Explanation:
Chargaff contributed in understanding the structure and composition of DNA with his discoveries. He discovered that purine and pyrimidine bases are in equal amounts in a DNA molecule. He also discovered that amount of Adenine base (A) is equal to amount of Thymine base (T). It means that A pairs with T. Since A is a purine and T is a pyrimidine it also implies that purine base pairs with a pyrimidine base. This conclusion can also be arrived by taking in consideration the other base pair which is G (purine) and C (pyrimidine).

Explanation:</h3>
Plants that have specialized vascular tissues that carry materials from one part of the plant to another is a vascular plant. The two types of vascular tissue, xylem and phloem, help in transportation of water, minerals, and the products of photosynthesis throughout the plant. Two types of vascular plants that produce seeds are : Gymnosperms and Angiosperms.
Gymnosperms are plants whose seeds are not enclosed by a fruit. The seeds are unenclosed or present on the surface or leaves. These seed are configured as cones. E.g: Cedar, pine
Angiosperms are fruit-bearing flowering plants with their seeds enclosed inside a fruit or flower. E.g: Apple, Eggplant
