The physics of pollinator attraction

The physics of pollinator attraction SUMMARY: This article focuses on the physical properties of plants that have evolved to help them select the appropriate pollinators and discourage non-pollinators (nectar stealers). The first feature the article addresses is the shape of the cells. Flower petals often have cone-shaped cells to help scatter more light. This gives… Continue reading The physics of pollinator attraction

Chloroplast Division

Chloroplast Division SUMMARY: Chloroplast division in plants is still a fairly unknown topic when it comes to specific cellular/molecular mechanisms. This paper describes, step by step, all the proteins and enzymes involved in helping chloroplasts divide (FtsZ, Min system, ARC6, etc.) It also compares the division of chloroplasts to binary fission in various prokaryotes (FtsZ… Continue reading Chloroplast Division
