Question

Do bacteria have chloroplasts?

Answer 1

Chloroplasts:

1. It is a membrane-bound organelle also known as plastid, that is present mainly in plant cells and some algae.
2. These chloroplasts house the photosynthetic pigment chlorophyll in sac-like structures called thylakoids.
3. It has an oval-shaped structure with an outer and inner membrane, stacks of thylakoids called grana, and stroma(the cytoplasmic matrix).
4. Chloroplasts are responsible to perform the most important metabolic reaction which is photosynthesis.

Bacteria

1. These are simple unicellular organisms that lack a well-defined nucleus and other membrane-bound organelles.
2. Bacteria and archaea belong to prokaryotes.
3. Escherichia coli, Pseudomonas, Staphylococcus, Lactobacillus, etc are some examples of bacteria.
4. Bacteria do not contain any membrane-bound organelles like chloroplasts.
5. Some bacteria like blue-green algae or cyanobacteria have thylakoid-like structures that store chlorophyll and can perform photosynthesis.
6. These structures are formed by the infolding of the plasma membrane and are not true membraned organelles.
