8 characteristics of life
Responds to stimuli
Reactions to stimuli from inside and outside the body are called responses.
Example of an internal stimulus for rabbit is true hunger. And the rabbit would respond to this stimuli by eating hay.
There are 2 types of stimulus. The external stimulus and the internal stimulus.
Grows and develops
The difference between growth and development is that growth is an increase in a size over time. As they grow, many organisms form new cells and new structures. Development, on the other hand, is the process of natural changes which takes place during the life of an organism.
They have different process of cells. Growth will increase in size, cell division will increase in cells, and cell differentiation which has different cell types, along the process of development and growth.
For example, baby birds cannot fly for a few weeks after born. As they grow, their structures will develop, and will be able to fly. Another example, the transfomation of a catapillar into a buttfly is an example of a development.
Made of one or more cells
Some organisms have one cell only and other organisms have many cells. A single sell is called unicellular and cell that has more than one cell is called multicellular.
Examples, complex tissues are made of more than one cells. Another example is that, bacteria is made of one cell.
Our body is made up of 4 types of body tissue. Connective, epithelial, muscle, and nervous tissue.
Requires energy
Energy is the essential part of our lives. In order to do something, we need energy. Many organisms get energy by taking in food.
For an example, eating food is an example of an energy. When we eat something, we gain energy.
Kinetic Energy, potential Energy, chemical Energy are the types of energy
Displays organization
Levels of organization: atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism
Organization are defined as the hierarchy of complex systems and structures.
Organelle, cells, tissues, organs, are examples of organization.
Reproduces
Orgnisms reproduces in order to continue the next generations. Reproduction must occur for a species to continue to exist.
Asexual and sexual are the two types of reproduction.
For examples, penguins are types of bird, which means that they reproduce by laying eggs.
Maintains homeostasis
Blood glucose homeostasis, Blood oxygen content homeostasis and Extracellular fluid pH homeostasis are some examples of homeostasis.
Humans' internal body temperature is a great example of homeostasis.
Homeostasis is the process that keeps conditions inside the bodies of all organisms stable.
Adaptations evolve over time
Adaptations are inherited changes that occur over time and help the species
to survive.
Structural, physiological, and behavioral are the types of adaptations.
Example of adaptations evolve over time can be animal's fur, and fat to help animals keep warm in cold conditions.
