Ответ:Источник энергии для синтеза АТФ в клетках автотрофов - это энергия квантов солнечного света. Хлорофилл, находящийся в пластидах их клеток, поглощает кванты света и обеспечивает преобразование энергии излучения в энергию электрохимического градиента биологических мембран (в первую очередь - мембран митохондрий). За счет этой энергии и происходит синтез АТФ.

Фотосинтез — процесс, при котором в клетках, содержащих хлорофилл, под действием энергии света образуются органические вещества из неорганических. При фотосинтезе растение поглощает углекислый газ и воду, синтезирует органические вещества и выделяет кислород, как побочный продукт фотосинтеза.

Процессы фотосинтеза идут в тканях, содержащих хлоропласты, — преимущественно, в листе, на который приходится большая часть процессов фотосинтеза. Такая ткань называется хлоренхима, или мезофилл.

Вот текст:
The Bottle
10 July was a very special day. In fact, it was Jack Peterson's birthday. On that day everybody tried to do something nice for him. Mum and Dad always gave him a lot of presents and took him to interesting places. Two years ago they went on an excursion to Mars. Last year they went to the Galaxy Zoo. They saw interesting animals there: bats, rabbits, hens and the most exciting thing: a real dog!
Yes, all Jack's birthdays were great, but this year — 2170 — his Grandfather promised him the best present. "On your birthday^' Granddad said, "we'll go camping!"
"Camping?" Jack didn't know this word, so he wasn't really interested, but suddenly he heard his mum's voice.
"Camping!" she cried. "What are you talking about?" "You can't put the life of my child in danger!" "It'll be OK, Kate," Grandfather sighed. "We'll wear our masks and we'll take a lot of extra oxygen with us." 'And you won't touch anything! Do you promise, Dad?" Jack's mum shouted. "Of course I promise," Granddad answered. After this conversation Jack really wanted to go camping. "Camping is dangerous - it's a real adventure," he thought.
On the morning of 10 July Granddad woke Jack up very early. They put their masks on and went outside. It was dark. Jack knew about the sun, but he never saw it. They went to the forest. There were six trees and a little river. Grandfather found a stick and started digging a hole in the ground. He looked sad. "What are we going to do?" Jack asked. "Well, you can touch the water in the river, but don't forget to clean your hands after that. Or we can play hide-and-seek'" Grandfather sighed. "Is that all camping is, Granddad?" Jack cried. "Then camping is the most boring thing in the world!"
"It used to be fun in my time," Granddad sighed again. 'And what was it like?" Jack asked. "In my time we used to go out without oxygen and masks. The air used to be good and clean, the sun used to shine and it used to be warm." "You are joking, Granddad!" Jack said.
"No, it is true. We used to stay in this forest for two or three weeks. Yes, yes. This forest used to be very big."
'And where did you use to sleep?" Jack asked. "We used to sleep in tents on the ground. This place near the river used to be our campsite."
'And what did you use to eat?" Jack asked. "We used to cook our food on the campfire. We also used to pick berries and mushrooms. They were tasty'' "Now I know you are pulling my leg, Granddad," Jack said. "Berries and mushrooms are poisonous. Every child knows that." "They didn't use to be poisonous in our time. And I'll tell you more. We used to swim in this river and drink the water from it." Grandfather stopped digging. There was something in the hole. Jack picked it up. It was a very old plastic bottle. There was some paper in it. Granddad took the paper out and read it. "Sam Peterson loves Susan Brown," the note read.
"Cool! Is that your bottle, Granddad? Who is Susan Brown?" Jack asked.
But Granddad didn't say anything. His face was as red as a beetroot. He took Jack's arm and said, "You want to see the spaceship race today, don't you? Then we must go home. I think camping was a really bad idea."
