Here are the answers to fill in the blanks, based on biological principles of respiration and cell structure.
1.
Respiration
* *Reasoning:* The definition given (taking in oxygen, burning food for energy, eliminating waste) describes the overall process of cellular respiration.
2.
Lenticels
* *Reasoning:* In hard and woody stems, the outer layer is corky and impermeable. Gas exchange happens through small raised pores called lenticels.
3.
Cytoplasm,
Nucleus, and
Cell Membrane (or Organelles)
* *Reasoning:* These are the three main structural components found inside almost all cells. The cytoplasm is the jelly-like substance, the nucleus holds genetic material, and the cell membrane encloses the cell. *(Note: Depending on your specific textbook, this might also refer to chemical substances like Water, Proteins, and Fats, but structural parts are the standard answer for "substances present inside" in this context).*
4.
Aerobic
* *Reasoning:* "Aero" means air or oxygen. Respiration that requires oxygen is called aerobic respiration.
5.
ATP (Adenosine Triphosphate)
* *Reasoning:* ATP is the primary energy carrier in all living organisms. Energy from food is converted into ATP molecules for immediate use.
6.
Mitochondria
* *Reasoning:* Mitochondria are known as the "powerhouses" of the cell because they are the specific organelles where aerobic respiration takes place.
7.
ADP (Adenosine Diphosphate)
* *Reasoning:* ATP is made by adding a phosphate group to ADP. So, the reaction uses ADP and inorganic phosphate to create ATP.
