Question

Francine bought her mother some cut flowers for mother's birthday. She placed the flowers in a vase of water. A week later, Francine pointed out to her mother that the flowers were still living. She also told her mother that this fact proved something about plants. What did Francine tell her mother?

Answer 1

Francine's observation shows that plants can continue to absorb water through their stems, allowing them to live even after they've been cut from their root systems. This process, known as capillary action, is a key concept in biology and plant science.

Step-by-step explanation:

Francine's observation that the cut flowers are still alive after a week in a vase of water demonstrates a key concept in biology - specifically, plant science. When she tells her mother this, it is likely that she is referring to the fact plants can continue to absorb water through their stem - a process known as capillary action. This is because a plant's stem has tiny tubes known as xylem, which transport water from its roots (in this case, the bottom of the stem) up to the rest of the plant. This allows it to remain hydrated and alive, even when disconnected from its original root system.
