EVERYDAY SCIENCE

Detailed explanation-1: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.

Detailed explanation-2: -Eukaryotic cells contain several membrane-bound structures, or organelles, which are specialized cellular subunits that carry out specific cellular functions. The nucleus is surrounded by the nuclear membrane, also called the nuclear envelope, which protects the genetic material stored inside.

Detailed explanation-3: -Bacteria are prokaryotic and unicellular organisms. The cell wall of bacteria is made up of peptidoglycan layer, and they lack membrane-bound organelles. The bacterial cell has a simpler organisation of structure. Hence, the given statement is false as bacteria are not eukaryotic organisms.

Detailed explanation-4: -Most prokaryotes are small, single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm.
