Document Summary
Cellular ingestion; engulfing food particles or foreign bodies by surrounding them with cytoplasm and forming a membrane-bound vesicle or vacuole containing the particle. Uptake of fluid, rather than particulate material, by endocytosis; surrounds the fluid with cytoplasm to form a vesicle or vacuole. (gr. pinein, to drink + kytos, cavity or cell) A form of asexual reproduction found in some protozoans. An already multinucleated cell undergoes cell division that results in each daughter cell containing only one of the many nuclei present in the parent cell. This is also referred to as multiple fission. (gr. schizein, to cleave or split + gone, birth) A form of asexual reproduction where the fusion product of the male and female gamete (the zygote) undergoes multiple cell divisions that produce sporozites. Found in animals in the protozoan phylum apicomplexa. (gr. sporos, seed + gonos, birth) A true body cavity that forms by schizocoelus splitting of the mesoderm.
