h) Intercalated discs

Answer 2

Explanation:

a)Tissue present in 'soft parts' of the plants like 'cortex' and 'pith of stem'.- parenchyma tissue

b) 'Long and unbranched' 'extension' of a 'neuron'.- axon

c) A 'component' of 'phloem' formed by an 'end to end' 'fusion of cells' with 'perforated transverse walls'.-sieve cell

d) 'Thickenings' present in 'sclerenchyma cells'.-lignin

e) 'Thin,hair-like projection' present on the 'free ends' of 'cuboidal epithelium'-cilia

f)'Waterproof layer' present on the 'outer wall' of 'epidermal cells'.-cuticle

g)The 'pigment' present in RBC.- hemoglobin

h) 'Zig-zag thickenings' in cardiac muscles.”- intercalated disc
