When a cell gains water, what happens to its size and weight

 Water will move across the semi-permeable membrane in order to balance both sides until they are neutral.

"Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permeable membrane is one that allows unrestricted passage of water, but not solute molecules or ions."

Or

When a cell gains water it becomes much bigger and heavier which could possibly lead to its explosion.

"Water moving into a cell can make the cell swell, or even burst! This happens when cells are placed into a hypotonic solution. Like the egg in distilled (pure) water. Water leaving a cell can make it shrivel up"

When a cell gains water, the size will expand, making the cell bigger, and the weight will increase, depending on the type of cell as well as the amount of water.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
