What is a meristem tissues?
It consists of undifferentiated cells in a plant, which form other tissues and, among other things, allow the plant to grow. They are analogous to "stem cells" in animals, which form various types of cells.
What is the structure of propagative roots?
Propagative roots have plenty of reserve food and actively dividing meristems separated by permanent tissues. When broken into pieces, each piece develop into a separate plant using totipotency of plant cells.
What statement regarding stem cells is false a. they form totipotent embryo b. can be induced to form tissues c. they are undifferentiated?
dsad
What is the plant root system made of?
The plant root system is made of various regions of tissues. These are root cap at the apex, the meristem of actively dividing cells, root hair zone and cell elongation and maturation zone having vascular tissue etc.
What plant cell is free to differentiate into various kinds of cells?
Meristem cells are undifferentiated cells that can develop into groud, vascular & dermal tissues depending on their location within the plant. In theory most cells can reproduce a full plant through a process known as totipotancy

What is the embryonic connective tissues?
Undifferentiated mesenchymal tissue
What is the function of the cambium?
The cambium is the layer of actively dividing cells between the xylem and phloem tissues of plants. It is responsible for the secondary growth of plants.

What does cambium do for the stem?
Cambium, in plants can be defined as layers of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots. Secondary growth can be defined as occurring after the first season and results in increase in thickness

Perpetually young tissues where cells retain the ability to divide are?
Meristematic. "A meristem is a tissue in all plants consisting of undifferentiated cells (meristematic cells) and found in zones of the plant where growth can take place." - Wiki entry on Meristem. The are not undifferentiated. This is what the question means by 'perpetually young'.
Why does irinotecan increase risk for diarrhea and neutropenia?
Irinotecan targets actively dividing cells in your body. In cases of cancer, this is a good thing because it stops rapidly dividing cancer cells from growing. However, it can also affect other tissues of your body that have high turnover rate, including the bone marrow and epithelial lining of the intestine. Hence, irinotecan increases the risk of diarrhea and neutropenia.
What are 5 examples of tissue?
Four adult primary types of tissues form the "fabric" of the human organism:1.epithelial tissues (covering/lining);2.connective tissues (support);3.muscle tissues (movement);4.nervous tissues (control).Plus: mesenchymal connective tissue, a type of undifferentiated loose connective tissue.
Cell types are most sensitive to radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
