This tutorial introduces photosynthesis
Well, the process of producing food with the help of light energy remains the same for both aquatic and land plants.

In the potato plant, lateral buds at the base of the stem produce shoots which grow laterally at first and then down into the ground. These are comparable to rhizomes, as they are underground stems with tiny scale leaves and lateral buds. They do not swell evenly along their length with stored food.
Plants such as the strawberry have a very short stem, called a rootstock, with thin scale leaves,. Foliage leaves and flowers grow from the buds in the axils of the scale leaves. Some of the lower buds produce shoots which grow horizontally over the surface of the ground and bear scale leaves and buds. The terminal buds of these runners turn up and produce daughter plants some distance away from the parent, the new plants developing adventitious roots. Later, the runner shrivels away. The runner does not store food but conducts it from the parent plant to the daughters, until they are well developed.

Blackberry stems form a rather different type of runner in which the main shoot forms the new individual. When the growing end of a shoot arches over and touches the ground, the terminal bud curves up, producing a new shoot which soon develops adventitious roots.
Food made in the leaves passes to the ends of these rhizomes, which swell and form the tubers we call potatoes. Since the potato tuber is a stem, it has leaves and lateral buds; these are the familiar ‘eyes’. Each one of these can produce a new shoot in the following year, using the food stored in the tuber. The old tubers shrivel and rot away at the end of the season

The researchers essentially just introduced Moorella thermoacetica to a cadmium salt and amino acid, cysteine. The bacteria combine the sulfur atoms in the cysteine with the cadmium to create little light absorbers, cadmium sulfide. M. thermoacetica normally creates acetic acid from carbon dioxide through its own respiratory process. But the cadmium sulfide they made in the experiment allowed them to supercharge the acetic acid production process using energy harvested from the sunlight. The team presented their creations at the 254th National Meeting & Exposition of the American Chemical Society (ACS) this week.
Reading science news all day can be real grim. Animals are dying, the climate is changing, the nuke’s a coming, yadda yadda. But sometimes (in fact, often) scientists do something that’s just neat, important, and won’t keep you up at night—that is, if you’re cool with photosynthesizing cyborg bacteria.

CHAPTER 13 – PHOTOSYNTHESIS IN HIGHER PLANTS – Biology …
The annual cycle of a rhizome is similar to that of a corm. In late spring/early summer, food from the leaves passes back to the rhizome, and a lateral bud uses it, grows horizontally underground, and so continues the rhizome. Other lateral buds produce new rhizomes which branch from the parent stem. The terminal buds of these branches curve upwards and produce new leafy shoots and flowers. Contractile, adventitious roots grow from the nodes of the underground stem and keep it at a constant depth.

The results are obviously cool, but the researchers that others are devising synthetic photosynthetic systems and their bacteria might not be the winning option. “There are so many different designs of these systems coming out and really we’ve only begun to explore the different ways we can combine chemistry and biology,” Kelsey Sakimoto at Harvard University told them.
Notes from chapter 10 of the AP Biology book covering photosynthesis
In plants with rhizomes, the stem remains below ground but continues to grow horizontally. The old part of the stem does not die away as in bulbs and corms, but lasts for several years. In the iris, the terminal bud turns up and produces leaves and flowers above ground. The old leaf bases form circular scales round the rhizome, which is swollen with food reserves. Lateral buds grow into new rhizomes.

Rose plants grown from seed would produce a wide variety of plants, only a few of which would retain all the desirable features of the parent plant. Most of them would be like wild roses. Similarly, most of the apple trees grown from seed would bear only small, sour ‘crab-apples'. By taking cuttings and making grafts, the inbred characteristics of the plant are preserved and you can guarantee that all the new individuals produced by this kind of artificial propagation will be the same.

The formation of one corm on top of another tends to bring the successive corms nearer and nearer to the soil surface. Adventitious roots develop from the base of the new corm. Once these have grown firmly into the soil, a region near their junction with the stem contracts and pulls the new corm down, keeping it at a constant level in the soil. Wrinkles can be seen on these contractile roots where shrinkage has taken place. Bulbs also have contractile roots which counteract the tendency in successive generations to grow out of the soil.
