What are dead xylem and phloem cells of a woody plant called?
Dead xylem cells are called "tracheids" or "vessel elements," while dead phloem cells are called "sieve cells" or "sieve tube members."
Do birds have nucleated red blood cells?
Yes, birds have nucleated red blood cells.
What is the name of the tissue that contains seive tubes?
Parenchyma cells in "phloem tissue"
What is dead phloem called on a tree?
Dead phloem on a tree is called "inner bark" or "bast." It serves to transport nutrients within the tree but is no longer living tissue once it dies.
Do phloem cells contain chloroplasts?
No, phloem cells do not contain chloroplasts. Chloroplasts are typically found in plant cells that are involved in photosynthesis, such as leaf cells, while phloem cells are specialized for transporting nutrients, such as sugars, throughout the plant.
What are dead xylem and phloem cells of a woody plant called?
Dead xylem cells are called "tracheids" or "vessel elements," while dead phloem cells are called "sieve cells" or "sieve tube members."
Do birds have nucleated red blood cells?
Yes, birds have nucleated red blood cells.
Why are all living things composed of nucleated cells?
Not all are. Many biologists believe that bacteria are alive, and they do not have a nucleus. Also, though there is some debate, viruses are also sometimes considered alive, and not only do they not have a nucleus, they do not even have a plasma membrane. The definition of what is alive and what is not is quite complex and goes beyond nucleated cells called eucaryotes and non-nucleated cells called procaryotes.The red blood cells in your body are not nucleated.
Which structures make up phloem?
Phloem tissue consists of: conducting cells, generally called sieve elements; parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and supportive cells, such as fibres and sclereids.(attribution: wikipedia, Phloem)
A layer of cells that makes xylem and phloem is called?
CAMBIUM
New xylem and phloem cells are formed from a layer of cells called what?
vascular cambium
Are phloem cells alive?
Yes, Phloem cells are alive.
Does areolar or loose connective tissue lacks nucleated cells?
Areolar connective tissue contains various types of cells, including nucleated cells such as fibroblasts and immune cells. However, loose connective tissue is a broader term that encompasses various types of connective tissues, some of which may not contain nucleated cells. Examples of loose connective tissues without nucleated cells include adipose tissue (which primarily consists of fat cells) and cartilage.
What tissue in plants is made of specialized cells that transports nutrients from the leaves to other areas of the plant?
The tissue that transports nutrients from the leaves to other areas of the plant is called phloem. Phloem is made up of specialized cells called sieve tube elements and companion cells that work together to transport sugars, hormones, and other important molecules throughout the plant.
Are all white blood cells nucleated?
Yes, all white blood cells are nucleated, meaning they contain a nucleus. This nucleus plays a crucial role in the functions of white blood cells, such as producing antibodies and coordinating immune responses.
Sugars are conducted through plant tissue by the?
The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem. Part of the phloem is made of sieve tubes that permit the flow of sugars solution through the influence of fluid pressure differential. The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.
Does mitosis occur in the phloem?
No, mitosis does not occur in the phloem. Mitosis is the process of cell division, and in the phloem, specialized cells called sieve elements are responsible for transporting sugars. These sieve elements are formed via a process called differentiation, not mitosis.
