Bconifers
Cmosses
Dgrasses

Show the answer and working

Answer: C

Mosses: rhizoids, spores.

Trap A Plant classification errors: Bryophytes (mosses): no true roots/vascular tissue. Pteridophytes (ferns): vascular, spores. Gymnosperms: naked seeds in cones (pine). Angiosperms: flowers, seeds enclosed in fruits; monocots (parallel veins, fibrous roots) vs dicots (net veins, tap root).

Trap B Gives the job of a neighbouring structure or stage: Learn structures as pairs of 'name → one job' and contrast neighbours: ribosome makes protein, mitochondrion releases energy; cochlea hears, semicircular canals balance. When two options sit in the same organ or process, ask which one does exactly the job in the stem.

Trap D Uses an everyday idea instead of the biology: Translate everyday words into the textbook definition before choosing. If the only reason an option attracts you is its name or looks, test it against the definition in the stem.

Plant classification errors
Bryophytes (mosses): no true roots/vascular tissue. Pteridophytes (ferns): vascular, spores. Gymnosperms: naked seeds in cones (pine). Angiosperms: flowers, seeds enclosed in fruits; monocots (parallel veins, fibrous roots) vs dicots (net veins, tap root).

Learn structures as pairs of 'name → one job' and contrast neighbours: ribosome makes protein, mitochondrion releases energy; cochlea hears, semicircular canals balance. When two options sit in the same organ or process, ask which one does exactly the job in the stem.
Uses an everyday idea instead of the biology
Translate everyday words into the textbook definition before choosing. If the only reason an option attracts you is its name or looks, test it against the definition in the stem.
Takes one contributing factor as the whole answer
Watch for 'only', 'just', 'mainly'. Ask: is this the MAIN reason, or one contributor? If it would need other things to work (plasma proteins need platelets), it is incomplete.
