Question

What will happen if? :
a. Stem of cactus does not do photosynthesis.
b. Flowers do not have sticky stigma

Answer 1

Answer:

a) Cacti are plants that have succulent stems, pads or branches with scales and spines instead of leaves. All plants photosynthesize, collecting carbon dioxide through holes in their leaves called “stomata” and converting it into sugar and oxygen. Cacti utilize CAM photosynthesis, a process unique to succulents.

b) The top part of the pistil is called the stigma and is sticky so it will trap and hold pollen. In flowering plants, the flower functions in sexual reproduction. The essential flower parts are the male parts called the stamens and the female part called the pistil.
