Cellular Respiration & Pollination

Cellular Respiration

The multi-step metabolic process by which cells break down glucose and oxygen to generate ATP, releasing carbon dioxide and water as byproducts. The entire process yields a net total of approximately 30 to 32 ATP molecules per molecule of glucose.

Adenosine Triphosphate

The primary energy-carrying molecule used by all living cells to fuel diverse metabolic, transport, and mechanical processes. Often described as the "molecular currency" of the cell, it powers everything from muscle contractions and nerve impulses to DNA replication.

Aerobic Respiration

The cellular process of breaking down glucose in the presence of oxygen to produce a high yield of energy in the form of ATP.

Anaerobic Respiration

the biological process by which cells break down sugars to generate energy (ATP) without using oxygen, produces lactid acid.

Photosynthesis stores energy from the sun in the form of sugars (glucose), respiration releases that stored energy to fuel cellular work.

Photosynthesis vs Respiration

Pollination

The transfer of pollen grains from the anther to the stigma to enable fertilization and plant reproduction. This process is essential for the production of seeds, fruits, and the survival of most plant species.

Anther

The male reproductive structure of the flower.

Stigma

The female reproductive structure of the flower.

Self-pollination

occurs when pollen from a flower's anther falls directly onto the stigma of the exact same flower, or onto another flower on the same plant.

Cross-pollination

The transfer of pollen from the anther of a flower on one plant to the stigma of a flower on a completely different plant of the same species.
