Question 1.
Distinguish between the following pairs with reference to what is asked in the brackets. between cells of:
(a) Parenchyma and Collenchyma
(b) Meristematic tissue and Permanent tissue
(c) Blood and lymph (Cellular component)
(d) Bone and cartilage (porosity)
(e) Voluntary and Involuntary muscles (Shape and cellular structure)
Answer:
(a) Differentiate between Parenchyma and Collenchyma
| Parenchyma | Collenchyma |
| (i) Consists of large thin-walled living cells with a single large vacuole
(ii) Intercellular spaces may or may not be present |
(i) Consists of elongated cells having thickening in their cell walls
(ii) Intercellular spaces are totally absent |
(b)Differentiate between Meristematic tissue and Permanent tissue
| Meristematic tissue | Permanent tissue |
| (i) Have the capacity to divide
(ii) Do not have intercellular spaces |
(i) Have lost the capacity to divide
(ii) Have large intercellular spaces |
(c) Blood and lymph
| Blood | Lymph |
|---|---|
| Blood consists of plasma, red blood cells, white blood cells and platelets. | Lymph consists of plasma and white blood cells. |
(d) Bone and cartilage
| Bone | Cartilage |
|---|---|
| Bone is porous. | Cartilage is non-porous. |
(e) Voluntary and Involuntary muscles
| Involuntary muscle cells | Voluntary muscle cells |
|---|---|
| Spindle shaped and small cells. | Cylindrical and long cells. |
| Uni-nucleated cells. | Multi-nucleated cells. |
| Striations are absent. | Striations are present. |
Question 2.
What is the difference between
(a) cell and tissue?
(b) organ and organism?
(c) organ and organelle?
(d) organ and organ system?
Answer:
(a) difference between Cell and tissue
| Cell | Tissue |
| A cell is the structural and functional unit of all living beings.
E.g. epithelial cell |
A tissue is a group of similar cells which perform a specific function.
E.g. nervous tissue |
(b) difference between Organ and organism
| Organ | Organism |
| Several tissues together contribute to specific functions inside the body and constitute an organ.
E.g. stomach |
Several organ systems together constitute the organism.
E.g. human being |
(c) difference between Organ and organelle
| Organ | Organelle |
| Several tissues together contribute to specific functions inside the body and constitute an organ.
E.g. stomach |
Parts of the cell that have a definite function in the cell.
E.g. mitochondria |
(d) difference between Organ and organ system
| Organ | Organ system |
| Several tissues together contribute to specific functions inside the body and constitute an organ.
E.g. stomach |
Many organs act together to perform a specific life process and constitute an organ system.
E.g. digestive system |
