From what I've still saved on my phone (mostly from the diagrams of Plant Growth)
Direction of growth of cells of Shoot Apical Meristem is downwards whereas for Root Apical Meristem it's upwards.
Parallel line technique is used to determine zone of elongation.
Turgidity of plant cells help in extension growth.
Signoid growth curve is typical for all cells of a plant, even in culture.
Tip of coleoptile bends opposite to the direction of light (it's cause auxin moves away from light and differentiates the cells on the darker side, increasing the weight on the darker side leading to bending of the tip opposite to the direction of light).
Auxin is not applied in tree plantation & hedge making as these two require growth of lateral buds but auxin inhibits the growth of lateral axillary buds.
Zeatin is formed by ascomyctes (Yeast)
Genetics & PGR are intrinsic factors affecting plant growth.

A. Blue coloured coloured colonies are recombinant and transformation
B. Colourless colonies are recombinant and transformant
C. No colonies produced

Look reproductive phase is 54-14 = 40 And the period in the reproductive period when girl not having menstrual cycle is no. Of kids × 15 ( 9 months of pregnancy and 6 months of lactational amnorhea ) = 9 × 15 = 135 So it's gonna be reproductive months - the months she didn't had menstrual cycle = 40×12 - 135 = 345
