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
