(2)(6分)

分析:1)B/A值越小,說明質壁分離程度越大;

2)隨著溶液濃度的增加,B/A值下降,說明質壁分離程度隨溶液濃度的增加而增大。

結論:細胞失水量隨著外界溶液濃度的增大而增加

(得分點:分析到數(shù)值,結論到結構發(fā)生的變化)

(3) (6分)設置清水對照組,觀察清水中的黑藻細胞,確認其細胞形態(tài)正常,無質壁分離現(xiàn)象。

(4)(6分)

方案一:

1)取鹽堿植物與黑藻植物葉片若干,用吸水紙吸干水分;

2)配制相同濃度的蔗糖溶液,將上兩種葉片浸入10分鐘;

3)兩種葉片制成裝片,觀察;比較B/A值的大小。

4)B/A值小,質壁分離程度大,說明細胞液濃度低。

   方案二:

1)選用鹽堿植物葉片,如上實驗,增加低于10%的濃度并細化濃度;

2)黑藻細胞增加低于10%的濃度,細化;

3)剛開始發(fā)生質壁分離的濃度與細胞液濃度相當

4)比較黑藻與鹽堿植物的細胞液濃度

物理答案

17.答案(1)①粒子在O'Q間射出,軌跡如圖所示。

  由 qv0B=mv02/R               (2分)

  得R1=mv0/qB1                        (1分)

  同理得  R2=mv0/qB2                 (1分)

d=R1+R2(3分)

  因此d              (2分)

②粒子在磁場B1中做圓周運動的周期,在磁場B2中做圓周運動的周期  (2分)

粒子在O'Q間射出,在兩個磁場中分別經(jīng)歷2n十1個,

所以  (3分)
