Apart from food, plants need other nutrients like water and minerals.
Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair.
Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants.
7 Where else can plants obtain their nitrogen from?
Plants make their own nitrogen.
B Plants get it from animals.
Plants get it from the soil.
D
Plants have special structures to break down
atmospheric nitrogen.

- Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
