Water-storing plants and deeply rooted shrubs are plants that characterize?
Nady [450]

Desert vegetation or xerophytes includes bushes with deep roots and plants that store water.

Another name for desert plant:

A plant species known as a xerophyte has evolved to live in environments with little fluid water, like a desert or an area surrounded by ice or frost in the Mountains or the Polar regions. Cacti, pineapples, and various Gymnosperm species are a few well-known instances of xerophytes.

  • Xerophytes have different adaptations to their morphological characters (morphology) and basic physiological functions (physiology) that allow them to store significant amounts of water and save it during dry seasons. During prolonged periods of severe dehydration or evaporation of their organs, some creatures can live, and at those times, their biochemical function may cease. Xeromorphic flora has such biological and morphological modifications.

Ksju [112]
It is false that u<span>nlike third-world and developing nations, the u.s. has no incidence of hungry or malnourished people.
You can find hungry people anywhere - even in the richest countries in the world. Not everyone has the same opportunities and living conditions, so it is only normal that there will be poor people who cannot afford even food.</span>
