Which type of transpiration accounts for the maximum loss of water in plants? MCQ with Answer and Explanation

Explanation:
Cotyledons are seed leaves that store food (starch, proteins, lipids) for the developing embryo and may become photosynthetic after germination. Monocots have one, dicots two. Radicle is root, plumule shoot, seed coat protects.

Explanation:
Lichens represent mutualism where the fungal partner provides shelter, water, and minerals, and the algal or cyanobacterial partner provides food through photosynthesis. Both benefit. Parasitism is harmful to host; commensalism benefits one without affecting the other; predation involves one killing and eating the other. Lichens are bioindicators of air pollution, sensitive to SO₂. This association is obligate.

Explanation:
AUG is the initiation codon and codes for methionine in eukaryotes (formylmethionine in prokaryotes). It signals the start of translation. Arginine codons include CGU, CGC, etc. Alanine is coded by GCU, etc. Glycine by GGU, etc. The genetic code is degenerate, meaning multiple codons can code for the same amino acid, but AUG is unique as the initiator.
