Artificial insemination allows the use of superior bull semen to improve cattle genetics widely. Multiple Ovulation Embryo Transfer (MOET) is a technique used in cattle and other mammals to increase herd improvement rates, not in poultry (which uses hatching eggs).

Explanation:
Plastids (chloroplasts, chromoplasts, leucoplasts) are unique to plant cells and some protists. They are involved in photosynthesis, storage, and imparting color. Mitochondria, Golgi apparatus, and ribosomes are present in both plant and animal cells. The cell wall and large central vacuole are also distinguishing features of plant cells.
