Which of the following are non-green plants?

The non-green plant among the options given is fungi. Plants have chlorophyll, a pigment that gives them their green color, and allows them to make their own food through photosynthesis. However, fungi are not plants and they do not have chlorophyll. Instead, they obtain their food by absorbing nutrients from other organisms or from dead organic matter in their environment. Euglena and Spirogyra are both types of algae and they are green because they contain chlorophyll, like other plants. Angiosperms, on the other hand, are flowering plants, and they also contain chlorophyll, allowing them to photosynthesize and produce their own food. In summary, fungi are the non-green plants among the given options because they do not contain chlorophyll and do not photosynthesize to obtain their food.
