What are Vascular plants? Name the
major groups of vascular
and
plants
non- vascular.
Answers
Vascular plants, also known as Tracheophytes are the groups of higher plants, categorized in kingdom ‘Plantae’. These are the green plants, with the specialized plant tissue called vascular tissues. This special issue is the main feature which varies them from the non-vascular plants. These two types of tissues are the xylem and phloem. the vascular plants are responsible for the transportation of water, minerals, and other products to different parts of the plants.
The vascular plants can grow up to a height, they are found on land, deserts, aquatic environments, etc. They include Angiosperms, Gymnosperms, Pines, Clubmosses, Ferns, etc. The plants with the vascular system have well-defined root and shoot systems, they also bear leaves, fruits, flowers, and wood.
Non-vascular plants are small and simple and include the liverworts or Haptophyta, hornworts or Anthocerotophyta, and mosses or Bryophyta. They are also known as bryophytes. Non-vascular plants are said as the most primitive form of land vegetation categorized under kingdom ‘Plantae’.
These plants are not well developed and lack true leaves, stems, and roots, mainly they have a poor transport system. This transport system consists of two tissues namely the xylem and phloem are responsible for carrying minerals and water to different parts of the plants.
Upcoming points are essential in order to differentiate between vascular and non-vascular plants:
1. Vascular plants are green plants, which have true leaves, stems, roots, and bear fruits and flowers, essentially they have specialized tissues (xylem and phloem) for transporting food, water, and minerals to all parts of the plant. These types of plants can grow much longer. Non-Vascular plants are short-height plants, with poorly developed roots and stems, do not bear fruits and flowers, or woods, and mainly lack a transport system carrying minerals, food, water, and gas.
2. Angiosperms, Gymnosperms, Ferns, Pines, Grasses, Sunflowers, Clubmosses, etc. are examples of some of the vascular plants while Liverworts, hornworts, and mosses are examples of non-vascular plants.
3. Vascular plants widely grow widely in every part, while non-vascular plants are specified to marshy, swampy, moist, and shady places.
4. Xylem and Phloem tissues (Vascular system) is the critical point to discuss, as these tissues help in carrying food, water, and minerals to all parts of the plants and these tissues are the specializations of vascular plants, while it is not found in non-vascular plants.
5. The life cycle of both the plants is the same, which means both types of plants go through the alternation of generations, but in vascular plants dominating phase is the sporophyte, which is diploid, and in non-vascular plants dominating generation is gametophyte, and the second is the sporophyte.
6. Vascular plants have a proper root system, which supports the plants to anchor the soil and get nutrients from it, whereas non-vascular plants instead of roots, they have rhizoids (small hairs to support the plant firmly).
7. Stems or shoot system is well developed in vascular plants and protects the plants, helps in the exchange of gases, photosynthesis, etc., in non-vascular plants true stems are absent.
8. Leaves of the vascular plants play a critical role in photosynthesis, which prevents the water loss, and stomata work in gas exchange, whereas in non-vascular plants true leaves are absent, and there is no special function or specialized tissues against the water loss and for gas exchange.
HOPE THIS HELPS!!!!!!!!
Answer:
okay we can be friends
Explanation:
A vascular plant is any one of a number of plants with specialized vascular tissue. The two types of vascular tissue, xylem and phloem, are responsible for moving water, minerals, and the products of photosynthesis throughout the plant.
