There is much more to living than having a heartbeat. There is much more to life than breathing and the blood flowing through your veins. But not everyone knows this; not everyone sees it this way. You may be living, but are you alive? You are so lucky to be living on this earth, and there are so many people who do not have the clarity of vision to realize that. A human needs the same basic need that every other living form on the planet needs, nourishment, environment and reproduction. A human that can't survive in the natural world must construct an artificial world in which to survive. Humans are multicellular. Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.
An organism can be associated with complete living things such as animals, plants, fungi or microorganisms commonly defined as, any complex thing with properties normally associated with living things. Fortunately, biologists have developed a list of eight characteristics shared by all living things. Characteristics are traits or qualities. Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. Physical growth is an increase in size. Development is growth in function and capability. Both processes highly depend on genetic, nutritional, and environmental factors. As children develop physiologically and emotionally, it is useful to define certain age-based groups.
Trees in a forest, fish in a river, horseflies on a farm, lemurs in the jungle, reeds in a pond, worms in the soil — all these plants and animals are made of the building blocks we call cells. Like these examples, many living things consist of vast numbers of cells working in concert with one another. Other forms of life, however, are made of only a single cell, such as the many species of bacteria and protozoa. Cells, whether living on their own or as part of a multicellular organism, are usually too small to be seen without a light microscope. The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life." Some organisms, such as bacteria, are unicellular, consisting of a single cell.
Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.
Core organelles are found in virtually all eukaryotic cells. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on. Core components include the nucleus, mitochondria, endoplasmic reticulum and several others. All preforming there own individual and unique tasks. With the most important part of an animal cell are the nucleus vacuoles, and mitochondria all of which are enclosed within the cell membrane and immersed in cytoplasm.
REVIEW QUESTIONS:
I know a decent amount before we started writing this task, the steps I took to create this final product what that of combining all of my knowledge of cells and explaining to the best of my abilities. I could of done this assessment better by going into more detail with every sub category of the question asked. I think I did really well in describing all of the questions asked.
