CHARACTERISTICS OF LIFE

A CHARACTERISTICS OF LIVING THINGS

C Levels of Biological Organization

One. Movement - All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun. Living organisms can move or change position, either the whole body or parts of it.

Two. Respiration (Cell) - Cells release energy from food through cellular respiration.

Three. Sensitivity (Respond) - The ability to detect changes in the surrounding environment. Organisms detect and respond to changes in their environment.

Four. Growth - All living things grow. Living things increase in size and develop over time.

Five. Reproduction - The ability to reproduce and pass genetic information onto their offspring. Organisms produce offspring to ensure the continuation of their species.

Six. Nutrition (Metabolism) - The intake and use of nutrients. This occurs in very different ways in different kinds of living things. Living things obtain and use nutrients for energy, growth, and repair.

Seven. Excretion - Getting rid of waste. Organisms remove metabolic waste products from their bodies.

Overview

An educational module outlining fundamental characteristics of life and the structure of cells, aimed at first-year biology students. It covers topics such as movement, respiration, growth, and cell organelles, providing a foundational understanding of biology.

Key Points

1Living things exhibit specific characteristics such as movement, growth, and reproduction
2Cells are the basic unit of life, containing various organelles that perform essential functions
3Biological organization can be described from atoms to biospheres
4The cell theory explains that all living organisms consist of cells and that they arise from pre-existing cells
5Different types of biology, including molecular, organismal, and environmental biology.
