This web page is an excerpt from a biology textbook that introduces the seven characteristics of living organisms and the hierarchical classification system. It also explains the terms nutrition, respiration, movement, excretion, growth, reproduction and sensitivity with examples and activities.
Chapter 1. Characteristics and classification of living organisms. The stuff you need to know in this chapter: 1.1 CHARACTERISTICS LIVING THINGS Core: Describe the characteristics of living organisms by defining the terms movement, respiration, sensitivity, growth, reproduction, excretion, nutrition Extended:
All living things need food, water, and energy to grow, develop, and carry out their daily life processes. There are two types of organisms based on how they get food: AUTOTROPHS (producers): Get energy directly from the sun and use it to make their own food in a process called PHOTOSYNTHESIS. Examples:
Organisms need materials and energy to grow, develop, reproduce, and stay alive. Metabolism-the combination of chemical reactions in which an organism builds up or breaks down materials as it carries out its life processes. Living things respond to their environment. Stimulus- any environment.
An amazing variety of living things exists on Earth. But living things are all alike in several ways. What does a dog have in common with a bacterium? What does a fish have in common with a mushroom? And what do you have in common with a slimy, yellow blob, known as a slime mold? Read on to find out about the six characteristics that all ...
ferentiate between living and non-living things (movement, reproduction, requirement of a food or energy source and response to one’s environment), we realize that these features are the very characteristics we use to determine if, indeed, life has left that living thing.
All living things are able to sense and respond to stimuli around them such as light, temperature, water, gravity and chemical substances. Learn these seven characteristics of living organisms. They form the basis of the study of Biology. Each one of these characteristics will be studied in detail during the course. Whilst many other
