- A. tips
- B. hyphae
- C. enzymes
- D. walls
Lời giải tham khảo:
Đáp án đúng: D
Đáp án D
Thông tin trong bài: "The difference between the chemical composition of the cell walls of fungi and those of plants is of enormous importance because it enables the tips of the growing hyphae, the threadlike cells of the fungus, to secrete enzymes that break down the walls of plant cells without having any effect on those of the fungus itself."
Dịch: Sự khác biệt giữa thành phần hóa học của thành tế bào của nấm và của thực vật có tầm quan trọng to lớn vì nó cho phép các đầu sợi nấm đang phát triển, các tế bào dạng sợi của nấm, tiết ra các enzym phá vô thành tế bào thực vật mà không ảnh hưởng gì đến thành tế bào của nấm.
⇒ those = the walls
