Bacteria are multicellular organisms which lack chlorophyll
(a)True
(b)False

Hint: They are the microscope, single-celled organisms that live in all kinds of environments containing various pigments including carotenes, zeaxanthin, phycobiliproteins, chlorophyll and absorb at around 430 – 620 nm wavelengths.

Complete answer:
Although all bacteria do not possess chlorophyll, some of them i.e. cyanobacteria contain chlorophyll pigment for photosynthesis. They absorb various pigments at various wavelengths.

Additional Information: -Bacteria are classified as prokaryotes, which are single-celled organisms with a simple internal structure that lacks a nucleus, and contains DNA that either floats freely in a twisted, thread-like structure that is called the nucleoid and if present in circular pieces than it is called plasmids.
-Bacterial cells lack membrane-bound organelles, and it shows the sexual mode of reproduction.
-Ribosomes are spherical units in the bacterial cell where proteins are assembled from individual amino acids using the information encoded in ribosomal RNA.
-Bacteria are surrounded by two protective coverings: an outer cell wall and an inner cell membrane.
-Most bacteria multiply by a process called binary fission. In this process, the parent bacterial cell makes a copy of its DNA and grows larger by doubling its cellular content. The cell then splits apart, pushing their duplicated material out and creating two identical “daughter cells”.
So, the correct answer is 'False'.

Note: Bacteria are unicellular organisms that are either present in a cluster of cells or isolated form. These organisms can be distinguished by the nature of their cell wall, by their shapes, or by differences in their genetic makeup.
