rift valley. 1  A long, narrow valley lying between two normal geologic faults. Rift valleys usually form where the Earth's lithosphere has become thin through extension associated with plate-tectonic processes. 2  The deep undersea valley located along the center of the mid-ocean ridge.
Vacuoles and lysosomes have similar functions. Vacuoles in plant cells are in some respects the equivalent of lysosomes in animal cells. The environment inside a vacuole is slightly acid (pH about 5.0) whilst for the rest of the cytosol it is slightly alkaline (about pH 7.2).acuoles and lysosomes have similar functions.

What does a vacuole store in a plant cell? Vacuoles are found in the cytoplasm of most plant cells and some animal cells. Vacuoles are membrane-bound compartments within some eukaryote cells that can serve a variety o â¦ f secretory, excretory, and storage functions.
