A membrana plasmática é basicamente uma borda entre o interior de uma célula e seu exterior. A membrana regula o que entra e sai da célula e é necessária para a sobrevivência da célula. sem ele, todo o conteúdo da célula se espalharia. Isso seria ruim. Cada célula tem uma membrana, assim como as organelas dentro da célula.

The answer is coevolution.

Coevolution is a change in <span>one species that results from a change in another species that it interacts with. For example, some species of orchid and African moth coevolved.

This two species coevolved, therefore the orchids have deep flowers while African moths have long proboscides.</span>

Three organelles (cell parts) found in plant cells, but not animal cells?
allsm [11]
1. The Cell Wall.

Plants have a cell wall in order to maintain rigidity and stability. Animal cells do not have a cell wall because they have a different structure, which makes them more flexible and able to move around easier.

2. Chloroplasts

Since plants cannot move, they get their energy from the sun. This energy is made inside of the chloroplasts. Animal cells don't have chloroplasts because their energy comes from other organisms.

3. Central Vacuole

The central vacuole provides structure and holds materials and wastes, and also decomposes those wastes. Animal cells don't have a central vacuole because they have lysosomes and normal vacuoles that do the same function.
