Red blood cells have no nucleus after they have fully developed. The nucleus is ejected so that there is more room for hemoglobin. That molecule is what carries oxygen.
Because there is no nucleus the cell can not repair itself and will die in about 120 days. It's parts will then be recycled.
Red blood cells are the only functional cell with no nucleus
Yes, nuclei can be visible in trichome cells. Trichomes are specialized outgrowths on plant surfaces, and they often contain cellular structures, including a nucleus, which is essential for their metabolic functions. The visibility of nuclei in trichome cells can depend on the specific type of trichome and the method of observation, such as microscopy techniques.
1) Frog's red blood cells contain a nucleus that carries all the genetic information needed to make new cells by replication. Human red blood cells contain no nuclei because they reproduce differently than frog. 2) We human have platelets in our blood but frogs do not have them.
Nuclei can vary in size depending on the type of cell. Generally, the nuclei of cells within the same species are similar in size, but there can be variations between different types of cells. Some cells, like muscle cells and some liver cells, may have multiple nuclei.
Most brain cells, or neurons, typically have one nucleus per cell. However, glial cells, which support and protect neurons, can have multiple nuclei, depending on their type and function. Overall, the majority of brain cells contain a single nucleus, essential for managing cellular functions and genetic material.

No, nuclei in cells are not all the same size. Nuclei can vary in size depending on the type of cell and its function.
Organisms made of cells that contain nuclei are classified as eukaryotes. Eukaryotic cells have a well-defined nucleus that houses their genetic material within a membrane-bound organelle. Examples of eukaryotic organisms include animals, plants, fungi, and protists.

All other cells in the human body are the only type that are prokaryotic, meaning that they do not contain a nucleus, the control center of the cell.

Cells that do not contain a "true" nucleus are called prokaryotes. Sometimes eukaryotic cells are anucleate(no nucleus) when mature. Erythrocytes (red blood cells) in mammals are an example of eukaryotic cells that do not contain a nucleus when mature.
The cells of eukaryotes will contain a nucleus.
