Which below are specialized for life in a hypotonic environment?
OLga [1]

Plant cells are specialized for life in a hypotonic environment.

Answer: Option A

<u>Explanation:</u>

A cell which lacks the cell wall, will expand and burst. At the point when set in a hypertonic solution, a cell without a cell wall will lose water to the surrounding, wilt and presumably die.

In a hypertonic arrangement, a cell with a cell divider will lose water as well. The plasma layer pulls from the cell wall as it withers, a procedure called plasmolysis. Thus it can be inferred that plant cell are specialized for life in a hypotonic environment.

The everglades were known as the wetlands due to the massive flooding that occurred often but these canals made it so that water would not flow into some of the areas in the Wetlands. Therefore, since water never reached these areas they quickly began drying up and making the ground infertile due to the lack of water which the plants need to survive.
