Identify four organelles that should be present in the eukaryotic organism and describe the function of each organelle.

The four organelles that should be present in the eukaryotic organism are: 1) Nucleus which contains the DNA and directs all of the activities of the cell 2) The Mitochondria which turns food in to energy 3) Ribosomes which make protein and 4) The Golgi Apparatus which processes the proteins.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
