Question:

Primary xylem is of two types, they are-

Options:

1. Protoxylem and metaxylem
2. Xylem parenchyma and xylem fibres
3. Tracheids and vessels
4. Simple xylem and complex xylem

Solution:

Primary xylem, which is the first-formed xylem tissue in developing plant organs, is composed of two types: protoxylem and metaxylem. Protoxylem refers to the early-formed xylem elements that are characterized by smaller cells with relatively thinner cell walls and smaller lumens. Metaxylem, on the other hand, refers to the later-formed xylem elements that are characterized by larger cells with thicker cell walls and larger lumens. Protoxylem and metaxylem can be distinguished based on their cell wall characteristics, such as the presence of annular, spiral, or reticulate thickenings, and their developmental timing during plant growth.
