What are the 2 classes of Anthophyta?
What are the 2 classes of Anthophyta?
The Anthophyta are divided into two major groups: dicots and monocots. The names refer to the embryonic leaves called cotyledons; monocots have one cotyledon, dicots have a pair. Corn, lilies, and grasses are monocots; peas, beans, peanuts, and maple trees are dicots.
How many classes are in Anthophyta?
There are two classes within this group: the Monocotyledoneae with one seed leaf (cotyledon) in the seed, and the Dicotyledoneae with two seed leaves.
Is Anthophyta a class?
Orders and classes On the other hand the two classes within the anthophyta, monocotyledones (monocots) and dicotyledones (dicots) are frequently mentioned.
What is phylum or division Anthophyta?
The Anthophyta, the angiosperms or flowering plants, is the largest and youngest phylum of plants and the one whose members dominate the vegetation of the modern world.
What is the difference between Coniferophyta and Angiospermophyta?
Members of division coniferophyta have cones and needle- like leaves. They include conifers, pines, cedar and cypress. Division angiospermophyta has two classes namely; monocotyledonae and dicotyledonous. Members of class monocotyledon, fibrous root system and leaves with parallel venation.
What makes Anthophyta unique?
Anthophyta produce flowers and their seed is enclosed inside the ovary or fruit. The presence of flowers is the easiest way to distinguish them from other plant phyla.
Where can you find Anthophyta?
Plants adapted to extreme cold (alpines) and extreme heat (cacti) fresh water and even marine plants (eel grass), although most are terrestrial.
What are the characteristics of Anthophyta?
Anthophyta have double fertilization : one male gamete fertilizes the egg ( making an embryo ) and the other male gamete fuses with 2 polar nuclei (making a triploid endosperm ). The seed is released surrounded by the ovary, as a fruit.
What is the common name for Anthophyta?
Hornworts are a plant type that is a non-vascular bryophyte with rhizoids. Learn about the classification of hornworts, group distinctions, overall characteristics, and some interesting facts. Cryptogams are a type of plant that doesn’t use typical stems, roots, leaves, or seeds to reproduce, using spores instead.
What are characteristics of phylum Anthophyta?
Anthophyta produce flowers and their seed is enclosed inside the ovary or fruit. The presence of flowers is the easiest way to distinguish them from other plant phyla. Though some of the flowers are large and obvious, others are smaller and more difficult to identify.
How many classes are in Coniferophyta?
As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important….Conifer.

What are the examples of Angiospermophyta?
Angiospermophyta
- Has vascularisation.
- Have leaves, roots and stems (individual species may be highly variable in structure)
- Reproduce by seeds produced in ovules within flowers (seeds may develop in fruits)
- Examples include all flowering plants and grasses.
Is Anthophyta vascular or nonvascular?
All members of the phylum Anthophyta are vascular.
What is unique about Anthophyta?
The distinctive feature of this group is the flower, a cluster of highly-specialized leaves which participate in reproduction. Not all flowers are as conspicuous as the Magnolia blossom in the picture above; oaks, ivy, and grasses also produce flowers, but because they are not as showy we often do not notice them.

What are the classes of Angiospermophyta?
Phylum Angiospermophyta is divided into two classes according to the number of cotyledons in their seeds. Angiosperms with two cotyledons such as beans and peanuts are placed under Class Dicotyleonidae or dicots. Those with only one cotyledon such as corn and rice are placed under Class Monocotyledonidae or monocots.
What are Angiospermophyta?
Angiospermophyta. Has vascularisation. Have leaves, roots and stems (individual species may be highly variable in structure) Reproduce by seeds produced in ovules within flowers (seeds may develop in fruits) Examples include all flowering plants and grasses.
