Why plants grow towards the light. 1  Botany: A Stem's 'Sense of Self' Contributes to Shape. 2  Scientists Discover C4 Photosynthesis Boosts Growth by Altering Size, Structure of Plant Leaves, Roots. 3  Cellulose Goes Off the Rails: Without Microtubule Guidance, Cellulose Causes Changes in Organ Patterns During Growth.
Tasting hairs on the legs of a roach can not only help it determine a food source, but help it avoid pesticides as well. Glycocides -- poison baits mixed with glucose -- were traditionally used to dose the sweet-loving cockroach with lethal toxins.
Hissing Cockroachs have three sets of legs attached to their thorax. Cockroaches are insects. Because of their large size they are a good tool to help point out the important insect features: head, thorax, abdomen, antennae, 6 legs, and spiracles (holes in the body for respiration).
