Control and Coordination in Living Organisms

Study Notes

Control and Coordination refers to how organisms manage their activities through internal mechanisms. This can be seen in both humans and other living beings like plants. Here we'll discuss control and coordination by looking at specific examples such as the human eye, plant movements, and key parts of our body responsible for these processes - namely the nervous system and endocrine system.

The Human Eye is a prime example of control and coordination because it has several structures that work together to gather information from its surroundings. For instance, the lens focuses light entering the pupil onto the retina where photoreceptor cells translate this into electrical signals which travel via nerves to your brain. This process allows you to see images clearly even when there isn't enough natural light available. It also means that if one part of your visual apparatus breaks down, another takes over automatically thanks to built-in backup systems within the human body.

Coordination in Plants works differently compared to animals because they lack the complex centralized nerve networks found in most animals. However, they do have specialized proteins called 'kinases', which help them sense environmental changes and regulate growth responses accordingly. In summary, while not having eyes per se, plants still exhibit some form of sensory perception and response mechanism based upon changes around them.

Human Eye Structure consists primarily of two layers; an outer sclera layer made up mostly of collagen fibers and a thin inner choroidal vascular layer containing blood vessels that supply oxygen to the back surface of the cornea. On top lies what's known as the conjunctiva membrane along with tear ducts that lubricate the entire area continuously. The vitreous humor fills out much of the interior space inside our eyeballs where lenses focus incoming light rays until they strike sensitive cellular tissue on back walls called rods & cones.

The Nervous System plays a critical role in controlling movement in response to stimuli originating either internally (e.g., hunger) or externally (foreign particles invading tissues). The basic design principle behind all neurons is similar across species - each cell contains an axon extending from it towards other nearby cells, forming connections known collectively as synapses. These synaptic bridges allow for communication between various regions of brain matter without requiring physical contact among individual cells themselves.

Lastly, the Endocrine System is involved in hormone production and secretion. Hormones are chemical messengers produced by glands such as thyroid, pituitary etc., allowing us to respond appropriately depending on external conditions. While less physically visible compared to neuronal components, endocrine organs nonetheless exert powerful influence over body function via feedback loops involving circulatory fluid pathways throughout our bodies.

In conclusion, humans possess sophisticated structures capable of processing vast amounts of data rapidly due largely to interplay among various elements including vision centers in eyes and regulators elsewhere within organism like those mentioned above. Humans aren't alone though—plants too share some degree of sensitivity/responsiveness albeit more passive forms relative to animal counterparts. And underlying all activity from eyelid blinking down to whole body reactions lies combination of nervous&endocrine systems working harmoniously
