True berries, such as blueberries and cranberries have seeds inside. The strawberry, however has its dry, yellow “seeds” on the outside (each of which is actually considered a separate fruit). The “seeds” seen on the outside of a strawberry are actually the plant’s ovaries and are called “achenes.”

Correct Option: A

Cottonseed is a non-edible oilseed. Gossypol is a toxic compound found in the cotton plant. This compound is concentrated in the cottonseed but can also be found in other parts of the plant such as hulls, leaves and stems. Gossypol affects mainly the heart and liver.

Mycoplasmas are the smallest and simplest prokaryotes capable of self-replication. Keeping the number of structural elements, metabolic pathways and components of the protein synthesizing machinery to an essential minimum places Mycoplasmas closest to the concept of ‘minimum cells’.

Bacteria are prokaryotes, which, by definition, are cells that don’t possess membrane-bound organelles. Mitochondria are membrane-bound organelles. Cellular respiration, in prokaryotes, occurs within the cytoplasm or inner surfaces of the cell.

Three common sugars (glucose, galactose and fructose) share the same molecular formula: C₆H₁₂O₆. Because of their six carbon atoms, each is a hexose. They are “single” sugars or monosaccharides.
