Haustorial – specialized roots that invade other plants and absorb nutrients from those plants. Lignotuber – root tissue that allows plants to regenerate after fire or other damage. Primary – root that develop from the radicle of the embryo, and is normally the first root to emerge from the seed as it germinates.
Also, moving from leaves to roots, e.g. of molecular signals in plants. bathyphyll A specialized leaf produced at the base of a plant, usually when the plant is immature, and which serves to anchor the plant to a substrate; especially notable in the fern Teratophyllum. Contrast acrophyll. beak
This image shows the development of a normal plant. It resembles the different growth processes for a leaf, a stem, etc. On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate.
Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species. [4] The empty cells help retain water in drier conditions.

Thigmomorphogenesis enables plants to adapt their growth and development in response to mechanical stress by modulating structural and physiological traits. Key adaptations include reduced shoot elongation, increased stem thickness, enhanced root anchorage, and changes in flowering time.
The plant uses the rhizome to store starches, proteins, and other nutrients. These nutrients become useful for the plant when new shoots must be formed or when the plant dies back for the winter. [4] If a rhizome is separated, each piece may be able to give rise to a new plant.
