Image showing the location of the mouth, labelled mo, and the anterior sucker, as labelled sckr. The alimentary canal of F. hepatica has a single mouth which leads into the blind gut; it has no anus. The mouth is located within the anterior sucker on the ventral side of the fluke.
Plasmodium is a eukaryote but with unusual features. The genus Plasmodium consists of all eukaryotes in the phylum Apicomplexa that both undergo the asexual replication process of merogony inside host red blood cells and produce the crystalline pigment hemozoin as a byproduct of digesting host hemoglobin.

Within the Plasmodium clade lay the genera Hepatocystis, Nycteria and Polychromophilus. Plasmodium odocoiliei appeared to be very divergent in the clade. Within the palsmodium clade the reptile species formed one grouping while the subgenera Laverinia, Plasmodium and Vinkeia also formed subgroupings. These results if confirmed suggest that the ...
P. polycephalum plasmodium cultivating two "islands" of agar substrate overlying a glass coverslip. Physarum polycephalum growing from an oat flake (center) towards hairy roots of the plant Valeriana officinalis (left). Physarum polycephalum has been shown to exhibit characteristics similar to those seen in single-celled creatures and eusocial ...
Circumsporozoite protein (CSP) is required for host invasion. [4] Warburg et al., 1992 provides a monoclonal antibody against CSP and demonstrates efficacy. [4] The complete inhibition of sporozoite colonization of Aedes aegypti salivary glands they achieved could be due to the antibody itself blocking contact between the sporozoites and the gland surface, however the antibody's binding is ...
In this way the cell reaches a speed of up to 1000 μm per second – the speed in plant cells is 2–78 μm per second. [11] A resting state, the so-called sclerotium , may occur in this phase. The sclerotium is a hardened, resistant form composed of numerous "macrocysts", which enable the myxogastria to survive in adverse conditions, for ...
In Paramecium caudatum, the stages of conjugation are as follows (see diagram at right): Compatible mating strains meet and partly fuse; The micronuclei undergo meiosis, producing four haploid micronuclei per cell. Three of these micronuclei disintegrate. The fourth undergoes mitosis. The two cells exchange a micronucleus. The cells then separate.
