Why does a mature mammalian red blood cell have no nucleus or organelles?

The red blood cell is really just a package of hemoglobin, which does not require any kind of metabolic process to perform its function. The absorption and release of oxygen by hemoglobin is spontaneous, it does not have to be driven by any other chemical process. This is quite unlike other cells which have functions that require some kind of biochemical activity that would be directed by the genetics of the cell nucleus and assisted by organelles such as mitochondria etc. Muscle cells need these things to be able to contract or relax. Nerve cells need these things to be able to transmit or receive nerve signals. But red blood cells perform their function automatically, due to the chemical properties of hemoglobin.

∙ 13y agoThe primary function of the red blood cell is to transport oxygen and remove waste materials from organs.
The presence of a nucleus and other organelles would drain the cell of all its metabolic energy and make it a less efficient oxygen transporter. Also, red blood cells lose the nucleus and reduce in size during the maturation phase. Their reduced size allows them to go through very thin capillaries and reach every cell of the body

∙ 11y agoRed Blood Cells do not contain a nucleus (and therefore cannot replicate or live past 120days) because their function is to carry oxygen within their heme group, which occupies the space normally taken up by a nucleus. The erythrocyte is the mature red blood cell btw

∙ 13y agoIt's not just a matured red blood cell, all red blood cells don't undergo mitosis, because they don't have nucleus or DNA.

It makes them much empty.this allows much space to carry oxygen
Wiki User
∙ 12y agoBecause the main job of a red blood cell is to carry oxygen around the body. It has no nucleus or organelles so it can carry as much oxygen as possible.

A mature red blood cell cannot reproduce because it lacks?
Cell organelles such as nucleus,centioles are absent annd hence cant reproduce.
Does an animal cell have a nucleus?
Yes, all animal cells (except for mature mammalian red blood cells) contain a nucleus.Mammalian red blood cells have a nucleus initially, but do not have one once mature.yesyea ONLY animal cells have nucleus. plant cells are the kind that dont. learned that in fifth grade.
Does a red blood cell have organelles?
No. They do not. They are able to support themselves without organelles helping. They are degraded in the bone marrow so that there is more space for the hemoglobin.
Does an animal cell has nucleus and organelles?
No -animal cells do not have a cell wall, they have a cell membrane.Yes - animal cells have a nucleus (with a few exceptions such as the Red Blood Cell).
Can a mature red blood cell divide?
No, it cannot divide since mature red blood cells have no nucleus. there are no chromosomes to replicate.
What mammalian cell doesn't have a nucleus?
Mature red blood cells do not have nuclei.
What do red blood cells not have?
Mature red blood cells do not have a nucleus nor organelles.
Which type of blood cell has no nucleus?
That depends on which species you're referring to. In most mammals, including humans, mature red blood cells do not have a nucleus.
What cell doesn't contain a nucleus and organelles?
A prokaryote aka a bacterium doesn't contain a nucleus but it does contain small ribosomes.
What does a mature red blood cell not have?
nucleus i thinkNucleusThere are, in fact, several Organelles that are missing from a red blood cell (Erythrocyte), but the most significant one is the nucleus.DNA
Do a mammalian cellular organelle contain a nucleus?
Mammalian cells have nuclei. But red blood cells lack
What components of mammalian blood contains a nucleus?
White Blood Cells (Leukocytes)
A mature red blood cell cannot reproduce because it lacks?

Does an animal cell have a nucleus and oranelles?
Most do, some don't. A mammalian red blood cell lacks a nucleus.
Do animals have cell nucleus?
Yes, animal cells have a nucleus (except for mammalian red blood cells).
Does a nucleus lack mature red blood cells?
It is actually the other way around - mature red blood cells lack a nucleus.
