chapter 1 organism charictaristics and functions Flashcards
movement
Is the ability of an organism, or part of it, to change position or place. It is easy to see most animals moving, but less easy to see a plant move. A few plants can move parts of themselves quite quickly. In almost any plant, if you look at the cells under the microscope, you can see chloroplasts moving about inside them.8
Respiration
is the way that the organism obtains energy from nutrients - usually from glucose. Respiration is a chemical reaction that happens inside every living cell. all of these chemical reactions including respiration are called metabolism.
Sensitivity
is the ability to detect changes in the environment and respond to them. these changes can be in the internal environment (such as blood temp) or the external environment (such as sunlight.)
growth
the permanent increase in size and dry mass. plants and animals grow by producing new cells.
reproduction
means making more organisms of the same kind.
nutrition
nutrition means taking in materials that provide the chemicals that an animal or plant needs to build cells and use as an energy source.
