А.Образуются в комплексе Гольджи . Содержат набор гидролитических ферментов. С их помощью осуществляется внутриклеточное пищеварение. У растений функции лизосом сравнимы с некоторыми функциями вакуолей .
В.
Ферменты лизосом могут оказывать благотворное воздействие на клетку и организм в целом. Лизосомы переваривают не только необходимые вещества, но и уничтожают вредные, ненужные клетке элементы (участвуют в обновлении клеток) . Ферменты лизосомы расщепляют и произведенные самой клеткой белковые соединения. Этот процесс назван биологами аутофагией.
Б.
Лизосомы - одномембранные органоиды

Б.
В комлексе Гольджи вщества, необходимые самой клетке, например пищеварительные ферменты, "упаковываются" в мембранные пузырьки, отпочковываются и разносятся по цитоплазме. В коплексе Гольджи также накапливаются вещества, которые клетка синтезирует для нужд всего организма и которые выводятся из клетки наружу.
В.
Различают два вида ЭПС: 1) шероховатая (гранулярная), содержащая на своей поверхности рибосомы, и 2) гладкая (агранулярная), мембраны которой рибосом не несут.
Г.
Функции: 1) транспорт веществ из одной части клетки в другую, 2) разделение цитоплазмы клетки на компартменты ( «отсеки»), 3) синтез углеводов и липидов (гладкая ЭПС), 4) синтез белка (шероховатая ЭПС), 5) место образования аппарата Гольджи.
