Which of the following statements regarding protozoa is false?
a) Some protozoa lack mitochondria.
b) Some protozoa contain chlorophyll.
c) Some protozoa are parasitic.
d) Malaria is caused by a protozoan.

Key Concepts

Protozoan Pathogens

Certain protozoa are pathogenic and are responsible for various diseases in humans and other animals. An example of this is the protozoan that causes malaria, emphasizing the medical importance of understanding protozoan diversity and its effects on public health.

Parasitism

Parasitism is a common lifestyle among protozoa wherein they live in or on a host organism, deriving nutrients at the host’s expense. This mode of life is significant not only for the ecological roles protozoa play but also for their impact on the health of host organisms, including humans.

Mitochondria

Mitochondria are key organelles in eukaryotic cells responsible for energy production through cellular respiration. In some protozoa, traditional mitochondria may be reduced or absent, reflecting adaptations to specific environmental conditions such as anaerobic habitats.

Chlorophyll and Photosynthesis

Some protozoa are capable of photosynthesis either inherently or through endosymbiosis with photosynthetic organisms. The presence of chlorophyll in these organisms allows them to harness light energy to produce their own food, a characteristic that highlights the metabolic diversity within protozoa.

Protozoa

Protozoa are a diverse group of single-celled eukaryotic organisms that exhibit multiple metabolic strategies and lifestyles, including free living, parasitism, and symbiosis. They are fundamental to many ecological systems, and their diversity in structure and function makes them an important subject in the study of eukaryotic life.
