(of an immature or stem cell) capable of giving rise to several different cell types.
Energy stored in food can be used by cells to add a phosphate group to ADP to make ATP. This cycling of ATP to ADP occurs in a metabolic process called cellular respiration. phosphate group breaks, and energy is released. ATP becomes ADP, and the cycle of storing and releasing energy continues until the cell dies.
The answer is <span>D- thigmotropism
</span>
Tropism is plant growth in a response to a stimulus.
Through the process of elimination:
A - phototropism is plant growth in a response to light.
B - Photoperiodism is an organism reaction to the lengths of days and nights.
C - Gravitropism is plant growth in a response to gravity.
D - Thigmotropism is plant growth in a response to contact
Since <span>a grapevine makes a contact with a fence, this is an example of thigmotropism.</span>
