A plant that produces seed cones and pollen cones is a vascular plant, and plants that produce seed cones and pollen cones belong to the group of plants known as gymnosperms.
What are gymnosperms?Gymnosperms are a group of seed plants that produce seeds that are not enclosed in an ovary and produce open seeds that are usually borne in cones and include a variety of plant species, including conifers such as pine, spruce, and fir trees, cycads such as palm-like plants, ginkgoes, etc., and the production of seed cones and pollen cones is a vital characteristic of gymnosperms, these seed cones, which are also called female cones, produce seeds that are typically larger and more complex than pollen grains.
Hence, a plant that produces seed cones and pollen cones is a vascular plant and belongs to the group of plants known as gymnosperms.

describe the role of prothrombin in the blood clotting process
Answer:Prothrombin is transformed into thrombin by a clotting factor known as factor X or prothrombinase; thrombin then acts to transform fibrinogen, also present in plasma, into fibrin, which, in combination with platelets from the blood, forms a clot (a process called coagulation).

what is released in the light depended step of photosynthesis?
Answer: Imma say In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. ... The photosystems and electron transport chain components are embedded in the thylakoid membrane.
