Question

A non-nutritive structure is

• A.
  Tapetum
• B.
  Integument
• C.
  Endosperm
• D.
  Palisade parenchyma

Answer 1

The correct option is B

Integument
Tapetum
Innermost layer of anther is called tapetum, which is made up of multinucleated tapetal cells with dense cytoplasm and provides nutrients to the developing pollen.

Endosperm
Endosperm is a nutritive tissue present in seeds as a food reserve that provides essential nutrients for the growth and development of the embryo. It is formed during double fertilisation.
Integument
Integuments are the protective covering of an ovule. They don't have any reserve food or nutritional functions.

Palisade parenchyma
The mesophyll cells of leaves are arranged into palisade parenchyma and spongy parenchyma. Palisade parenchyma is usually localised in the upper surface of the leaf and is involved in making food for the plants by the process of photosynthesis.
