The figures of four people and one dog are condensed in a botanical garden.

The environment here shows that it is autumn, and there are many large and small greenhouses and greenhouses in the botanical garden, and Zhu Lang and the four of them are in a greenhouse, which is full of tomatoes.

Kiki screamed, "So many big and red tomatoes!" Such a maturity. ”

Yanyan looked around and observed for a while before asking, "How do you know?" ”

Binbin always paid attention to the two beautiful girls, and when he saw that the opportunity had come, he hurriedly stepped forward to explain: "I checked the information in this regard. Tomatoes are divided into red, pink, orange-red and yellow according to the color of the peel according to different varieties; According to the shape of the fruit, it can be divided into round, oblate, oblong, and pointed. When choosing tomatoes, choose one that is pink in color, round in color, and has small white dots on the skin, and feels like a faint layer of powder on the surface, and it is very soft to pinch. The pedicle must be rounded, preferably with a light cyan. The kernels are earthy yellow, and the flesh is red, sandy, and juicy. Don't buy tomatoes with pointed, high bottoms, angular or irregular shapes, and don't pick tomatoes that feel light to hold, these are ripe tomatoes. The ripe tomatoes are all red, very hard to the touch, polyhedral in appearance, and the seeds are green or ungrown when you break them open, and there is no juice in the pulp. This is a method used by traders to ripen bananas, coating tomatoes with a chemical drug called 'ethephon', which is less toxic but harmful to the human body if consumed for a long time. ”

"You know so much!" The two girls exclaimed in unison.

Bin Bin glanced at Zhu Lang and pretended to be mysterious: "Do you know the origin of tomatoes?" ”

Yanyan was surprised again: "I know, tomatoes are also called tomatoes, but they are all over the world, what else does it come from?" ”

Binbin felt that Zhu Lang couldn't answer, so he put on a posture and spoke slowly-

"Tomatoes, also known as tomatoes and persimmons, are rich in carotene and lycopene. The normal outdoor growing season is summer and autumn, and the ancient name is June persimmon and good news three yuan. Native to Peru and Mexico in South America, it was originally called 'wolf peach'. The fruit is rich in nutrients and has a special flavor. It can be eaten raw, cooked, processed into ketchup, juice or canned whole fruit. Tomatoes are one of the most widely cultivated fruits and vegetables in the world, cultivated in greenhouses, plastic greenhouses and other conservation facilities. ”

"It first grew in South America, because of the delicate color, people are very wary of it, as the" fox fruit ", also known as the wolf peach, only for viewing, dare not taste, later a painter, when painting tomatoes, hunger and thirst, really can't help but eat one, since then tomatoes have entered the table, Westerners called tomatoes, after the introduction of China, because of the similar appearance with our persimmons, so we call it 'tomatoes', and now it is an indispensable delicacy in people's daily life."

——

"Wow, so much knowledge, you know, Binbin is amazing!"

No wonder Binbin reveled in explaining to the little girl, this voice of exclamation, worship and praise is so beautiful! Babe, how does he know English? Four-dimensional space is still in English? "Zhu Lang was shocked.

Bei Bei said nonchalantly: "All ethnic groups share an ancient language, but they also have their own unique language. This is not surprising, there are so many ethnic minorities in China, don't they all have their own national languages? There are also their own dialects within the Han people. ”

Zhu Lang is relieved.

At this time, the light curtain popped up above Beibei's head, and there was a shaking, and a line of words was displayed on it: [Question 1]. What sensory organs are used to identify whether tomatoes are ripe? Interpret the vision.

Zhu Lang was a little confused, and thought: "Huh? Beibei, this time answering questions is interspersed in the course of the event? Can they see it? ”

"Yes, keep an eye on the light curtain, ready to answer questions. Only you can see it, and you can discuss it with your teammates and answer it. ”

At this time, Binbin was still explaining to the two beautiful girls: "You can taste the taste of the tomato by looking at the color, size, and shape of the tomato with your eyes, and pinching the softness and hardness of the tomato." The answer is eyes, hands, tongue. Vision is a physiological word. Light acts on the visual organ, the eye, causing it to feel the excitement of the cells, and its information is processed by the visual nervous system to produce vision. Through vision, people and animals perceive the size, brightness and darkness, color, movement and stillness of external objects, and obtain various information that is of great significance to the survival of the body, at least more than 80% of the external information is obtained through vision, and vision is the most important feeling of people and animals. ”

Zhu Lang has a super good memory, and recites it word for word......" If you answer correctly, you will be rewarded with 30 team points; In addition, 100 team points will be awarded for erudition. ”

Zhu Lang is happy: "Haha, check the information in advance to prepare, it really works!" - Even if it's a teammate, the effect is the same! ”

"Made, plagiarizing other people's achievements, and still being so upright and complacent, it's really black! …… Hey? Lord Beibei, Lao Tzu also scolded? Scared Lao Tzu trembling...... Lao Tzu is such a pure little white flower, but he was also damaged by the 'black-bellied man'! …… However, it feels so cool to scold......"

The smart dog was first disdainful, then frightened, then complained, and finally happy and seemed to enjoy it......

The four of them left the tomato greenhouse and came to the edge of a forest outside, on the left was the osmanthus tree, dotted with pale yellow osmanthus flowers, and the rich aroma of osmanthus hit people; On the right is the orange grove, the orange trees are full of orange-yellow fruits, and the branches are bent one by one; In the middle is the trail, and there are pots of chrysanthemums on the side of the road, and the flower colors are red, yellow, white, orange, purple, pink, dark red, etc., and there are many varieties.

The light curtain flickered again: [Question 2]. What organs are used to sense floral and fruity aromas? What kind of smell can you feel? Interpret the sense of smell. Say a sentence of ancient poetry about chrysanthemums.

The questions that Zhu Lang can answer naturally don't need to waste time and discuss with everyone, anyway, only his own answers are effective, so he will answer them directly; If you are really unsure or don't know, you will communicate and discuss with them.

"Beibei, I'll answer a little first, and then listen to the 'wall foot' if you don't know - smell the smell with your nose, you can smell fragrant, smelly, sour, fishy, as well as spicy, rotten, burnt and other pungent odors, most of what we smell is a mixture of different smells. I remember Yeon-yeon said last time that some flowers, fruits, etc. are poisonous, and don't smell unknown items casually. Zhu Lang replied for a while, and then continued: "The sense of smell is a kind of perception that is felt by the senses. There are olfactory cells in the nose...... The specific principle is not clear, I'll listen to what 'Sour Wood Man' has to say! ”

At this time, the 'sour wood man' happened to be popularizing the sense of smell to beautiful girls.

"Humans have the same olfactory system as other animals, but it's not as sensitive. The sense of smell is involved by two major sensory systems, the olfactory nervous system and the nasal trigeminal nervous system. Olfactory receptors are located at the top of the nasal cavity and are called olfactory mucosa, which contain epithelial cells that support function and specialized olfactory cells. The olfactory cells here are stimulated by external odor molecules to generate nerve impulses, which are transmitted along the olfactory nerve to the cerebral cortex and cause the sense of smell. Smell and taste integrate and interact with each other. Smell is a sense of distance, that is, it is the sensation of feeling a chemical stimulus over long distances. In contrast, taste is a sense of proximity. ”

Zhu Lang pricked up his ears and listened to it clearly, and hurriedly retold it while it was hot.

"The answer is correct, very detailed, and 20 team points and 30 team points will be awarded respectively."

The points obtained are not much, or 'hearsay', Zhu Lang is very unhappy, and laughs at himself: "Nima ~ Lao Tzu's poetry level is a half-ass, can't get it...... Lao Tzu has to ask his partners for advice. ”
