Question

how do the materials lysosomes break down get removed from the cell? which organelles are involved? a they stay inside the lysosomes forever. b they are recycled by the vacuole and removed by the cell membrane c they are used by the chloroplast and stored in the cell wall. d they are sent to the nucleus to be turned into dna. why would a cell \waste\ energy on active transport? a to save energy and move things from high to low concentration. b to let oxygen float freely through the membrane. c to move materials from low to high concentration when diffusion cant do it. d to slow down cell processes.

Explanation:

For the first question, lysosomes break - down materials, some are recycled by the cell. The vacuole can recycle and the cell membrane can remove waste. For the second question, active transport uses energy to move substances against the concentration gradient (from low to high concentration) when diffusion is insufficient.

Answer:

1. B. They are recycled by the vacuole and removed by the cell membrane
2. C. To move materials from low to high concentration when diffusion can't do it.
