Alteration of generations means that the plant produces both haploid and diploid multicellular organism.
Explanation:
Alteration of generation is known as metagenesis,which can be seen in some plants and algae that have distinct haploid sexual and diploid asexual stages.
The multicellular haploid gametophyte contain 'n' chromosome which alternates with diploid sporophytes that are diploid containing 2n chromosomes.
Two gametes of same species fuse with together and produces diploid zygote that develops into diploid sporophytes.
This relationship that occur between sporophytes and gametophytes varies within different plant groups.
Scientists have yet to prove that the current global warming trend is not part of the natural cycle of Earth. Many things are being done now, mostly focusing on emission controls placed upon industry and transportation.
Chloroplasts are only found in the parts of the plant that are capable of photosynthesis. The majority of chloroplasts are found in the leaves of the plant because these structures have the greatest surface area for absorption. The outer part of a plant stem may also contain chloroplasts.
