Question

Compare the hibiscus and spider lily pollen grain structure

Answer 1

Pollen grains are the male gametes in plants. It is present on the anthers. Pollen grains finds its way to the ovule by the process of pollination. The structure of pollen grains vary from one species of flower to another.

Here we will discuss the pollen grain structure of Hibiscus and Spider lily.

Hibiscus:- The pollen grain of hibiscus are microscopic in size, ranging in diameter from less than 0.01mm to a little over 0.5 mm . The outer covering of pollen grains, called the pollen wall, is often sculpted in different shapes.

Spider lily:-The structure of pollen grains vary from one species of flower to another. The spider lily have circular pollen grain. However, the atomic structure of pollen grain of hibiscus represents the Buckminster fullerene but is not shown in spider lily.

Answer 2

The hibiscus and spider lily both have circular pollen grain.

Explanation:

• Pollen grains are the male reproductive cells of flowering plants.

• Pollen grains are microscopic in size, ranging in diameter from less than 0.01 mm to a little over 0.5 mm.

• A mature pollen grain has a two-layered wall-the outer exine and inner intine. mitotically to produce two functional male gametes.

• The structure of pollen grains varies from one species of flower to another.

• The hibiscus and spider lily both have circular pollen grain. The pollen grain contains the generative nucleus and a tube nucleus.

• Pollen grains are sterile to the stigma of the same flower.
