When Cheng Tinglu returned home with a pot of mimosas in his arms, Lu Wansheng Su Tang and Shen Mobei were eating the cake that Qiao Anxia had just taken the exam in the living room of the Cheng family.

Seeing that Su Tang was fine, when he saw Shen Mobei, he obviously couldn't help but flash a touch of disgust on his face.

Why is this kid here again?

"Brother Xiaolu, are you back?" Seeing him come back, Lu Wansheng's eyes lit up, and she immediately ran towards the other party happily.

"Yours!" Cheng Tinglu handed her the plant in his hand.

"What is this?" Lu Wansheng asked with wide eyes of curiosity.

Cheng Tinglu: "The boss said this is a mimosa!" ”

As soon as he heard this name, he thought of Shengsheng girl, isn't this girl easily shy?

"This is a mimosa! Is it true that if you touch it with your fingers, its leaves will come together? Su Tang couldn't help but leaned over and stared curiously at the mimosa in Lu Wansheng's hand.

Lu Wansheng heard about it for the first time, and curiously stretched out her finger and touched it.

The two little girls stared at the ...... without blinking with their big round eyes After half a ring, the little girl blinked, looked up at Cheng Tinglu, and her big watery eyes seemed to ask: Huh? How do its leaves not fit together?

Where does Cheng Tinglu understand this, in his eyes, all flowers and plants look the same, seeing Lu Wansheng looking at himself with big watery eyes, he thought about it, and then replied seriously: "Maybe this pot is more shameless?" ”

Lu Wansheng: ......

Cyonatose: ......

"What nonsense?"

Qiao Anxia walked over with the freshly squeezed juice in her hand, and slapped Cheng Tinglu's head, "They all tell you to read more often." ”

"Mother Joe, do you know why?" Lu Wansheng immediately turned to Qiao Anxia and asked.

Qiao Anxia put the juice on the table, pointed to the pot of mimosa in Lu Wansheng's hand, and explained with a smile: "Actually, there is a special structure under each small leaf of the mimosa and the bottom of the petiole, called the leaf pillow. There are a lot of parenchyma cells in this leaf pillow. To use our hands as an analogy, the two hands are fists facing each other, the arms are equivalent to the leaves, the fists are equivalent to the parenchyma cells, and the opposite fist is filled with cell sap, which is very strong, and the leaves are solid, once stimulated by the outside world, the cell sap runs out, and then it is soft, and the leaves cannot hold up. Later, when the cell sap slowly flows back into the cells, the leaves are stretched open again. ”

"It works on the basis of the self-protection of the plant. Do not allow a large number of water droplets to stay on the plant body, as it will be easily blown down by the wind. Therefore, when being touched or there are water droplets, the leaf pillow part that is sensitive to touch will quickly discharge the cell fluid, so that the leaf droops, if you often touch the mimosa, the water in the leaf pillow is gone, and when the new water is too late to replenish, the leaf does not move. At this time, just give him water! ”

"Mother Joe, you're amazing!" The little ones listened with relish, and looked at her with adoration in their eyes.

"Then let's water it." Su Tang urged eagerly.

"Don't worry, listen to me first."

Joan Xia continued with a smile, "Although many people like to raise mimosa, in fact, mimosa is slightly toxic, and long-term close contact will make the hair yellow and fall out, so it is best not to touch it when raising mimosa at home." Otherwise, it will be easy for our hair and eyebrows to fall out! ”
