A cell in 1.5% NaCl is in a hypertonic solution .
For a cell to survive in its immediate environment, the movement of fluid is constantly being regulated.
The plasma membrane is selectively permeable and allows water and certain solute molecules to pass through it.
When a surrounding fluid and the cell contents have the same concentration, they are said to be isotonic. Example of such fluid is physiological saline that contains 0.9% NaCl.
When the fluid surrounding the cell is more concentrated (1.5% of NaCl) than the inside of the cell, it is said to be hypertonic.
Therefore the cell in 1.5% NaCl is in a hypertonic solution .

Closely related organisms pass through similar embryonic stages. The earlier the divergence of embryos occurs between two species, the more distant their most recent common ancestor, as with the vertebrate/insect gastrea example above
Two types of population growth patterns may occur depending on specific environmental conditions: An exponential growth pattern (J curve) occurs in an ideal, unlimited environment. A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth.
Hello! The answer to your question would be as followed:

Answer:
The plant used everything around it in order to continue growing.
Explanation:
Although nothing was added, the plant might have had a rich soil, so with that rich soil it was able to grow on its own. The plant might have been placed near a window, so it had enough sunlight in the day. And, the classroom might have had a air-conditioned room flowing, with enough space for the plant to grow in.
Hope this helps :D
