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
利用透射電鏡對柔嫩艾美耳球蟲裂殖子的超微結構進行了觀察描述.柔嫩艾美耳球蟲裂殖子的表膜由外膜和內膜復合體兩層組成,外膜連續,內膜復合體在頭部斷開形成極環,在其它部位斷開形成微
孔;裂殖子的膜下微管24根,起始於極環,向後延伸至細
胞核處;裂殖子的頭部由頂泡、錐體和極環組成,錐體和頂泡可以伸縮;柔嫩艾美耳球蟲裂殖子棒狀體3個以上,微線數量很多,二者都由電子緻密的結構組成;細
胞核位於裂殖子的中後部,外被雙層膜,有電子緻密的核仁和染色質

There are many adaptive changes in the two research subjects ( artemisia. songarica schrenk. and seriphidium. santolinum ( schrenk ) polijak. ) in morphology and anatomy, such as with the increase of the daily age, the root - shoots ratio increased ; the root became stronger ; the ratio of leaf volume and leaf area increased ; the volume of epidermic cell decreased ; the cut - icle and phellem layer on the surface of root thickened. stoma caved in leaf ; epidermal hair of leaf and stem well - developed, palisde tissue developed well, the cell gap decreased ; the spongy tissue disappeared ; leaf is kinds of isolateralthat is the typical xeromorphic structure ; crystal cell and fibric cell increased ; conducting tissue and mechanical tissue developed well ; bundle sheath appeared
