Question

Abhi observed the following cell parts of two different cells under a microscope. He recorded his observation in the table given.
$\begin{array}{ccc}\text{Parts of cell}& \text{Cell}{}^{\prime }{\text{X}}^{\prime }& \text{Cell}{}^{\prime }{\text{Y}}^{\prime }\\ \text{Cell wall}& \text{Present}& \text{Absent}\\ \text{Cytoplasm}& \text{Present}& \text{Present}\\ \text{Nucleus}& \text{Present}& \text{Present}\\ \text{Cell Membrane}& \text{Present}& \text{Present}\\ \text{Chloroplast}& \text{Present}& \text{Absent}\end{array}$

Identify 'X' and 'Y'

• A. $\begin{array}{cc}\text{X}& \text{Y}\\ \text{Animal cell}& \text{Plant cell}\end{array}$
• B. $\begin{array}{cc}\text{X}& \text{Y}\\ \text{Plant cell}& \text{Animal cell}\end{array}$
• C. $\begin{array}{cc}\text{X}& \text{Y}\\ \text{Amoeba}& \text{Animal cell}\end{array}$
• D. $\begin{array}{cc}\text{X}& \text{Y}\\ \text{Animal cell}& \text{Ameoba}\end{array}$

Answer 1

The correct option is B

$\begin{array}{cc}\text{X}& \text{Y}\\ \text{Plant cell}& \text{Animal cell}\end{array}$

The characteristics show that ‘X’ is a plant cell and ‘Y’ is an animal cell. This is because plants contain chloroplast. They have a cell wall mainly made up of cellulose and have other cellular parts like cytoplasm, nucleus, cell membrane, etc.
An animal cell lacks a cell wall and does not contain chloroplast. They are dependent on other organisms for their nutrition.
