Biology Quiz

Prepared by:

biology teacher

Konstantinovskaya secondary school I-III st.

Melnichenko Svetlana Leonidovna

Simferopol 2014

This quiz was developed by me to review and consolidate students' knowledge. Here are questions from the 7th and 8th grade courses (botanists and zoologists). Two teams are invited to participate, in which there are students from the classes listed above. A projector is used for the presentation, and all slides are clearly visible to the participating teams. Hints, puzzles, encrypted words and other things are laid out on the tables. visual material. Questions are asked to teams in turn, and before answering orally, participants must find their answer on encrypted cards. For example: questions about flowers are not very difficult, but there are more illustrations, and many similar ones, which sometimes confuses children and makes them doubt the correctness of their answer, which encourages deeper reasoning. The names of the birds are encrypted in puzzles. But, before answering the question about berries, you need to indicate the color of this berry on the card. Name the right fish you need to choose, and a large quantity. The vegetable card contains an illustration of about 20 incorrect answers.

Medicinal herbs are depicted mixed with wild ones. The names of the trees are located on the cards back to front. And rhymes were chosen for the names of the mushrooms (copper gypsy - pale toadstool).

The purpose of this extracurricular activity, is to stimulate further interest in the study of biology. The questions were chosen, simple, but interesting, forcing the children to think, and those who read additional literature or watch a program about nature can easily cope with them. IN modern world It can be difficult to attract the attention of schoolchildren to living nature, due to the mass computer technology, they cease to be interested in biology. By holding such events, you can return students' interest in botany and zoology. After all, zoology has always been one of the most beloved branches of biology.

Guys, today we will give you a biological quiz. Who knows what "biology" is?

“Biology” is the science of living nature (plants, animals, humans). Biology consists of several sciences. Animal world studies “zoology”, the world of plants - “botany”, the structure of the human body - “anatomy”. At our event we will touch on zoology and botany, ornithology and mycology, and other branches of biology.

So, let's split into two teams. Come up with a name and motto for your team.

And now we take a journey through the pages of biology. We will visit such sections as botany, zoology, mycology, ornithology, floristry, ichthyology, dendrology and much more. The judges will decide whoever prepared the name and motto better will be the first to participate in the quiz.

In this section you will find materials for conducting a trial Olympiad in biology, during which 7th grade students will be able to generalize and consolidate their knowledge, learn to apply it to solve entertaining non-standard problems. Biology teachers should use the sample assignments provided to help students prepare for the Olympiad.

However, the tasks collected on this page can be used not only in lessons, but also as homework. Students will be able to evaluate and test themselves, because the correct answers are indicated for all questions and tasks. We have prepared both test answers and complex ones.

Answers to open questions

Answer to question 1:
Based on the degree of damage caused to trees, these fisheries can be divided into 3 groups:
1. Minimal harm. To prepare willow twigs, last year's branches are cut off (the older ones are too thick), which are easily renewed. In addition, willow reproduces rapidly both vegetatively and by seeds. So it is quite difficult to sharply reduce the number of willow trees in nature.
2. “Moderate severity” damage. When collecting birch sap and resin, significant harm is caused to trees, since spores easily penetrate through cuts in the bark pathogenic fungi. In order to reduce damage, it is necessary to properly organize the collection of birch sap and resin.
3. Greatest harm. When removing bark from birch and linden, the current is completely interrupted organic matter, and the tree may die. As a result of such actions, undergrowth is destroyed, as a result of which forest regeneration is disrupted.

Answer to question 2:
Among cartilaginous fish, only a few, for example, the polar shark, spawn. Most of them are characterized by either the birth of live young or the laying of large, already fertilized eggs rich in yolk. Among bony fish, viviparity, on the contrary, occurs as an exception. These are Baikal golomyanka, swordtail, sea bass.

Answer to question 3:
If a live frog is placed in a jar with a small amount water, then transparent films will soon appear in it - these are shreds of the upper layer of skin that has faded from the frog. Examining such a patch under a microscope, you can see that it consists of many rectangular cells, closely adjacent to each other. All the cells lining the surface of the frog's body form its outer integumentary tissue.

Answer to question 4:
As is known, Linnaeus called the highest group of the animal kingdom “primates,” into which he included anthropoid monkeys and man himself. Closer acquaintance with higher mollusks, with their diversity and perfection adaptive features, the complexity of their behavior, sometimes reminiscent of the action of a rational being, which is due to the high development nervous system, gives reason to see in this group of invertebrates “primates of the marine kingdom” - creatures, in terms of their level of development, not inferior to monkeys among terrestrial vertebrates. Of all the cephalopods, octopuses, animals that have not followed the path of one-sided adaptation to fast movement, display the greatest “intelligence” in their behavior.

Answer to question 5:
The property of hemoglobin to bind oxygen is vital for the body. Sometimes people die from lack of oxygen in the body, surrounded by the most clean air. This can happen to a person who finds himself in conditions low blood pressure(at high altitudes), where the thin atmosphere has a very low partial pressure of oxygen. Partial pressure of oxygen is the part of the total pressure that accounts for the share of oxygen in the atmosphere. The cause of death was a sharp decrease in the partial pressure of oxygen at high altitude. At high altitudes (7-8 km), arterial blood in its gas composition approaches venous blood; all tissues of the body begin to experience an acute lack of oxygen, which leads to serious consequences. Climbing to altitudes above 5000 m usually requires the use of special oxygen devices.

With special training, the human body can adapt to the reduced oxygen content in atmospheric air. A trained person’s breathing deepens, the number of red blood cells in the blood increases due to their increased formation in the hematopoietic organs and their supply from the blood depot. In addition, heart contractions increase, which leads to an increase in minute blood volume.
