BASIS OF CLASSIFICATION:
- The classification of plants is based upon certain characteristics
- We may use such feature as basis like environmental conditions, methods of obtaining food, anatomy, life history, size of the body, the color of flowers, use in daily life, geographic distribution
What is the basis of classification of plant kingdom class 9?
The plant kingdom is further classified based on the following three criteria: Plant body. Vascular system. Seed formation.
What are the 5 classifications of plants?
The 5 classifications in the plant kingdom are thallophyta, bryophyta, pteridophyta, gymnosperms, and angiosperms.
What are the two main classifications of plants?
Plants are classified into two groups: nonvascular plants and vascular plants. Vascular plants are further divided into those that reproduce without seeds and those that reproduce with seeds. Seed plants are divided into those that produce seeds in cones and those that produce seeds in the ovaries of flowers.
What are 3 ways plants can be classified?
Plants are classified based on three charcteristics.Presence or absence of a differentiated body - root, stem and leaf.Presence or absence of vascular tissues - xylem and phloem.Presence or absence of seeds - cryptogams and phanerogams.
What are the different classifications of plants?

What are the 7 classifications of plants?
The classification system groups, in order from largest to smallest, are kingdom, phylum or division, class, order, family, genus, and species (Figure 2).
What are the four classifications of plants?
Plants can also be classified as grasses, herbaceous plants, woody shrubs, and trees.
How are plants classified 6?
Based on these characters most plants can be classified into three categories: herbs, shrubs and trees.
What is the method of arranging organisms into groups on the basis of similarities and differences called?
The method of arranging organisms into groups on the basis of similarities & differences is called classification. The taxonomy is the study of diversity & kind of organism & the evolutionary relationship among them. Organisms may be grouped into two broad categories on the basis whether they possess prokaryotic cells or eukaryotic cells.
What is the function of multicellular organisms?
In case of multicellular organisms the different groups of cells carry out specialized functions. Organism is photosynthetic or takes food from outside : Green plants perform photosynthesis and synthesise their own food. Animals cannot perform photosynthesis. They get food from outside.
Can animals do photosynthesis?
Animals cannot perform photosynthesis. They get food from outside. Grouping of organism may be done on the basis of body organization. For example, plants possess stem, root and leaves. Similarly, the animals possess specialized organs to perform different functions.
Is a cell eukaryotic or prokaryotic?
Cells are prokaryotic or eukaryotic : Organisms may be grouped into two broad categories on the basis whether they possess prokaryotic cells or eukaryotic cells. In case of prokaryotic cells the nuclei and other organelles are not clearly developed. The eukaryotic cells, on the other hand, have membrane-bound organelles, including a nucleus.
What is the basis of classification in the Plantae kingdom?
Earlier, for the plant kingdom, the basis of classification was cell walls. In the two kingdom classification system, all organisms with cell walls were included in the kingdom Plantae.
Why is classification important in plant evolution?
Classification provides phylogenetic linkages and relationships. So, it helps in the study of the evolution of plants.
What are the two kingdoms?
Similar phyla form a kingdom. There are two kingdoms: Kingdom Animalia and Kingdom Plantae.
What are the units of classification called?
The units of classification are called taxa. Each taxon is more general than the taxa below it. The members of the lower category resemble more with one another than the higher taxon. Initially, this classification system was based on appearance or morphology.
What is the arrangement of plants into different groups and sub-groups and classes called?
The arrangement of plants into different groups and sub-groups and classes is called classification. These are classified on the basis of similarities. The characters which are used as the basis of classification are called criteria of classification.
What class are similar orders in?
Similar orders form a class. For example, all the orders of flowering plants are placed in single class Angiospermae.
What is the taxonomic rank below species and subspecies?
The taxonomic rank below species and subspecies is variety. It will have an appearance distinct from other varieties. And they will hybridize freely.
