Question

Differentiate between the following pair of words based on what is given in the bracket.
1. Meristematic and permanent tissue (definition)
2. Parenchyma and collenchyma (cell wall)
3. Xylem and phloem (material transport) 4. Ligament and tendon (location)
5. Striated and unstriated muscles (shape of their constituent cells) ​

Answer 1

3. Xylem : transports water throughout the plant body. It is made up of : xylem fibre, xylem parenchyma, vessels, tracheids

Phloem : transports food throughout the plant where needed . It is made up of sieve tubes, sieve cells, companion cells, phloem fibres, phloem parenchyma

4. Ligament : present between bones or in the joints . It is yellow in colour n elastic

Tendon : present between muscles and bones. It is white in colour n is limited flexibility

5. Striated : long, cylindrical, multinucleated, unbranched, alternate light dark bands

Unstraited : long, unbranched, uninucleated , no striations or strips

1. Meristematic tissue is present in growing regions of the plant . ex. at the tips of plant

Permanent tissue is present in non growing regions of the plant body.

cell wall of Parenchyma is thin and consists of unspecialized cells

cell wall of Collenchyma is thickened at the corners
