1. D (palisade mesophyll is formed by cylindrical and elongated vascular tissues together with very few air spaces, unlike the spongy mesophyll layer)
2. B (germination is when the seed coat(testa) splits open to expose the seed)
3. A (you know that a seed has started to germinate once the radical develops out of the testa)
