为探究番茄果实的结构层次，某兴趣小组将番茄的果皮.果肉及“筋络”分别制成临时装片，看到如下三个显微物像。请据图分析：（8分）

⑴制作番茄临时装片时，应用到的实验用具主要有解剖针、镊子、滴管、洁净的载玻片和

          等。

⑵用显微镜观察临时装片时，应转动           ，使低倍物镜对准通光孔，并将玻片标本放在载物台上正对通光孔的中心。

⑶显微镜下，番茄果肉的细胞壁薄、液泡大、细胞饱满，属于       组织，如图[   ]。

⑷观察到的“筋络” 能运送营养物质和水分，主要属于      组织，其运送的水分由植物的      （器官）从土壤中吸收，吸收和运送水分的动力来自植物的       作用。这种组织贯穿于植物体的各个器官中，将植物体联系成统一的整体。

⑸番茄果实由多种组织按一定顺序结合起来，说明番茄果实所属的结构层次是      。

      "Grandma, Grandma, tell us a story!" Four darling children sat by my feet, looking up at me

expectantly.

     Suddenly, we were interrupted clapping. "Terrific," the director said, stepping up the stage from

the aisle(过道). "Except, could you kids face the audience a bit more?"

     The kids shifted to face the empty seats, which would be filled in a few days for the church play.

"Perfect," the director said. "Now, Grandma, read to your grandchildren." A pang of sadness hit me.

If only I could read to my real grandchild!

     I had a granddaughter, but I'd never met her. Sixteen years earlier my son was involved in a

relationship that ended badly. But out of it came a blessing: a baby girl named Lena. I hoped to be a

grandmother to her-but shortly after the birth, the mother moved without any address left. Over the

years, I asked around town to try and find my son's exwife(前妻), but it seemed that she didn't want

to be found.

     I 'd just joined this new church a week earlier, and was at once offered the part of Grandma in the

play.  At least now I could pretend to be a grandma. The rehearsals went well, and finally the day of

the show arrived. The performance was great. "You all looked so natural up there," one of my friends

said.

     Afterward, we went to the church basement for refreshments(茶点). I walked over to one of the

girls in the play, Rehearsals had been such a whirlwind(一片忙乱) that we never really got to talk.

"How's my granddaughter?" I joked.

     "Fine!" she answered. Just then, someone else walked up and asked the girl her name.

     I wasn't sure I heard the girl's answer correctly. But it made me ask her another question. "What's

your mother's name?"

    She told me, I was still in shock. "And what's your father's name?" I asked. She told me. It was my

son.

    She'd only started going to that church a week before I did. Since that day of the play, we've stayed

close. Not long ago, she even made me a great grandma.
