Binary fission

A form of asexual reproduction in protozoans such as Paramecium caudatum where a cell divides into two daughter cells.

Conjugation

A form of sexual reproduction and genetic exchange in protozoans such as Paramecium caudatum.

Dissecting microscope

A microscope used for low-magnification observation of specimens, featuring components such as ocular eyepieces, focus control, focus arm, stage plate, upper illumination, and lower/top illumination controls.

Compound microscope

A high-magnification microscope featuring ocular lenses, an inclined binocular tube, revolving nosepiece with objectives, stage, condenser, iris diaphragm lever, in-base illuminator, and coarse/fine adjustment knobs.

Euglena anatomy

Anatomical features of Euglena including the nucleus, chloroplasts, stigma (eyespot), flagellum, flagellar pocket, cell membrane, and paramylum grains.

Trypanosoma blood smear anatomy

Microscopic appearance of Trypanosoma in a blood smear showing the parasite with its undulating membrane, parabasal body, and surrounding red and white blood cells.

Amoeba proteus anatomy

Anatomical features of Amoeba proteus including pseudopodia, plasmagel (ectoplasm), plasmasol (endoplasm), nucleus, cell membrane, food vacuoles, and a contractile vacuole.

Paramecium caudatum anatomy

Anatomical features of Paramecium caudatum including cilia, macronucleus, micronucleus, oral groove, cytostome, cytopharynx, pellicle, trichocysts, food vacuoles, and contractile vacuoles with radiating canals.

Paramecium binary fission identification
