Double fertilization occurs in Angiosperms
Answer is hypertonic.
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.
Cell wall
Chloroplasts
Everything else, I believe, are in both animal and plant cells.
I hope this helps!
The bacteria was not killed off. In those three days symptoms had stop because the bacteria was dormant. They must have been activated because Jim provided a suitable environment for their growth
