The kingdom Plantae constitutes large and varied groups of organisms. All are eukaryotic, multicellular with differentiated tissues, and photosynthetic. There are more than 300,000 species of cataloged plants. Of these, more than 260,000 are seed plants. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom.
KINGDOM PLANTAE. Although plants differ in size and appearance, most people can easily identify the members of kingdom Plantae. Kingdom Plantae contains organisms that are eukaryotic, have cell walls, and make food by photosynthesis. Most plants need sunlight to carry out photosynthesis.

Kingdom Plantae includes green, brown and red algae, liverworts, mosses, ferns and seed plants with or without flowers. They have the following characteristics: 1. They are multicellular organismswith walled and frequently vacuolate eukaryotic cells. 2. These contain photosynthetic pigment in plastids. The principle mode of nutrition is photosynthe...
They are simple, autotrophic non-vascular plants. They have unicelled sex organs and no embryo formation. These grow in specialized habitats: 1. Cryophytes:These grow on snow or ice. 2. Thermophytes:These grow in hot water. 3. Epiphytes:These are those algae that grow on other plants (algae, angiosperms). Examples include Oedogonium, Cladophora, Va...
Bryophyta (Gk: Bryon = moss; phyton = plants) is the grouping that consists of the simplest and primitive land plants. We also regard these as ‘the amphibians of the plant kingdom’. Bryophytes are most common in moist and shady places. Some bryophytes also grow in diverse habitats like extremely dry or watery habitats. They reproduce sexually. Anth...
The pteridophytes (Gk. Pteron = feather and phyton = plants) refers to all those plants with feathers like fronds of ferns. They do not have flowers or seeds. These plants are mostly terrestrial. They prefer shady habitats. They have a Sporophytic plant body. The pteridophyte usually has a single apical cell with three cutting faces in the shoot ap...
The angiosperms, or flowering plants, are the most dominant and ubiquitous vascular plants of present-day flora. These plants are primarily responsible for changing the green and yellow melancholy of the earth’s vegetation. They do so by their beautiful and colorful brightness and fragrance of their flower. The term angiosperm means ‘enclosed seed’...
Question: Write a short note on gymnosperms from Kingdom Plantae. Answer: Living gymnosperms are mostly perennials, xerophytic, evergreen, arboreal and woody plants. We can find them growing as wood trees, bushy shrubs or rarely as climbers (e.g., Gnetales). They are never herbs or annuals. The external features of these are: 1. The plant body is s...
Q1. Give the outline for kingdom plantae. Answer: Kingdom Plantae is classified into the following groups: Thallophyta: Algae belong to this group. They have chlorophyll. They are phototrophic. They are mostly aquatic. Other members include fungi. Bryophyta: They are found in cool, damp areas. They have thallus like plant body attached to the subst...
Sep 4, 2018 · 5,642. Classification of Kingdom Plantae. A plant kingdom is further classified into subgroups. Classification is based on the following criteria: Plant body: Presence or absence of a well-differentiated plant body. E.g. Root, Stem and Leaves.
Gymnosperms and Angiosperms under Plantae . Let us also look at classification within angiosperms to understand some of the concerns that influenced the classification systems. The earliest systems of classification used only gross superficial morphological characters such as habit, colour , number and shape of leaves, etc. They
Figure 3. All members of the plant kingdom can be classified based on their morphological differences. Some biologists classify algae in the Protista kingdom, while other plant biologists would classify them as the sim-plest member of the plant kingdom.
