xylem

Depending on the type of plant, xylem tissue can be made up of one or two different types of cells. Plants like ferns and conifers have xylem “straws” that are made of slender cells called tracheids. At maturity these cells die, leaving behind a rigid cell wall scaffolding tube to conduct water and minerals.

Specialised cells in animals and plants

These are some specialised cells in plants that you should know:

• Palisade Cell.
• Spongy Mesophyll Cell.
• Guard Cell.
• Xylem Cell.
• Phloem Cell.
• Root Hair Cell.

Nerve cells, blood cells, and reproductive cells are examples of specialized cells. Nerve cells, called neurons, have long connections that help them transmit messages throughout our nervous system.

A specialised cell is when a cell has certain features that make it very good at its job. Cell differentiation: These cells were stem cells. …

Sperm cells are specialised because they have a specific function in the body- to fertilise the female gamete (egg). Therefore to carry out its job, it has special features typical body cells do not. The nucleus, which contains the genetic material is located in the head of the sperm cell.

Sperm Cells are specialised in a number of ways. They have an Undulipodium (tail) which moves by energy generated by many mitochondria and propels the cell. The head of the cell contains an Acrosome, which is a specialised Lysosome that releases enzymes so that the Sperm Cell can penetrate the Ovum Coat of the Egg.

Explanation: A specialized cell has a unique and important structure to perform a special job e.g. root hair cell has a long protrusion for more absorption of water and minerals (like magnesium and nitrate ions). Non specialized cells contain the basic organelles for performing normal tasks. An example is stem cells.

Human embryonic stem cells are considered to be immortal: they do not age, they can proliferate indefinitely, and form any tissue of the organism.

HeLa cells, these researchers claim, are no longer human at all: they are single-celled microbes–closely related to us, to be sure, but their own distinct species. HeLa cells are not connected in any way to people, explains evolutionary biologist Leigh Van Valen of the University of Chicago.

1- HeLa cells are cancerous. 2- HeLa cells grow unusually fast, even considering their cancerous state. Indeed, HeLa cells grow easily and rapidly, doubling cellular count in only 24 hours, making them ideal for large scale testing. They grow so fast that they can contaminate and overtake other cell cultures.

Embryonic stem cells

So, if you plan on making your stem cells healthy and make your body boost its production, then these are the top 3 supplements that you need to consider: Spirulina. Quercetin….Astragalus Membraneceus (Root)

• It can protect healthy stem cells by improve apoptosis.
• It contains more than 63 differently flavonoids.

Stay Active, Exercise, and Lift Weights Studies have shown that older animals that are more active have better quality stem cells that create more bone. This research also shows that stem cells in muscles are increased by exercise and lifting heavy weights. The key is consistent activity.

Here are 10 healing foods that can help your body recover.

1. Leafy green vegetables.
2. Eggs.
3. Salmon.
4. Berries.
5. Nuts and seeds.
6. Poultry.
7. Organ meats.
8. Cruciferous vegetables.

Vitamin B1 (Thiamine or Thiamin) Vitamin B1, or thiamine, is a vitamin that the body requires for energy metabolism and for cell growth, function, and development.

Federal funding for human embryonic stem cell research is illegal, unethical, and unnecessary. Unethical: Destroying living human embryos for research violates the basic tenet of the healing arts: “first do no harm.” It is ethically wrong to harm or destroy some human beings for the potential benefit of others.
