Are egg cells specialized cells? –

Although an egg can produce every cell type in an adult organism, it is itself a highly specialized cell, uniquely equipped with the single function of generating new individuals. The cytoplasm of the egg can even reprogram the somatic nucleus so that the nucleus can direct the development of a new individual.

What are specialized cells?

Specialized cells are cells that have developed certain characteristics to perform specific functions. Example: red blood cells (rbcs). Function – When red blood cells bind to a protein called hemoglobin, it carries oxygen throughout the body.

How do cells become specialized?

cells undergo a process called differential gene expression. This process allows cells to become specialized because their structure determines their function. The process begins when stimulation acts on non-specialized cells (cells that have the potential to become any of the body’s pluripotent stem cells).

What is the main function of red blood cells?

Red blood cells are responsible transport oxygen from the lungs to body tissues. Your tissues use oxygen to produce energy and release a waste product called carbon dioxide. Your red blood cells carry carbon dioxide waste to your lungs for you to exhale.
