The first of these is nature study. There is no better way of bringing children into contact with plant life than by raising flowers and vegetables in the garden. The children get out of doors, prepare the soil, plant the seed, observe the growth of plants, cultivate them through the season, and finally observe the growth and ripening of the fruit.
We're loving our gardens right now, but we're not quite sure how to look after them.
The hypothesis that plant growth and development is coordinated by plant hormones or plant growth regulators first emerged in the late 19th century. Darwin experimented on the movements of plant shoots and roots towards light [ 162 ] and gravity , and concluded "It is hardly an exaggeration to say that the tip of the radicle . . acts like the ...
Plant domestication is seen as the birth of agriculture. However, it is arguably proceeded by a very long history of gardening wild plants. While the 12,000 year-old date is the commonly accepted timeline describing plant domestication, there is now evidence from the Ohalo II hunter-gatherer site showing earlier signs of disturbing the soil and cultivation of pre-domesticated crop species.

A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
The epicotyl will expand and form the point of attachment of the shoot apex and leaf primordia or "first true leaves". Cotyledons may remain belowground or be pushed up aboveground with the growing stem depending on the plant species in question. In plant physiology, the epicotyl is the embryonic shoot above the cotyledons. In most plants the ...

The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.
