To determine where actively dividing cells can be found, we need to understand the types of tissues and regions in a plant where cell division takes place.
1. Meristems: Meristems are regions in plants where active cell division occurs. There are two main types of meristems: apical meristems and lateral meristems. Apical meristems are found at the tips of stems and roots, whereas lateral meristems are located in the cambium layer, which is responsible for the growth in thickness of plant stems and roots.
2. Xylem tissue: Xylem tissue is responsible for transporting water and nutrients from the roots to other parts of the plant. Mature xylem cells are dead and do not undergo cell division. However, the cambium, which is a type of lateral meristem, can produce new xylem cells by cell division.
3. Epidermal tissue: The epidermis is the outermost layer of cells in plants, providing protection and acting as a barrier. The epidermal tissue usually consists of a single layer of cells and is not actively undergoing cell division. However, during periods of growth or when damage occurs, cell division can take place in the epidermis to repair or replace damaged cells.
4. Center of stems: The center of stems generally consists of pith and vascular tissues, such as xylem and phloem. While primary growth occurs at the apical meristem and secondary growth at the cambium, the center of stems is not typically a site of active cell division.
5. Phloem tissue: Phloem tissue is responsible for transporting organic nutrients, such as sugars, from the leaves to other parts of the plant. Like xylem, mature phloem cells are also non-dividing. However, the cambium can give rise to new phloem cells through cell division.
Based on this information, the location where actively dividing cells can be found is primarily in meristems, specifically apical meristems at the tips of stems and roots, and lateral meristems (cambium) responsible for secondary growth.
