Dicotyledonae
Dicotyledon
Reason correct spelling for biological terms
Reasons: Leaves are net –veined /newt venation /two cotyledons/reticulate venation /tap root system / with leaf petiole.
K1 and K2
Monocotyledonae
Monocotyledon.
Reasons
Leaves are parallel /parallel venation are cotyledon /fibrous roots system/leaf petiole modified into a sheath.
b) Hypocotyl
Rej. Wrong spellings
ii) Protects the plumule shoot tip/first foliage leaves /penetrates through the soil pulls the cotyledon out of the soil
c) Expose of curvature to light auxins to migrate to lower side /opposite side, there is faster growth elongation of cells on the lower side /opposite side hence the stem straightens.
d) Coleoptile /plumule sheath cover or coat are incorrect
e) J1 and J2
f) i) Cotyledons/seed leaves
ii) -Carry out photosynthesis to provide food for the germinating seedlings
-Food reserve store food/ provide food for the germinating seedlings
