefly photosynthetic and aquatic plantlike organisms that range from unicellular to large multicellular forms, are typically classified as protists, and include the green, yellow-green, brown, golden-brown, and red algae in the eukaryotes and especially formerly the cyanobacteria in the prokaryotes
- Note: While multicellular algae often resemble plants, they lack the true roots, leaves, and stems characteristic of vascular plants.

marine algae
Usado por:
Seaweed
|
- Restricted exclusively to saline or brackish ocean environments.
- Marine algae live naturally in seas and oceans around the world. They include seaweeds and tiny plants suspended in the water. They can look like green flakes, greenish bundles or brownish dots.

Phaeophyceae
Usado por:
brown algae
|
- A class of algae, common in cold waters along continental coasts. Species colour varies from dark brown to olive green, depending upon the proportion of brown pigment (fucoxanthin) to green pigment (chlorophyll).
- Brown algae vary in form and size from small filamentous epiphytes (Ectocarpus) to complex giant kelps that range in size from 1 to more than 100 metres (3.3 to 330 feet; Laminaria, Macrocystis, Nerocystis). Other brown algae can be found attached to rocky coasts in temperate zones (Fucus, Ascophyllum) or floating freely (Sargassum). Freshwater species are rare. Brown algae multiply by asexual and sexual reproduction; both the motile zoospores and gametes have two unequal flagella. Some seaweed species have gas-filled bladders (pneumatocysts), which keep photosynthetic parts of the algal thallus floating on or near the surface of the water.

Pteridophyta
(2)
|
- lower vascular plant, any of the spore-bearing vascular plants, including the ferns, club mosses, spike mosses, quillworts, horsetails, and whisk ferns. Once considered of the same evolutionary line, these plants were formerly placed in the single group Pteridophyta and were known as the ferns and fern allies. Although modern studies have shown that the plants are not in fact related, these terms are still used in discussion of the lower vascular plants.
- a division of vascular plants coordinate with Bryophyta and Spermatophyta and coextensive with the subdivisions Psilopsida, Lycopsida, Sphenopsida and the class Filicineae of the Pteropsida

Hemerocallis L.
Usado por:
daylily, daylilies
|
- daylily, any plant of the genus Hemerocallis of the family Hemerocallidaceae, consisting of about 15 species of perennial herbs distributed from central Europe to eastern Asia. Members of the genus have long-stalked clusters of funnel- or bell-shaped flowers that range in colour from yellow to red and are each short-lived (hence “day” lily). Daylilies also have fleshy roots and narrow, sword-shaped leaves that are grouped at the base of the plant.
- The daylily fruit is a capsule. Some species of Hemerocallis are cultivated as ornamentals or for their edible flowers and buds.
