C is proper. Plants are autotrophs which make their own foodstuff. They also reproduce equally sexually and asexually throughout the alternation of haploid and diploid generations inside their life cycle.

Seedless vascular plants generate embryos that are not protected by seeds. Rather, they reproduce by way of spores. Customers of this team involve ferns, horsetails, quillworts, clubmosses, and spikemosses. These plants used to be termed pteridophytes, but this turned out being an inaccurate group because ferns and horsetails tend to be more carefully related to seed plants than to quillworts, clubmosses, and spikemosses. Seedless vascular plants flourished in the course of the Devonian period and in Carboniferous forests.

Spores are solitary reproductive cells that, beneath the proper problems, will germinate and grow to become a whole new particular person. Bryophyte spores improve into new plants by generating actual copies of their cells – a procedure often called mitosis.

Plants are autotrophs; they develop their very own foods. They are doing so by means of photosynthesis, that is the process of producing nutrients such as sugars from mild Vitality and carbon dioxide. Photosynthesis occurs in mobile organelles referred to as chloroplasts, which incorporate chlorophyll and carotenoids, molecules that soak up light-weight Power and alter it into a usable form.

[37] Early plant anatomy is preserved in cellular detail within an early Devonian fossil assemblage with the Rhynie chert. These early plants had been preserved by getting petrified in chert formed in silica-wealthy volcanic scorching springs.[38]
