Sometimes when plants are under water stress, they wilt. Animals do not wilt! Review the plant cell structure. What analogy based on the plant cell structure explains wilting?
A) The chloroplast are like a factory. When the plant is water stressed, the chloroplast stops producing energy and the plant wilts.
B) The cell wall is like a cardboard box. When the plant is water stressed, the cell wall folds, like someone crushing the cardboard box.
C) The large vacuole is like a water-filled balloon. When the plant is water stressed, the water leaves the vacuole and the cells shrinks.
D) The plasma membrane is like the drain in your sink. When the plant is water stressed, the plasma membrane stops water from going into and out of the cell.

multiply it by 5 in order for you to understand i cant give an exact answer.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
