Question

general characteristic of Monera​

Answer 1

Answer:

Explanation:

Monera are about 1 micrometer in size and complex as living molecules. The Monera cell structure is mostly unicellular and some organisms orm groups or filaments. These organisms are the simplest prokaryotic cell structures.

Answer 2

Kingdom Monera -

Bacteria are the sole members of monera Kingdom.

Main characteristic of prokaryotes-

1. Cell wall -

Cell wall of prokaryotes is made up of peptidoglycan or murein or polysaccharides and amino acids which is type of mucopeptide.

2. Cell Membrane-

A. like eukaryotes the cell membrane of prokaryotes is made up of lipo protein( lipid + protein).

B. The space between cell wall and cell membrane is not at periplasmic space this is space is analogous (functionally same) to lysosome because in this space the digestion of complex substance is done.

3. Cytoplasm -

A. The cytoplasm of prokaryotes lacks membrane bound cell organelles.

B. In prokaryotic cell the nucleus is primitive.

C. The nucleus of prokaryotes is also known as incipient nucleus or genophore or nucleoid or fibrillar nucleus. Nuclear membrane is absent around nucleus. It also lacks nucleolus.

D. Prokaryotes also lacks the true chromosome. Instead of it a false chromosome is present which is made up of ds circular naked DNA + non-histone protein like polymines. This false chromosome coils and forms the chromosomal region which is known as nucleoid.

E. In prokaryotes ribosomes are of 70s type. Ribosomes are site of protein synthesis.

4. Examples -

A. Eubacteria (true bacteria)

B. Blue Green Algae

C. Mycoplasma

D. Archaebacteria etc.
