Akey difference between green algae and land based plants is that

Green Algae can either be unicellular ( single-celled) or multi-cellular while land bases plants are typically multi-cellular organisms ( made up of many cells)

Explanation:

A key difference between green algae and land based plants is that; while plants are typically multi-cellular organisms, Algae can either be unicellular     ( single-celled) or multi-cellular.

Thus the key difference between green algae and land based plants is their complexity. Algae are simple organisms while plants are complex, with several specialized structures.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
