Document Summary
Water and nutrient absorption 2: root structure and function continuation and connection of cytoplasm. Macronutrients obtained from the soil the proteins, rubisco (50% of the leaf nitrogen) Macronutrients needed in relatively large quantities (up to 0. 1% of dry weight of plant), micro in smaller amounts (in ppm not % dry matter) 96% of a plant is made of carbon, hydrogen, and oxygen. Measured in respect to the least common element in the plant (molybdenum) The element is part of an essential molecule or constituent zinc fingers found on protein that interact with dna (zinc is essential) How fast it grows/yield vs. nutrient concentration measures function. Plasmodesmata = tunnels and pores connecting one plant cell to the next . When something moves symplastically moves through this connection from one cell to another through diffusion; doesn"t have to cross membrane. Not considered nutrients just a basic building factor.
