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.
Silkworms are insects. All insects have six legs in the adult stage. Silkworm caterpillars have six real legs, plus five pairs of pseudopods (false legs) on the rear of the body.
