Cone in cone structure

Growth cones are the specialized motile structure at the growing tips of developing and regenerating axons and dendrites. They are responsible for directed axon extension, dendritic growth and arborization, and consolidation of the motile tip into the cylindrical axon or dendrite. They were discovered over 100 years ago by Ramon y Cajal who ...

(in botany) A reproductive structure occurring in gymnosperms, known technically as a strobilus. It consists of sporophylls bearing the spore-producing sporangia. Gymnosperms produce different male and female cones. The large woody female cones of pines, firs, and other conifers are made up of structures called ovuliferous scales, which bear ...Distribution of photoreceptors in the eye. Overall, rods outnumber cones by a ratio of 20:1 or greater in the retina. However, in the fovea, the cone density is the highest and is correlated with visual acuity. The probability that a photon will be absorbed by a cone is based on three factors in temporal order:Figure 7.4.2 7.4. 2: A micrograph of a longitudinal section through a yearling Pinus megastrobilus, labeled as follows: A=Ovuliferous scale, B=Megasporaphyll, C=Cone axis.
