A tulip, known as "the Viceroy" (viseroij), displayed in the 1637 Dutch catalogue Verzameling van een Meenigte Tulipaanen. Its bulb was offered for sale for between 3,000 and 4,200 guilders (florins) depending on weight (gewooge). A skilled craftsworker at the time earned about 300 guilders a year.

This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or other insects like flies, these are also indicated.
Pollination by insects is called entomophily. Entomophily is a form of plant pollination whereby pollen is distributed by insects, particularly bees, Lepidoptera (butterflies and moths), flies and beetles. Honey bees pollinate many plant species that are not native to their natural habitat but are often inefficient pollinators of such plants; if they are visiting ten different species of flower, only a tenth of the pollen they carry may be the right species. Other bees tend to favor one species at a time, therefore do most of the actual pollination. (Full article...)

The following are images from various plant-related articles on Wikipedia.
Image 11 An oat coleoptile with the sun overhead. Auxin (pink) is evenly distributed in its tip. 2 With the sun at an angle and only shining on one side of the shoot, auxin moves to the opposite side and stimulates cell elongation there. 3 and 4 Extra growth on that side causes the shoot to bend towards the sun.

Image 2The Devonian marks the beginning of extensive land colonization by plants, which – through their effects on erosion and sedimentation – brought about significant climatic change. (from Evolutionary history of plants)
Image 10A late Siluriansporangium, artificially colored. Green: A spore tetrad. Blue: A spore bearing a trilete mark – the Y-shaped scar. The spores are about 30–35 μm across. (from Evolutionary history of plants)

Image 13A banded tube from the Late Silurian/Early Devonian. The bands are difficult to see on this specimen, as an opaque carbonaceous coating conceals much of the tube. Bands are just visible in places on the left half of the image. Scale bar: 20 μm (from Evolutionary history of plants)
