As water evaporates and is absorbed by plants, the water content gradually declines until plants can no longer extract the remaining water held by soil particles. This stage is known as which of the following?
Water-holding capacity
O Field capacity
O Wilting point
O Desiccation

Wilting point

Explanation:

Wilting point is defined as the minimum amount of water in the soil that the plant requires not to wilt. If the soil water content decreases to this or any lower point a plant wilts and can no longer recover its turgidity when placed in a saturated atmosphere for 12 hours.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
