Question

Which of the following is found in seed plants?

• A. Complex vascular tissue
• B. Pollen grains that are not flagellated
• C. Retention of megagametophyte within the ovule
• D. All of these are correct

Answer 1

Answer: (D)

All of these are correct

Seed plants have a complex vascular tissue in which xylem and phloem occur in distinct strands called sympodial bundles (vascular bundles), which are embedded in parenchymatous ground tissue. Pollen is a fine to coarse powdery substance comprising pollen grains. Pollen grains of flowering seed plants are usually not flagellated. The female gametophyte (megagametophyte) along with the nucellus (formed from the degenerate megaspores) is found within the ovule of the seed plant.

So, the correct option is 'All of these are correct'.
