they sure have their own function la. but i mean, for example... the xylem and phloem. the xylem transports water and dissolved mineral salts absorbed by the roots up the stems and to the leaves. while the phloem transports organic substances from the leaves to roots.

the internal structure of the plant is so tiny lar... cant even see it with our naked eyes. and YET!!! they have their own significant roles to play. i believe God made them. He made the plants. yup!

if phloem is taken out, the whole plant gets disrupted. the tissues above it will swell while the below withers. they need each other to function properly just like how our human body function.

i thought it was amazing!! though it's just a tiny plant or maybe some for big trees it amazes me again how God created those plants so that they can release oxygen and we take in those gases. what else can we say then? we are more... much much more complicated than plants!!
