Which of the following does not contain chlorophyll?

Fungi do not contain chlorophyll. Unlike algae, bryophytes, and pteridophytes, which possess chlorophyll and can perform photosynthesis to produce their own food, fungi are heterotrophic organisms. They obtain nutrients by absorbing organic matter from their environment rather than synthesizing it through photosynthesis. While algae encompass diverse groups, some species contain chlorophyll and are photosynthetic, contributing to aquatic and terrestrial ecosystems. Bryophytes, such as mosses and liverworts, also contain chlorophyll and conduct photosynthesis, though they lack vascular tissues. Similarly, pteridophytes, including ferns and horsetails, contain chlorophyll and conduct photosynthesis, playing essential roles in forest ecosystems. However, fungi diverge from these groups, lacking chlorophyll and relying on external sources of organic matter for nutrition. This heterotrophic lifestyle allows fungi to occupy diverse ecological niches and perform crucial roles in nutrient cycling and decomposition processes within ecosystems worldwide.
