Each pollen grain contains two cells: one generative cell that will divide into two sperm, and a second cell that will become the pollen tube cell. In the spring, pine trees release large amounts of yellow pollen, which is carried by the wind.

A plant kingdom is further classified into subgroups. Classification is based on the following criteria: 1. Plant body: Presence or absence of a well-differentiated plant body. E.g. Root, Stem and Leaves. 2. Vascular system: Presence or absence of a vascular system for the transportation of water and other substances. E.g. Phloem and Xylem. 3. Seed...
Thallophytes lack a well-differentiated body structure and the plant body is thallus like. Thallophyta includes plants with primitive and simple body structures. The plant body is thallus, they may be filamentous, colonial, branched or unbranched. Examples include green algae, red algae and brown algae. Common examples are Volvox, Fucus, Spirogyra,...
Bryophytes do not have vascular tissues. The plant body has root-like, stem-like and leaf-like structures. Bryophytes are terrestrial plants but are known as “amphibians of the plant kingdom” as they require water for sexual reproduction. They are present in moist and shady places. Bryophyta includes mosses, hornworts and liverworts. Some of the co...
Pteridophytes have a well-differentiated plant body into root, stem and leaves. They have a vascular system for the conduction of water and other substances. Some of the common examples are Selaginella, Equisetum, Pteris, etc. More Details: Pteridophyta
Gymnosperms have a well-differentiated plant body and vascular tissues. They bear naked seeds, i.e. seeds are not enclosed within a fruit. Some of the common examples of gymnosperms are Cycas, Pinus, Ephedra, etc.
Angiosperms are seed-bearing vascular plants with a well-differentiated plant body. The seeds of angiosperms are enclosed within the fruits. Angiosperms are widely distributed and vary greatly in size, e.g. Wolffia is small measuring about 0.1 cm and Eucalyptus trees are around 100 m tall. Angiosperms are further divided into monocotyledons and dic...
- Kingdom Monera. Bacteria are placed in the “Kingdom Monera” category within the Five kingdom classification system. Characteristics of Monerans. They have essential characteristics such as the following
- Kingdom Protista. character of Protista. The following are some of Protista’s remarkable features: They are organisms that are both unicellular and eukaryotic in structure.
- Kingdom Fungi. Mould, mushrooms, and yeast are types of fungi. They are useful for a wide number of applications, both in the domestic and the commercial world.
- Kingdom Plantae. Features of Kingdom Plantae. All eukaryotic organisms that include chloroplasts are categorized within the Plantae kingdom. The nature majority of them are autotrophic, but some are heterotrophic.
Characteristic features of Plant Kingdom. These living organisms are made of eukaryotic cells and are multicellular. The cells have a cell wall which is made of cellulose. These are autotrophic and synthesize food by photosynthesis due to the presence of chloroplasts.
- Bryophytes are so called because even though they are terrestrial plants, they require water for their fertilization process. The sperms are carrie...
- Amphibians are organisms, which can survive both in water and on land but they require water for sexual reproduction. Pteridophyte includes terrest...
- Based on the system of classification proposed by A. W. Eichler (1875 -78), the plant kingdom is divided into two subkingdoms Cryptogamae and Phane...
- On the basis of presence or absence of flowers and seeds, Eichler classified plant kingdom into two sub-kingdoms namely Cryptogamae (absence of flo...
Plants possess cell walls containing cellulose. Most plants reproduce sexually, but they also have diverse methods of asexual reproduction. Plants exhibit indeterminate growth, meaning they do not have a final body form, but continue to grow body mass until they die.
Plants possess cell walls containing cellulose. Most plants reproduce sexually, but they also have diverse methods of asexual reproduction. Plants exhibit indeterminate growth, meaning they do not have a final body form, but continue to grow body mass until they die. Plant sex cells and sex organs are classified using the same system as those ...
