Which best explains the evolution of gymnosperm plants? they evolved along with monocots and dicots. they evolved after the seeded flowering plants. they evolved after the seedless vascular plants. they evolved before the seedless nonvascular plants.

They evolved after the seedless vascular plants.

Explanation:

Seedless vascular plants have no seeds and they reproduce through spores. E.g Ferns.

Gymnosperms are vascular plants with seeds that are naked. E.g.conifers, cycads

Due to evolutionary changes , the gymnosperms evolved from seedless vascular plants. The angiosperms was also believed to evolve from the gymnosperms. This is how some form

of complexity was achieved.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
