DNA Learn It: Describe the commonfeatures of all lifeforms.What does it mean to be alive? What key features or characteristicsare common to all living things?Let's start with one of the most basic and obvious key features of allliving things. How does any living thing get here in the first place? Allorganisms are offspring of their predecessors and are generated bythe process of reproduction. Although reproduction can varydramatically from one organism to the next, when an organismproduces offspring, the offspring receives hereditary information inthe form of DNA. All organisms receive their DNA from theirpredecessors or parents, whether an organism is as simple as abacterium receiving DNA from one parent or something much morecomplex like you, receiving DNA from two parents. This process oftransmitting DNA from parent to offspring is called inheritance, and itis not only intimately related to the process of reproduction, but alsoessential to the continuance of all life forms..As you know, even complex organisms begin as a single cell. Forinstance, you began as a single fertilized egg. As you developed froma single cell into a much larger multicellular organism. vou increasedLearn It: Describe the commonfeatures of all lifeforms.a single cell into a much larger multicellular organism, you increasedin size, volume, and number of cells. Growth was a naturalprerequisite. Can you imagine the amount of energy required to fuelthat kind of growth? All organisms require energy to fuel theseprocesses, and that energy comes in the form of nutrients. All livingthings require nutrients, but how they acquire nutrients may vary.Consider the many types of plants growing in the world around you.All of them can harness the energy of sunlight to produce sugar fromatmospheric CO2 and water in a process called photosynthesis. This iswhy they are categorized as producers; they can produce their ownfood. However, not all organisms are capable of photosynthesis. Inthis case, nutrients and the energy stored in them can be acquired byconsuming other organisms. Whether it's a caterpillar eating a leaf, arabbit nibbling on carrots, or you enjoying a garden salad for dinner,the nutrients and therefore energy previously stored within oneorganism is being transferred to another. This type of energy transferoccurs when one organism consumes another. This is why organismsthat obtain their energy from other organisms are categorized as Learn It: Describe the commonfeatures of all lifeforms.consumers. As energy flows from one organism to another, thatenergy is used by organisms to fuel growth, development, andreproduction. The transfer of energy, such as from a carrot to arabbit, is not, however, completely efficient. While some of thatenergy,will be used by the rabbit for growth, development, andreproduction, some of that energy will also be lost to theenvironment in the form of heat.Plants use the energy fromsunlight, CO₂ from the atmosphere,and water to produce nutrients(sugar) through photosynthesis.As energy is transferred someenergy is lost to the environmentin the form of heatEnergy stored within thecarrot is transferred theconsumer (rabbit) as it feedson the carrots.LCOTTIL, DCOCTIOC TIC COTTTTTTTTfeatures of all lifeforms.Nutrients produced throughphotosynthesis provide energy that isused by the producer (carrot) to fuelgrowth, development and reproduction.consumer (rabbit) as it feedson the carrots.Aside from acquiring energy for growth, development, andreproduction, organisms must also be able to sense and respond tochanges occurring both within them and within their environment.For example, the rabbit in the figure has big ears that have a largesurface area and contain lots of blood vessels. If the rabbit's bodytemperature gets too high on a hot day, the rabbit's body canincrease blood flow to the rabbit's ears and, in turn, increase theamount of heat lost through radiation! The process of keepinginternal conditions, such as body temperature, within an optimalrange is called homeostasis. The ability to maintain homeostasis isyet another key feature of all living organisms that increases thelikelihood of survival.
