Answer 1

a)vascular tissues in pteridophytes
b)notochord in chordata phylum
C) seeds inside fruits in angiosperms

Answer 2

(a) Vascular tissues - pteridophytes

(b) Notochord - chordata phylum

(c) Seeds inside fruits - angiosperms.

Explanation:  

• The pteridophytes are the first group of plants with the ‘vascular tissue’. The vascular tissue consists of the ‘xylem and the phloem’.  

• The xylem is involved in the transportation of ‘water and nutrients’ whereas phloem is used in the transportation of the ‘food material’.  

• The notochord is present in the embryonic ‘stage of the Phylum chordata’. Angiosperms have seeds which are present inside the fruits.  

• The seeds develop from the ovules and the fruits develop from the ‘ovary of the flowers’.
