Solution:

  1. Angiosperm differ from gymnosperm in having specialised structure to cover seeds as in gymnosperm the seeds are naked
  2. In angiosperm the seeds are enclosed by fruits while in gymnosperm the seeds are not covered by any fruit wall and remain exposed
  3. Double fertilisation where fertilisation of egg cell and two polar nuclei (diploid secondary nucleus) take place at same time is found in angiosperm where it is absent in gymnosperm
  4. In angiosperm, there is presence of xylem vessels while xylem tracheids are present in gymnosperm
  5. In gymnosperm seeds are formed through cones while cones are absent in angiosperm
  6. Endosperm is haploid in gymnosperm while it is triploid in angiosperm
  7. Angiosperm are found as herbs, shrubs and trees while gymnosperm are mostly found as trees
  8. Angiosperm are pollinated by insects while gymnosperm are pollinated by wind
  9. Companion cells are found in angiosperm while there is absence of companion cells in phloem in gymnosperm
  10. Angiosperm are evergreen or deciduous but gymnosperm are mostly evergreen trees

Knowledge Booster:

  1. Study of gymnosperm are called gymnospermology
  2. Angiosperm are divided into two classes called monocot and dicot
  3. In xylem angiosperm contain vessels, xylem fibres and xylem parenchyma and in phloem it contain sieve tube, companion cells, phloem fibres and phloem parenchyma
  4. In xylem gymnosperm contain tracheids, xylem fibres and xylem parenchyma while in phloem it contain albuminous cells, sieve cells, phloem parenchyma and phloem fibres
  5. Gymnosperm and Angiosperm are called seed bearing plants or spermatophyta
