Prokaryotic cells have something unique in the form of:

1. Inclusion bodies

2. Plasmids

3. Cell wall

4. 70 S ribosomes

Gas vacuoles allow cyanobacteria to:

1. Store carbon dioxide for assimilation
2. Control their buoyancy
3. Provide anaerobic conditions to nitrogenase
4. Eliminate toxic ammonia

The lipid component of the plasma membrane mainly consists of:

1. Triglycerides

2. Cholesterol

3. Phosphoglycerides

4 Proteins

Carotenoid pigments are found in:

I. Chloroplasts

II. Chromoplasts

III. Leucoplasts

1. Only I

2. Only I and II

3. Only II

4. I, II and III

Microbodies, which help to convert stored lipids into carbohydrates so they can be used for plant growth, are known as:

1. Peroxisomes

2. Sphaerosomes

3. Glyoxysomes

4. Lysosomes

Ribosomes are produced in

1. Nucleolus

2. Mitochondria

3. Cytoplasm

4. Golgibody

All the following are the part of a eukaryotic cell endomembranous system except:

1. Vacuole

2. Lysosome

3. Golgi complex

4. Mitochondria

A feature unique to prokaryotes would be:

1. A cell wall not made up of cellulose

2. An extrachromosomal plasmid DNA

3. A cell membrane of peptidoglycan

4. Presence of inclusions

Chromatophores are:

1. present in liopolysaccharide layer of gram negative bacteria

2. colored pigments present in fluorescent bacteria

3. vesicles that store pigments in prokaryotic cells

4. extensions on membrane in cynobacteria
