No. Mammalian red blood cells do not have nuclei.
Mammalian cells have nuclei. But red blood cells lack
Not all cells have nuclei. All eukaryotic cells have nuclei and all prokaryotic cells do not.
all cells have a nuclei
No, nuclei in cells are not all the same size. Nuclei can vary in size depending on the type of cell and its function.
Nucleus is an imp component of cell essential for survival . An organised nucleus appears in eukaryotes(except mammalian rbc and sieve tube cells of phloem) for the first time .Prokaryotes have an unorganised nucleus....
Any and all eukaryotic cells have nuclei and membrane-bound organelles.
Mature red blood cells do not have nuclei.
Reptile red blood cells are nucleated, meaning they contain a nucleus, unlike mammalian red blood cells which are anucleate. Reptile red blood cells are also oval-shaped whereas mammalian red blood cells are typically circular. Additionally, reptile red blood cells contain different types of hemoglobin compared to mammals.
No, not all animals have nuclei. While most animals are made up of eukaryotic cells that contain nuclei, some simpler organisms, like certain types of parasites, can have variations in their cellular structures. Additionally, prokaryotic organisms, such as bacteria, do not have nuclei at all. However, all multicellular animals are composed of eukaryotic cells, which do contain nuclei.
The three structures found in all mammalian cells are the cell membrane, cytoplasm, and genetic material (DNA). These structures play essential roles in maintaining cell function, structure, and genetic information across all mammalian species.
Eukarya
Virtually all eukaryotic (meaning all plants, animals, funghi, etc) cells have nuclei. The only exception of which I can think are erythrocytes (red blood cells) which lose their nuclei as they mature in mammals.
