 Lục lạp là nơi chứa chất diệp lục, bào quan này giữ nhiệm vụ hấp thụ ánh sáng mặt trời để thực hiện quá trình quang hợ

ởi vì thực vật có chứa phần lục lạp ; đây là bào quan chứa sắc tố có khả năng hấp thụ năng lượng ánh sáng để quang hợp

a: \(\left(-256\right)\cdot45-256\cdot56+256\)

\(=256\left(-45-56+1\right)\)

\(=256\left(-100\right)=-25600\)

b: \(\left(-2\right)^3\cdot1975\cdot\left(-4\right)\cdot\left(-5\right)^3\cdot25\)

\(=\left(-8\right)\cdot\left(-125\right)\cdot\left(-4\right)\cdot25\cdot1975\)

\(=1000\cdot\left(-100\right)\cdot1975=-197500000\)

c: \(2076-1976\cdot65-1976\cdot35\)

\(=2076-1976\left(65+35\right)\)

\(=2076-1976\cdot100=2076-197600=-195524\)

d: \(-437-25\cdot78+25\cdot178\)

\(=-437+25\left(178-78\right)\)

\(=-437+2500=2063\)
