Concept a: terrestrial plants can be divided into two broad groups. There are two types of vascular plants: gymnosperms, pla(cid:374)t seeds are (cid:374)ot e(cid:374)(cid:272)losed i(cid:374) a(cid:374) o(cid:448)ule (cid:894)i. e. , pi(cid:374)e (cid:272)o(cid:374)e(cid:895) there are referred to as (cid:862)(cid:374)aked seeds(cid:863, wi(cid:374)d polli(cid:374)atio(cid:374) is (cid:373)ost (cid:272)o(cid:373)(cid:373)o(cid:374) , angiosperms. Insect pollination is most common: more abundant than gymnosperms, two basic types: eudicots and monocots . Roots are multicellular organs with important functions: anchoring the plant, absorbing minerals and water, storing organic nutrients. The roots of eudicot plants form a taproot system . The roots of monocot plants form a fi(cid:271)rous root syste(cid:373) . After water and minerals enter the root hair. The endodermis (also k(cid:374)o(cid:449)(cid:374) as the root"s (cid:271)order guard(cid:895) . The waxy casparian strip : symplastic route , apoplastic route .
