2. Cholesterol

3. Phosphoglycerides

4 Proteins

Carotenoid pigments are found in:

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 

The tail of the phospholipid molecule:

In animal cells, lipid-like steroidal hormones are synthesized in the:

1. Nucleus

2. Rough endoplasmic reticulum

3. Smooth endoplasmic reticulum

4. Golgi apparatus
