Morphology of Flowering Plants

Grittiness of pear fruit is caused by

• sclereides

• raphides

• collenchyma

• dead parenchyma cells

Banana is an example of

• parthenocarpy

The characteristic that does not belong to perigynous flowers is

• Thalamus is disc shaped, cup or flask shaped

• Ovary is superior, other parts are inferior

• Thalamus is hollowed out and is fused with ovary wall

• 50, 2500

• 2500, 2500
