Red blood cells are the only functional cell with no nucleus
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
Smooth muscle tissue has a single nucleus in each cell :)
The type of muscle tissue that have only one or two nuclei per cell are cardiac muscle cells. Their nuclei are located in the center of a cell.

Smooth Muscle Tissue
tissues are made of specialized cells that do have nuclei
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
Adipose tissue
Skeletal muscle tissue.
Smooth muscle tissue has a single nucleus in each cell :)
The type of muscle tissue that have only one or two nuclei per cell are cardiac muscle cells. Their nuclei are located in the center of a cell.
If it is spindle shaped, it is smooth (visceral) muscle tissue. If it is H or Y-shaped then it is cardiac muscle tissue. And, if it is rod shaped and has multiple nuclei, then it is skeletal muscle tissue. Another characteristic of both cardiac and muscle tissue is that it is striated with darker and lighter bands.

the dominant allele is in all egg nuclei.
the recessive allele is in all sperm nuclei.
