Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:
Plant stems can be Underground stem, Aerial stem, and subaerial stem due to its presence and strength of the stem. Underground stem are thick stems that run below the ground surface. e.g rhizome. Aerial stems are thin stems that can not stand erect. Examples include watermelon and strawberry etc. Subaerial stems are very thin stems that do not rise up but grow just above the ground. for example, water plantain, flowering rush etc.

<span>There are two physical differences
between Low pressure systems and </span>High pressure systems.
First, is the circulation surrounding
them.
Secondly, is the atmospheric motion
that they cause.
Low pressure systems circulate counter-clockwise. High pressure systems
circulate clockwise. These "motions" are the
building blocks in our atmosphere. They give us our weather.
A Low’s counter-clockwise circulation forces air upward (ultimately resulting in
condensation, cloud formation and ultimately precipitation). A High’s clockwise
circulation causes a sinking motion in the atmosphere, resulting in fair/clearer
and often sunnier skies.
