IPA: /ˈʌp.teɪk/
KK: /ˈʌpˌteɪk/
The process of taking in or absorbing something, especially by a living organism.
The plant's uptake of water is essential for its growth.
Uptake → It is formed from "up" (meaning higher or in an upward direction) and "take" (from Old English "tacan", meaning to seize or grasp). The word "uptake" refers to the act of taking in or absorbing something, often in a higher or more elevated sense.
Think of 'taking' something ('take') and doing it in an 'upward' direction ('up') — that's why uptake means to absorb or take in.
