Question

Rekha and Lekha were given two permanent slides of simple tissues. Identify their slides based on their observations.
$\begin{array}{cc}\text{Rekha's Observation}& \text{Lekha's Observation}\\ \text{(i) Loosely packed cells, thin cell walls and large vacuole}& \text{(i) Cells are tightly packed and form a continuous sheet.}\\ \text{(ii) Large intercellular spaces found between cells.}& \text{(ii) No intercellular spaces between the cells.}\end{array}$

• A. Rekha's slide- Epithelial tissue
  Lekha's slide- Parenchyma tissue
• B. Rekha's slide- Parenchyma tissue
  Lekha's slide- Epithelial tissue
• C. Rekha's slide- Epithelial tissue
  Lekha's slide- Collenchyma tissue
• D. Rekha's slide- Collenchyma tissue
  Lekha's slide- Muscular tissue

Answer 1

The correct option is B Rekha's slide- Parenchyma tissue

Lekha's slide- Epithelial tissue
Parenchyma is a type of permanent tissue. It consists of relatively unspecialised cells with thin cell walls. They are usually loosely packed with large intercellular spaces. Hence, Rekha's slide is of parenchyma tissue.
Whereas epithelial tissues consists of cells that are tightly packed and form a continuous sheet. It has small amount of cementing material between them and no intercellular spaces. Hence, Lekha's slide is of epithelial tissue.
