Fungi are known to lack which of the following?

Fungi are unique organisms that play critical roles in ecosystems, particularly in decomposition and nutrient cycling. One of the defining characteristics of fungi is that they lack chlorophyll, which distinguishes them from plants. While plants utilize chlorophyll for photosynthesis, enabling them to convert sunlight into energy, fungi do not possess this ability. Instead, fungi obtain their nutrients through absorption, often breaking down organic matter.

Additionally, fungi have cell walls that contain chitin, a feature that further differentiates them from plants, which have cell walls made of cellulose. Fungi also contain nuclei, as they are eukaryotic organisms, meaning their cells have a defined nucleus. They exhibit complex reproductive systems, including both sexual and asexual reproduction methods, which can involve spores, a common trait among fungi.

The choice highlighting the absence of chlorophyll correctly identifies a fundamental difference between fungi and other life forms, particularly plants, emphasizing their role as heterotrophic organisms rather than autotrophs.
