Red blood cells do not have nuclei or mitochondria.
Mitochondria???
Cells that have nuclei are eukaryotic.
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.
Yes, mitochondria exist in animal cells.
Mitochondria is suspected to have been a unicellular organism that invaded cells. All cells have DNA. The mitochondria then stayed in the cells which explains why there are mitochondria in cells now.
Yes, Mitochondria are organelles inside of Cells, which contain Nuclei.
prokaryotes
Mitochondria???
They are prokariyotic cells.Also erithrocytes and seive tube elements do not have.
They don't have organelles such as nuclei, mitochondria or chloroplasts.
Nuclei and mitochondria have a membrane surrounding them. They are both organelles in the cell.
Nucleus Mitochondria
Not all cells have nuclei. All eukaryotic cells have nuclei and all prokaryotic cells do not.
they have 2 in each cell
Most eukaryotic cells -- those that contain nuclei -- also contain mitochondria, but there are exceptions to this rule. Some parasitic protists take energy from their hosts and do not have mitochondria. In humans, mature red blood cells lack mitochondria nor do they have any organelles. The RBCs die after 120 days because of this. They can't make energy.
all cells have a nuclei
Both are living organisms.
