Question:

The ground tissue system is constituted by all of these, except

Options:

1. Medullary rays
2. Pericycle
3. Mesophyll
4. Xylem

Solution:

The ground tissue system is one of the three basic tissue systems in plants, which is responsible for various functions such as photosynthesis, storage, and support. The ground tissue system includes various cell types such as parenchyma, collenchyma, and sclerenchyma cells. Medullary rays are parenchyma cells that extend from the pith to the cortex of the stem and facilitate radial transport of water and nutrients. Mesophyll cells are specialized parenchyma cells that carry out photosynthesis in leaves. Pericycle is a layer of cells located just inside the endodermis, which gives rise to lateral roots in dicot plants. Xylem, on the other hand, is a complex tissue that transports water and dissolved minerals from roots to shoots.
