Cơ quan sinh dưỡng và cơ quan sinh sản của thực vật hạt kín giúp chúng có mặt ở nhiều nơi và thích nghi với nhiều điều kiện môi trường khác nhau nhờ vào các đặc điểm sau:

  1. Cơ quan sinh dưỡng (cây xanh):
    • Lá: Có khả năng quang hợp tốt, cung cấp năng lượng cho cây phát triển. Hình dạng và cấu trúc lá có thể thay đổi để thích nghi với các điều kiện môi trường khác nhau (ví dụ: lá nhỏ ở cây sống ở môi trường khô cằn, lá rộng ở cây sống trong rừng mưa nhiệt đới).
    • Rễ: Có khả năng hút nước và chất dinh dưỡng từ đất, có thể phát triển mạnh mẽ để tìm kiếm nguồn nước và dưỡng chất. Rễ của một số loài có khả năng dự trữ nước hoặc chất dinh dưỡng trong thời kỳ khô hạn.
  2. Cơ quan sinh sản (quả, hạt):
    • Quả: Quả của thực vật hạt kín có thể bảo vệ hạt khỏi các yếu tố bên ngoài và giúp hạt phát tán rộng rãi khi quả chín. Một số loài thực vật có quả được tạo ra để nhờ gió, động vật hay nước phát tán hạt.
    • Hạt: Hạt của thực vật hạt kín có cấu tạo vỏ cứng, giúp bảo vệ phôi hạt trong điều kiện khắc nghiệt. Hạt cũng có khả năng tồn tại trong thời gian dài mà không cần nước hay ánh sáng, điều này giúp hạt có thể nảy mầm khi điều kiện môi trường thuận lợi.

Một số loài thực vật hạt kín mà em biết:

  • Cây hoa hồng
  • Cây lúa
  • Cây đậu
  • Cây bàng
  • Cây thông
  • Cây dừa
  • Cây bắp

Các đặc điểm này giúp thực vật hạt kín phát tán rộng rãi và có thể sống ở nhiều nơi với những điều kiện môi trường khác nhau.

1 + 3 + 5 + ...+ (2x + 1) = 121

Xét dãy số: 1; 3; 5;... (2x + 1)

Đây là dãy số cách đều với khoảng cách là: 3 - 1 = 2

Số số hạng của dãy số trên là: (2x +1 - 1) : 2+ 1 = x + 1

Tổng của dãy số trên là:

(2x + 1 + 1).x : 2 = 121

[2x + (1+ 1)].(x + 1): 2 = 121

[2x + 2].(x + 1) : 2 = 121

(x + 1).(2 : 2).(x + 1) = 121

(x + 1).(x + 1) = 121

(x + 1)\(^2\) = 11\(^2\)

\(\left[\begin{array}{l}x+1=-11\\ x+1=11\end{array}\right.\)

\(\left[\begin{array}{l}x=-11-1\\ x=11-1\end{array}\right.\)

\(\left[\begin{array}{l}x=-12\\ x=10\end{array}\right.\)

Vì x là số tự nhiên nên x = 10

Vậy x = 10


Theo đề bài, ta có:

\(\left\lbrack\left(2x+1\right)+1\right\rbrack\cdot\left\lbrack\frac{\left(2x+1\right)-1}{2}+1\right\rbrack:2=121\)

\(\left\lbrack2x+2\right\rbrack\cdot\left\lbrack\frac{2x}{2}+1\right\rbrack=121\cdot2\)

\(\left\lbrack2x+2\right\rbrack\cdot\left\lbrack x+1\right\rbrack=242\)

\(2\left(x+1\right)\cdot\left(x+1\right)=242\)

\(\left(x+1\right)^2=242:2\) \(\left(x+1\right)^2=121\)

\(\left(x+1\right)^2=11^2=\left(-11\right)^2\)

\(TH1:\left(x+1\right)^2=11^2\)

\(x+1=11\)

\(x=11-1\)

\(x=10\)

\(TH2:\left(x+1\right)^2=\left(-11\right)^2\)

\(x+1=-11\)

\(x=-11-1\)

\(x=-12\)

Vậy x ∈ {10; -12}

\(\frac{5}{x+1}\) + \(\frac{4}{x+1}\) = \(\frac{3}{-13}\)

\(\frac{9}{x+1}\) = \(\frac{3}{-13}\)

\(x+1\) = 9 : (- \(\frac{3}{13}\))

\(x+1\) = - 39

\(x=-39-1\)

\(x=-40\)

Vậy \(x=-40\)

\(\frac{5}{x+1}+\frac{4}{x+1}=\frac{3}{-13}\)

\(\frac{5+4}{x+1}=\frac{3}{-13}\)

\(\frac{9}{x+1}=\frac{9}{-39}\)

x + 1 = -39

x = -39 - 1

x = -40

Vậy x = -40
