#Question id: 5641

The fate map of the arabidopsis embryo at the heart stage indicates that:

#Unit 5. Developmental Biology

  1. The primordia of the leaves, stems, and roots have already formed

  2. The three germ layers that will give rise to roots, stems, and leaves have formed

  3. A fate map the regions that will give rise to laves, stems, and roots can be drawn, although the cells are still undifferentiated, as is the case with the animal blastula

  4. Although none of the adult structures have formed, the regions that will give rise to the meristems, which will in turn give rise to adult structures, can be identified

#Unit 6. System Physiology – Plant

plants such as maize whose vascular tissues are surrounded by two distinctive photosynthetic cell types In this anatomical context, the transport of CO2 from the external atmosphere to the bundle sheath cells proceeds through five successive stages such as;

a.) Fixation of the HCO3 − in phosphoenolpyruvate by PEP Case in the bundle sheath cells

b.) Transport of the four-carbon acids (malate or aspartate) to mesophyll cells that surround the vascular bundles

c.) Decarboxylation of the four-carbon acids and generation of CO2 which is then reduced to carbohydrate via the Calvin–Benson cycle

d.) Transport of the three-carbon backbone (pyruvate or alanine) formed by the decarboxylation step back to the mesophyll cells

e.) Regeneration of phosphoenolpyruvate, the HCO3 – acceptor
