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.
Homework Answers
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. |
