1. Therefore, the structures of animal and plant cells are cell membrane, cytoplasm, nucleus and mitochondria. The unique structures of plant cells are cell walls, chloroplasts and vesicles. ( 3) In the pictureBacteria and fungi are decomposers in ecosystems, which play an important role in the circulation of matter in nature.
1. Draw grass, rabbits and tigers first. Connect according to the food chain, and the arrow points to the predator. Information expansion: Food chain is an ecological term first proposed by British animal ecologist Elton in 1927.
2. Green plants → rats → wolves (2) Predation (3) Food net (4) 1:1; The automatic adjustment ability of the ecosystem is limited.
3. There are 5 food chains. The relationship between foxes and rabbits is formed between predators and prey. The longest food chain is: grass-mouse-snake-eagle.
Text annotation: It can represent the relationship between concepts on different nodes, a detailed explanation of the concepts on the node, and a relevant description of the whole diagram. Features (1) Hierarchical structure uses hierarchical structure to express the relationship between concepts. In the concept map, the concept is presented in the way of hierarchical structure.
Concept map is a tool used to organize and characterize knowledge.Concept map is a diagram that uses nodes to represent concepts and connect to represent the relationship between concepts. The theoretical basis of the concept map is the learning theory of Ausubel. The construction of knowledge begins through the observation and understanding of things through existing concepts.
Concept map is a diagram method that uses nodes to represent concepts and connect to represent the interrelationship between concepts. It is a visual teaching tool and thinking tool proposed by Professor Novak of Cornell University and others in the 1960s based on Osubel's learning theory. The concept map has three basic features. First, the characteristics of hierarchical structure.
Concepts, propositions, cross-connections and hierarchical structures are the four basic chart features of conceptual diagrams. Its advantage is that it can clearly present the logical relationship between concepts and propositions, which is convenient for students to integrate new knowledge into the existing knowledge structure.It is suitable for the study of complex knowledge such as concepts and principles.
Concept map means that in order to create meaningful learning, learners themselves should connect new knowledge with the concept of old knowledge, and gradually expand the detailed content and details according to the established conceptual relationship diagram.
In the brain and spinal cord, the place where the cell body is dense, the color is dark gray, called gray matter, the protrusion of neurons is mainly concentrated in the peripheral nervous system, and the gathering of nerve fibers in the brain and spinal cord Position, the color is bright white, called white matter, and the structure [E] in the figure is composed of neuronal cell bodies.
And neurons are crisscrossed and interconnected, forming a information transmission network that runs through the whole body - neural tissue. Comment: This question is a basic question, which is not difficult. The key to solving this question is to memorize the structure and function of the nervous system. The basic unit is neurons, which can be memorized in combination with the structural diagram.
