NEET BIOLOGY

Detailed explanation-1: -In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

Detailed explanation-2: -Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP. Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

Detailed explanation-3: -They are eukaryotes, having well defined nucleus and membrane bound organelles. It has mitochondria. Therefore, this is the incorrect option.

Detailed explanation-4: -Prokaryotic cells do not have mitochondria. Most prokaryotes rely on their immediate environment to obtain energy. This process is facilitated by the electron transport chains in the plasma membrane. Mitochondria are only found in eukaryotic cells.

Detailed explanation-5: -Monocercomonoides sp. strain PA203 (later described as M. exilis) is the first eukaryote discovered to lack any trace of mitochondria.
