denis-greek [22]

Answer:

Certain cell organelles are present only in plant cells like chloroplast and certain only in animal cell like centrioles.

Explanation:

The concept can be explained in three stages:

<u>Organelles only in plant cells</u>- <em>Chloroplast</em> is an organelle which is helpful in photosynthesis. Since animals don't perform photosynthesis, they don't need it. Plant cells also have a <em>cell wall</em> on top of a cell membrane.
<u>Organelles only in animal cell</u>- <em>Centrioles</em> are present in animal cells which help in movement through structures like <em>flagella and cilia.</em>
<u>Organelles present in both plant and animal cells</u>- <em>Ribosomes, nucleus,mitochondria, golgi complex, cell vacuoles, lysosomes</em> are present in both plant and animal cells.
