Which statement about vacuoles is true only plant cells contain vacuoles only animal cells contain vacuoles vacuoles are larger in plant cells than in animal cells vacuoles are larger in animal cells then in plant cells

Vacuoles are larger in plant cells than animal cells.

Explanation:

Vacuoles are cellular organnelles (membrane-bound organs) found in the cytoplasm of both plant and animals cells. They are enclosed structures filled mostly with water and salt. They are responsible for exporting waste products in the cell, storage of molecules including nutrients, enzymes etc. They also help store waste products, hence, keeping the cell less toxic.

Although both plant and animal cells contain vacuole but it is larger in the plant cell. It can be seen as a large central organnelle in the middle of a plant cell which occupies most of the cell's volume unlike animal cells which contains numerous but smaller vacuoles.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
