Undifferentiated actively dividing tissues, often referred to as meristematic tissues in plants or stem cells in animals, consist of cells that have not yet specialized for specific functions. These tissues are characterized by their ability to proliferate rapidly, allowing for growth and regeneration. In plants, meristematic tissues are found in areas like the tips of roots and shoots, while in animals, stem cells can be found in bone marrow and other tissues. Their capacity for division and potential to differentiate into various cell types is crucial for development and healing.
What else can I help you with?
Are undifferentiated cells found in meristematic tissue?
Yes, undifferentiated cells are found in meristematic tissue. Meristematic tissue is responsible for plant growth and contains actively dividing cells that have the ability to differentiate into various types of plant tissues.
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.
Where does mitosis actively take place in plant cell?
Mitosis actively takes place in the meristematic tissues of plants, which are regions of undifferentiated cells. These tissues are primarily found at the tips of roots and shoots (apical meristems) and in the vascular cambium and cork cambium (lateral meristems). Mitosis allows for growth and the production of new cells, contributing to the plant's overall development and tissue regeneration.
What does meristematic zone mean?
The meristematic zone is a region in plants where actively dividing cells are located, responsible for plant growth and development. These cells have the ability to differentiate into various types of plant tissues.
Plant meristems produce new cells by which of these processes?
Plant meristems produce new cells through cell division. The cells in the meristem divide actively, allowing for growth and development in plants. This process is essential for maintaining and replenishing the pool of undifferentiated cells in plant tissues.
Are undifferentiated cells found in meristematic tissue?
Yes, undifferentiated cells are found in meristematic tissue. Meristematic tissue is responsible for plant growth and contains actively dividing cells that have the ability to differentiate into various types of plant tissues.

What is the embryonic connective tissues?
Undifferentiated mesenchymal tissue
How do cells in a meristem differ from cells in other types of plant tissue?
Cells in and around the meristems are the only ones that divide. Once the cell has been pushed past the meristematic zone, it stops dividing. Meristematic cells are also undifferentiated, they have not yet developed specializations such as vascular or dermal tissue.
What does meristematic zone mean?
The meristematic zone is a region in plants where actively dividing cells are located, responsible for plant growth and development. These cells have the ability to differentiate into various types of plant tissues.
Plant meristems produce new cells by which of these processes?
Plant meristems produce new cells through cell division. The cells in the meristem divide actively, allowing for growth and development in plants. This process is essential for maintaining and replenishing the pool of undifferentiated cells in plant tissues.
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'.
All undifferentiated lymphocytes are produced in which one of the organs?
Undifferentiated lymphocytes are produced in the bone marrow. They then migrate to the thymus or other lymphoid tissues to mature and differentiate into T cells, B cells, or natural killer 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 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 does the stem 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
What does cambium do for the stem?
