Folds in the plasma membrane of bacteria perform most of the same functions as the organelles of eukaryotic cells.
(a)-true
(b)-false

The correct answer will be-false

Explanation:

The folded structure of the plasma membrane was observed in the gram-positive bacteria which were called the mesosomes.

These mesosomes were earlier thought to be involved in the specific functions like cell division, chromosome replication, oxidative phosphorylation.

Later in the 1970s, the research showed that these invaginations of the plasma membrane were produced by the chemical fixation techniques to prepare samples for the electron microscopy and were treated as artefacts.

Thus, false is the correct answer.

on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due
