There are three major structures that are found in plant cells that aren't found in animal cells. These are chloroplasts, (which is where the process photosynthesis takes place), a cell wall (which keeps the structure of the cell), and a large central vacuole, (which stores extra food/water). Don't make the mistake, though. Animal cells have vacuoles, but they are just smaller and not as important, because they have a different way of excreting waste, which plant cells cannot do.
Answer:
B) they are the starting materials for cellular respiration
It gives the plant air and food
The factor that does not help determine whether a volcanic eruption will be explosive or relatively quiet is the composition of the lava.
On the other hand, the composition of the magma, the temperature of the magma, and the amount of dissolved gases in the magma are quite important for determining this.
