In plant cell what does the vacuole do

Answers

I found this on a website..... Hope this helped :)

"In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food."

Some insecticides interfere with the removal of acetylcholine from the synaptic cleft. what effect will this have on muscle contraction

Answers

The effect of insecticides will result in prolonged muscle contraction.   Acetylcholinesterases are the enzymes that catalyze the breakdown of acetylcholine (Ach) in the synaptic cleft. This normally occurs, after the Ach achieves its effects on its receptors. On the other hand, acetylcholinesterase inhibitors inhibits the acetylcholinesterase enzyme thereby increasing the level and duration of action of the neurotransmitter ACh. Acetylcholinesterase inhibitors are used as insecticides.
