Introduction: Plant kingdom can be classified into vascular and nonvascular plants. Vascular plants can be further classified as seedless and seed plants. Vascular seed plants are the most widely distributed plants on this planet. Seed plants have a variety of adaptations for the dispersal of their seeds throughout their environments.
Answer to Problem 3MI
Cotyledon- It is a structure of embryo of a seed plant that stores food for the developing embryo.
Cone- It is the reproductive part of cycads and other gymnosperms. It may be male or female.
Annual- It is an anthophyte that completes its life cycle in one year or less.
Biennial- It is an anthophyte that completes its life cycle in two years.
Perennial- It is an anthophyte that lives for several years and produces flowers and seeds every year.
Explanation of Solution
Cotyledon- Vascular seed plants produce seeds. Each seed contains a small sporophyte surrounded by a protective tissue. Seeds have one or more cotyledons that store food or absorbs food for the tiny sporophyte.
Cone- It is the male or female reproductive part of cycads and other gymnosperms. Plants with cones are called gymnosperms. A male cone produces thousands of pollen grains that produce male gametophytes. Female cones produce female gametophytes.
Annual- Based on the life span,
