6 Questions
Which of the following is a characteristic feature of bryophytes?
Dominant gametophyte generation
Which of the following is a defining feature of gymnosperms?
Cones for reproduction
What is a distinguishing characteristic of pteridophytes?
Reproduction by spores
Explain the concept of alternation of generations in the context of plant kingdom.
The alternation of generations refers to the life cycle of plants where there is a distinct multicellular haploid and diploid phase. In this life cycle, the haploid phase (gametophyte) and the diploid phase (sporophyte) alternate generations.
Discuss the significance of heterospory in the evolution of plant kingdom.
Heterospory, the production of two types of spores (microspores and megaspores), contributed to the evolution of seed plants. This innovation allowed for the development of pollen grains and seeds, which provided advantages for reproduction and dispersal in diverse environments.
Examine the role of plant kingdom in the ecological balance of the environment.
The plant kingdom plays a crucial role in maintaining ecological balance by contributing to oxygen production, carbon dioxide absorption, soil stabilization, and providing habitats and food for various organisms. Additionally, plants are essential for the functioning of ecosystems and nutrient cycling.
