‘Make hay while the sun shines’ so goes the old saw. For a plant it is just vital to photosynthesize while the sun is up.

A plant in terms of nature holds similarities with man in that it has adapted for its stationary position. Consequentially roots, leaves instead of fingers are required to multi-task.
Water is drawn from soil and sent along the trunk, by means of capillary action. A stream goes the crown and also goes down like human circulatory system. In this we need to consider the mysterious cases of trees bleeding, redness which has nothing to do with actual blood our vessels carry.
Thrift is a human character which in case of plants is sending the sap to its roots before winter sleep. Of course a plant has no bank account but before winter a plant will send unwanted sap to its roots. How easy it is to distinguish a man according to his wealth in the bling bling he can afford. Of course no man has excelled in the sheer exuberance and fulness of red gold livery each tree can put out to show it has taken care of its surplus.
As David Attenborough in his popular BBC program The Life of Plants says, “”To find water a plant has to position its roots with just as much precision as it arranges its leaves… If moisture is in very short supply, it may have to drive a tap root deep into the ground to reach the water table.” Some desert plants may develop root systems that are far deeper than they are tall and extend laterally. Even if the environment is well-watered, a plant may still need to compete…, so it positions a network of roots closer to soil surface so when rain falls they could have the first fill.”In its farsightedness not to miss the action when it comes reveal nature has compensated life forms adequately and survival depends not so much as the outcome of a decisive battle where casualties exceeds millions and many more wounded or maimed in actions. Whether such strategy of nano corrections steadily applied to maximize the gains from changes in environment is more effective than of man whose policies run a gamut of feigned friendliness, treaties and cultural exchanges between peoples with intent to destabilize one another and saber rattling and conflict? Man’s outlay in achieving efficiency is with an eye to his complex social life where profits at the cost of decimating one another must percolate from nation building to line the pockets of those who thrive in conflicts.
Plants are no different in their needs, but being immobile their defenses tend to take a different form than they do in animals.
Plant defenses are grouped into three broad categories: chemical, physical, and co-optive.
In chemical defense plants may produce toxins and with pungent aromas, for example, poison ivy.What is repellant to other animals and meant as chemical defenses we consume with great relish, many of our foods and spices.Physical defenses are the most obvious to us, especially when they come in the form of thorns and barbs. Plants may defend itself by co-opting animals for defense. Ants are probably the animal most often co-opted by plants. Like humans, plants can manipulate-,via bribes, misrepresentation orchids tricking bees into trying to mate with the flowers is an example.

Lightly we foot it where our peers left off

As seasons crowd out the smooth with the rough;

We descend through tunnel of time, for sleep

And how others make do with theirs: enough.
