Can cut flowers perform photosynthesis
The KGB Agent answer: Cut flowers will not photosynthesize, they will transpire
Fresh Cut Flower Preservative Packets.
Besides, youcan raise microscopic and unicellular algae, fresh or salt water algae, aquatic plants,terrestrial plants of all types (grass, flowering plants, succulent plants, orchids,carnivorous plants), mold, mushrooms, lichens, musks, ferns, etc.
To raise these with success you have to reproduce the best possible conditions of thenatural environment where the organism usually lives, to feed it in a suitable manner, andto keep away their natural enemies.
Heres an ugly secret about these packets. Most packets are 5 gram packets which make one pint of solution. Most average vases hold at least one quart of water. If you do not follow the instructions for mixing the vase solution, and end up making a solution that is too weak, you may be providing enough sugar to grow bacteria while not providing enough antibacterial agents to stop the growth. This is a case where clear water with no preservative would be better than an improperly mixed solution. As soon as you notice that the water in your vase has started to become cloudy, its time to dump the water, rinse the stems, give them a clean cut and put them back in the cleaned vase with fresh water. This alone will double the life of your flowers.
It is possible to keep flowers fresh with sugar water ..
They contain a floral preservative that is a food, hydration agent and antibacterial treatment. Used properly, floral preservatives will greatly increase the vase life of your fresh cut flowers.
Food: The food the preservative provides is a sugar. Plants produce sugar through photosynthesis from water, carbon dioxide and sunlight. When a flower is cut from the plant, photosynthesis is no longer an option for the production of sugar. The sugar is needed to continue development of the flower bud into a flower. With this sugar, the flower will perform better in terms of size, color and vase life.

Amaryllis produce small bulbs (clones) which arise from the base plate or ring, at the bottom of the bulb. These will be identical to the "mother"plant. New bulbs may also be grown from seeds, but these bulbs will have characteristics from both the mother plant and the flower of the plant donating the pollen.
All amaryllis are beautiful. 'Aphrodite', 'Red Peacock' and 'Pink Diamond' are probably my top choices. All have large, exquisite flowers and need no staging. There are at least 25 new introductions for 2008, so my list may change. The new cybisters (spider forms) and miniatures are especially eye-catching.

Hydration: While cut flowers will not photosynthesize, they will transpire. That is, water still is taken up by the stems and released into the air through the stomata. A turgid flower is a hydrated flower. A wilted flower is one where the cells do not have their full amount of water. The outside ring of the stem of the flower, just under the bark, is made up of tiny tubes or vessels. This group of vessels or vasculature is responsible for transporting water from the roots, or vase in this situation, to the leaves and flowers. Water sticks to it self and in general will tend to be drawn up the stem by the continual evaporation of water through the pores in the flower and leaves. However, when a flower has been dehydrated through the normal course of post harvest and shipping, the chemistry needs a jumpstart. When the pH of a solution is more acidic, the molecules are more hydrophilic or they tend to stick together more. So, a good preservative includes an agent to lower the pH of the solution, which encourages hydration. This is normally a mild acid such as citric acid.

Sauropods were high grazers that ate tree ferns, cycads, and conifers as their staple. The dramatic radiation of ornithischians in the late Cretaceous coincided with the spread of angiosperms, and their chewing ability continually improved. Insects also dramatically diversified, as did birds and mammals, in an epochal instance of coevolution between plants and animals. Hive insects (bees, wasps, termites, and ants) began their rise when flowering plants did.
