The word "roots" is correct and usable in written English.
It can be used as a noun or a verb to refer to the origin of something or the act of establishing a connection with something. For example, "He went back to his roots and planted a vegetable garden in his backyard."
Growth of seedlings with and without bacteria on nutrient-free agarose showed that bacteria stimulated roots to form root hairs and trigger the root gravitropic response where roots grew downward into the medium (Tables 1– 3).
Your fern may have sections of thick, fleshy roots with fine roots growing from them.
Local roots: Fredricks grew up in Brentwood and attended Palisades High School.
Without bacteria, the majority of the seedling roots grew on the surface of the agarose, and any roots that grew downward into the agarose lacked root hair development.
Furthermore, the mutant crown roots extended randomly, whereas the WT crown roots grew in the direction of gravity.
Plant roots grew from tubes into the solution.
At the end of the growth period, root length density (cm cm−3 of substrate) could not be appropriately measured because, as shown in Fig. 2, roots grew into the nylon sheet lining the rear of the rhizobox, making it impossible to satisfactorily harvest roots.
Thereafter, the two roots grew vertically at similar rates, as though they were one root.
It might well be that more fine roots grew into cast microsites but could not be detected by measuring root biomass only.
When the engineered hairy roots grew to about 5 cm, genomic DNA was isolated from hairy root samples by using DNA pure Plant Kit (Tiangen Biotech Co., Ltd, Beijing, China), which was used in PCR analysis for detecting the presence of AaPMT and/or AaTRI in transgenic hairy root cultures (Table 3).
The roots mentioned in the preceding section were all aerial roots, and aggregations with or without fusions took place mostly in the vertical plane, as the roots grew downwards toward the soil.
