The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment. during the past two decade, the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants, provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants. three new plant based epochs have been recognized. on the other hand, molecular sequence studies have provided insights into the phylogeny and early branches of land plants. a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences. this paper summarizes recent advances and new knowledges, comments on the phylogenetic studies based on the cladistic analysis
陸生植物的起源和演化是地球生命中的重大事件，它影響到地球上所有的其他生命和全球環境。在過去的20年中，從中奧陶世歷經整個志留紀至早泥盆世的巖層中，化石植物微化石和大化石的新發現改變了人們對陸生植物起源的認識，並且為陸生植物和維管植物早期演化分異提供了基部類群分化的時間框架。據此人們識別出地史中的3個陸生植物的時代：始胚植物時代始維管植物時代和真維管植物時代。The ultrastructure of the merozoites of eimeria tenellawas observed and discribed. the pellicle consist of two layer membranes, the outer membrane was a continous covering enclosing the whole merozoites, while the inner pellicular complex is interrupted at the anterior and the micropore, and thicken to form the polar ring and micropore. there are 24 microtubules under the pellicle of the merozoite which originated from the polar ring, all of them are connected with the polar ring, and extend alongside the inner pellicular complex to the middle of the merozoite. the head of the merozoite consists of a conoid, an apical vesicule and polar ring. the conoid is a hollow truncated cone. the conoid and spical vesicule can stretch and contract. there are three or more rhoptry and a lot of micronemes. the nucleus has nucleolus. and two layer membranes
