This is a list of all the genera in the botanical family Arecaceae, the palm family, arranged by tribes and subtribes within the family. [1] Genera Palmarum (2008) lists 183 genera. [2] Lanonia, Saribus, and the monotypic genera Jailoloa, Wallaceodoxa, Manjekia, [3] and Sabinaria, which were described after 2008, have also been included below.

Subfamily Nypoideae contains only one species, Nypa fruticans, [19] which has large, pinnate leaves. The fruit is unusual in that it floats, and the stem is underground and dichotomously branched, also unusual in palms. The Phytelephantoideae is the sixth subfamily of Arecaceae in N.W. Uhl and J. Dransfield's 1987 classification. Members of ...

Secondary growth thickens the stem and roots, typically making them woody.Obstructions such as this metal post and stubs of limbs can be engulfed. In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems ...
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells will grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem will bend to the side of the slower growing cells as ...
In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA replication occurs) and is followed by telophase and cytokinesis; which divides the cytoplasm, organelles, and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.
Plant growth takes place in well defined plant locations. Specifically, the cell division and differentiation needed for growth occurs in specialized structures called meristems. [1] [2] These consist of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs ...
