The correct answer is option I, II and IV.
An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms are a large group and involve shrubs, herbaceous plants, the majority of trees, and grasses. A gymnosperm refers to a plant, which has seeds unprotected by a fruit or an ovary. The gymnosperms comprise of conifers, ginkgo, and cycads.
In the given case, both the sunflower (angiosperm) and gingko (gymnosperm) are seed-producing plants. However, the seeds of a sunflower are safeguarded by a flower or a fruit, while in case of Gingkoes they are not. Also, sunflowers include double fertilization, while the Gingkoes involve only a single fertilization.
The energy released is used for assembly of actin filament with myosin head. when myosin is attached to ATP its heads cannot bind to actin and therefore muscle will remain in relaxed form. However during muscle contraction an enzyme referred to as ATPase hydrolyses ATP to ADP and organic phosphate in the process releasing energy. The energy released changes the position of head of myosin which facilatate its binding with actin. Myosin moves towards m-line dragging actin along with it reducing the length of sarcomere leading to muscle contraction.
