A survey of flora in the garden infront of admin block of Punjab university was conducted for plant diversity during period of December,2012 to January,2013.All the plants were enlisted and photographed. The information about their general description, habitat, mode of propagation, reproduction and economical uses was searched, collected and discussed.
Introduction:
Plant diversity refers to the variety of plants that exist in this world. (Henry,2005)Plants are fundamental to life providing basic and immediate needs of humans for food and shelter and acting as an essential component of biosphere maintaining life on planet. All modern terrestrial plants are the descendants of algae that adapted to a terrestrial habitat roughly 500 million years ago. Compared to water,land is an erratic habitat where temperature and moisture availability may change abruptly and dramatically.
There are four major groups that evolved in the following sequence: 1. Bryophytes; which include the mosses
2. Seedless vascular plants; which include the ferns
3. Gymnosperms; many of which are also called conifers
4. Angiosperms; the ‘flowering’ plants, which now predominate. Diversity within a population of plants of the same species may be considered a primary level of variation. The factors determining diversity within species are also being better defined by use of DNA analysis method. Plants and plant diversity contribute directly and indirectly to the enrichment of life experiences for humans. The role of plants in the food chain is dominant for all animal life. Plant diversity is a key contributor to environmental sustainability on a global scale. Studies of
