<h3>⇝ <u>Epidermis</u> :</h3>
Protective tissues includes epidermis & cork. Epidermis is basically a simple permanent tissue, protective in function. It forms one-cell-thick covering over all the parts of plant.
<h3>⇝ <u>Characteristics of Epidermis</u> : </h3>
- Epidermis is formed of living cells, arranged in a single layer.
- In aerial parts, epidermis is covered with a waterproof and noncellular waxy covering called cuticle.
- Cells form a continuous layer, but in leaves epidermis has small openings called stomata.
- Each stoma is guarded by a pair of bean-shaped guard cells which govern opening & closing of stomatal aperture.
<h3>⇝ <u>Functions of Epidermis</u> :</h3>
- Epidermis protects the underlying tissues from mechanical injury, chemicals & infection.
- Cuticle of epidermis protects against water loss & desiccation. It checks the rate of transpiration & evaporation and prevents wilting.
- Stomata in the epidermis of leaves help in gaseous exchange during respiration & photosynthesis.

<span>Out of the following given
choices;</span>
A. The Geiger counter
being used to detect radiation is broken.
B. Two or more samples
we accidentally swapped, causing confusion.
C. A virus contaminated
the reaction in which the probe was made.
D. The human genome
might contain at least one viral gene.
The answer is D. This means that the viral DNA inserted itself
in the human tissue DNA aand became a prophage. A prophage is a latent form of
viral infection where the inserted viral DNA has no interference with the host
cell biochemical processes. The prophage will be present in the daughter cells
of the host cells.
