Question

multicellular organisms have four levels of organization ranging from simplest to most complex. the simplest is the cellular level. one type of cell that can be found in your body is a cheek cell. you are the most complex level: you are an organism. create a model for the five levels of organization from simplest to most complex. describe each level and provide an example of each level in paragraph form.

Answer 1

Answer:

The five levels of organization are:

1. Cells
2. Tissues
3. Organs
4. Organ Systems
5. Organism

Explanation:

Five Levels of Organization:

Cells:

Cells are the fundamental levels of organization of living organisms. They are the basic structural and functional units of life. Cells are composed of different organelles that perform various functions and through division of labor, accomplish different cellular tasks. E.g, muscle cell, neuron (nervous system cells), nephron (specialized kidney cells) etc.

Tissues:

Cells that perform similar functions combine together to form tissues. For example, skeletal muscle tissue, cardiac muscle, vascular tissue etc.

Organs:

Organs are complex structures formed by the combination pf two or more types of tissues that perform specific but related functions. E.g, heart (pumps blood, contains cardiac muscle tissue), brain (conducts nerve impulses, contains neural tissue).

Organ Systems:

Organ systems are a combination of organs that perform related functions and work together to perform specific physiological functions. E.g, circulatory system (contains heart and circulatory system).

Organism:

This is the highest level of organization. An organism is a combination of cells, tissues, organs and organ systems that all work together to perform specific physiological functions.
