Answer:
1) Better access to food
2) Safety
3) Protection of vital organs
4) Recreation
5) Improved separation of tasks among organs (division of labor labor)
6) Increased potential energy
Step-by-step explanation:
1) Better access to food
The upright growth of plants enable them to access the Sun's energy during photosynthesis for the production of glucose and oxygen without the need to move far for food
2) Safety
Growing upright help protect the food produced by the plant such as fruits from crawling animals and also protects the loosely attached leaves and fruits from the impact of kinetic energy of flood waters
3) Protection of vital organs
Having vital organs stored away from areas that cause due to the energy of falling objects or the motion fluid along side particles that the fluid (wind or water) may carry such as debris is important for the survival of an organism. Vital organs are also protected from being trampled upon
4) Recreation
Growing uptight enables the seeds of the fruits of a tree to be dispersed to more distant locations such that the new offspring may find an improved growing environment
5) Improved separation of tasks among organs (division of labor labor)
Growing upright encourages compartmentalization, such that different parts of the plant perform specific functions to prolong the plant life
6) Increased potential energy
The energy output of an organism growing upright is more than one that is growing sideways which results in better survival probability.
