(a) Hypocotyl is the part of embryonic axis between radicle and cotyledonary node while epicotyl forms the part of embryonic axis between plumule and cotyledonary node.
(b) Coleoptile is a protective covering that surrounds part of epicotyl (the immature shoot). Coleorrhiza is an undifferentiated sheath of monocot seed that covers the radicle and the root cap. 
(c) Integuments are outer cell layers surrounding the megasporangium of an ovule and form seed coat after double fertilization while testa represents the outer layer of seed coat and develops from outer integument of ovule. 
(d) The presistent nucellus present in some seeds is called as perisperm. The fruit wall is pericarp and develops from ovarian wall.

  1. It would appear more linear.
  2. It would show that hemoglobin has a higher PO2.
  3. It would resemble the typical curve in high pH conditions.
  4. It would resemble the typical curve in high PCO2 conditions.
