The least mature type of spermatogenic cell is the spermatogonium. Spermatogonia are the stem cells located in the seminiferous tubules of the testes, responsible for undergoing mitosis to produce more spermatogonia or differentiate into primary spermatocytes. They represent the earliest stage in the process of spermatogenesis, which ultimately leads to the formation of mature sperm cells.
The mature red blood cell lacks a nucleus, and so is unable to reproduce.
A red blood cell, also known as an erythrocyte, is an example of a cell type without a membrane-bound nucleus. These cells lose their nucleus as they mature to make room for hemoglobin, the oxygen-carrying protein they contain.
In a mature plant cell, the vacuole can occupy up to 80-90% of the cell's volume. This large vacuole is crucial for maintaining turgor pressure, storing nutrients and waste products, and contributing to the overall structure and stability of the plant. Its size can vary depending on the type of plant and its developmental stage.
Immunoglobulins, more commonly referred to as antibodies.- Immunoglobulins/antibodies are synthesized by plasma cells which is a specialized type of B-cell. Immature B-cells are produced in red bone marrow and then migrating to the spleen where some of them mature to a mature B-cell. A mature B-cell can differentiate into either a memory B-cell or a plasma cell."- In human adults, Immunoglobulins are synthesized by plasma cells (specialized type of B-cell) which in turn originates from red bone marrow in large bones (eg. femur).
One example of a cell type that may spend decades in interphase without dividing is a neuron. Neurons are specialized cells in the nervous system that transmit electrical signals. Once neurons mature, they usually remain in a non-dividing state for the remainder of an individual's lifespan.
The cell's final position in an emerging organ determines what kind of cell it will become
Mature red blood cells are considered the least sensitive to ionizing radiation because they lack a nucleus and do not undergo cellular division, making them less susceptible to DNA damage caused by radiation.
The mature red blood cell lacks a nucleus, and so is unable to reproduce.

monocytes ( a type of defensive white blood cell or leucocyte) are immature when they leave the blood vessels but mature and develop rapidly into active cells called macrophages.
Neutrophils and eosinophils descend from myeloblasts, which are a type of precursor cell for granulocytes in the bone marrow. These mature blood cells are part of the innate immune system and play key roles in fighting infections and regulating inflammation.
