DENDROLOGY

Detailed explanation-1: -Male and female flowers of gymnosperms are borne on different sporophylls of the same plant. Explanation: Gymnosperms are flowerless plants producing naked seeds. In gymnosperms, spores are produced in sporangia of sporophyll.

Detailed explanation-2: -In gymnosperms, a leafy green sporophyte generates cones containing male and female gametophytes; female cones are bigger than male cones and are located higher up in the tree. A male cone contains microsporophylls where male gametophytes ( pollen ) are produced and are later carried by wind to female gametophytes.

Detailed explanation-3: -A plant which bears both male and female flowers on the same plant is known as a monoecious plant, e.g., maize and castor .
