Question

1. name 3 kinds of organelles that are components of the cell's endomembrane system. briefly describe the function of each component.
2. define cytoskeleton. how does it aid in cell function?
3. distinguish between chromosomes and chromatin.

Answer 1

Question 1

Three kinds of organelle that are components of cell's endomembrane system are:

I. Endoplasmic reticulum

II. Golgi bodies

III. Lysosome

Function of Endoplasmic reticulum: perform various function like synthesis of proteins, folding of protein and transport of protein to the vesicle.

Function of golgi bodies: modification, sorting and packaging of proteins.

Function of lysosome: contain digestive enzyme that digest excess or worn out organelle.

Question 2

Cytoskeleton is a system of fibrillar proteins and tubules in the cytoplasm of many living cell . The cytoskeleton function include give shape to cell, help in the transport of substance inside cell, involved in cell division and in cell signalling.

Question 3

Chromosome	Chromatin
Appear in the metaphase and anaphase	Appear in interphase
Thick, compact and ribbon like structure	Thin long uncoil structure
Allow equal separation of genetic material between two cells	Help in the regulation of gene expression.
