What is a plant stoma?
plant stomasare tiny, microscopic pores located on xem bóng đá trực tiếp vtv2 surface of leaves, young stems, and some other plant parts. They function like small "windows," allowing plants to exchange gases with xem bóng đá trực tiếp vtv2 external environment.
Students can refer to xem bóng đá trực tiếp vtv2 information about plant stoma:

In Vietnam, what is xem bóng đá trực tiếp vtv2 grade at whichthe plant stoma is taught?
Under section 5 of xem bóng đá trực tiếp vtv2 General education program in Natural Sciences issued withCircular 32/2018/TT-BGDDT, xem bóng đá trực tiếp vtv2 content of 7th-grade natural scienceincludes:
Material and Energy Exchanges in Organisms
...
- Describe xem bóng đá trực tiếp vtv2 process of energy transformation in cells, including:
+ Provide a general description of xem bóng đá trực tiếp vtv2 photosynthesis process in leaf cells: State xem bóng đá trực tiếp vtv2 role of leaves in photosynthesis. Define xem bóng đá trực tiếp vtv2 concept, raw materials, and products of photosynthesis. Write a word equation for photosynthesis. Draw a diagram depicting photosynthesis in leaves, thus indicating xem bóng đá trực tiếp vtv2 relationship between material exchange and energy transformation.
+ Apply understanding of photosynthesis to explain xem bóng đá trực tiếp vtv2 practical significance of planting and protecting green trees.
+ Provide a general description of xem bóng đá trực tiếp vtv2 respiration process in cells (in plants and animals): Define xem bóng đá trực tiếp vtv2 concept; write a word equation for respiration showing synthesis and breakdown.
+ List some key factors affecting cellular photosynthesis and respiration.
+ Apply understanding of cellular respiration in practice (e.g., drying seeds for preservation,...).
+ Conduct experiments to demonstrate photosynthesis in green plants.
+ Conduct experiments on cellular respiration in plants through seed germination.
- Material and energy exchange
+ Gas exchange - Use images to describe xem bóng đá trực tiếp vtv2 gas exchange process through leaf stomata.
- Describe xem bóng đá trực tiếp vtv2 structure of stomata using drawings, stating their function.
- Using diagrams, describe xem bóng đá trực tiếp vtv2 pathway of gas through xem bóng đá trực tiếp vtv2 respiratory organs in animals (e.g., humans).
+ Water and nutrient exchange in organisms - State xem bóng đá trực tiếp vtv2 role of water and nutrients for living organisms.
- Using diagrams (or models), describe xem bóng đá trực tiếp vtv2 chemical composition, structure, and properties of water.
- Describe xem bóng đá trực tiếp vtv2 process of water and nutrient exchange, using examples from plants and animals, specifically:
+ Using simple diagrams to depict xem bóng đá trực tiếp vtv2 pathway of water and mineral absorption, transport in plants from xem bóng đá trực tiếp vtv2 external environment to xem bóng đá trực tiếp vtv2 root hair zone, into roots, up through stems, and into leaves;
+ Using diagrams, images, distinguish xem bóng đá trực tiếp vtv2 transport of substances in xem bóng đá trực tiếp vtv2 xylem from roots to leaves (upward flow) and from leaves to various organs through xem bóng đá trực tiếp vtv2 phloem (downward flow);
+ State xem bóng đá trực tiếp vtv2 role of transpiration in leaves and xem bóng đá trực tiếp vtv2 action of opening and closing stomata during transpiration;
+ List key factors affecting water and nutrient exchanges in plants;
+ Conduct experiments proving stems transport water and leaves transpire;
...
Thus, according to xem bóng đá trực tiếp vtv2 above regulations, 7th-grade students will learn about plant stomata.
