ANGIOSPERMS AND GYMOSPERMS

ANGIOSPERM

• The flowering plants, are the most diverse group of land plants.
• Most abundant group of plants.
• They contain seeds and fruit.

TYPES OF ANGIOSPERMS.

• They include all plants that have flowers and produce seeds enclosed in a carpel.
• A carpel is a modified leaf that encloses seeds and may develop into a fruit.

ANGIOSPERM REPRODUCTION

• They reproduce by seeds or pollination.
• a mature multicellular organism is produced by new Cells.
• For two plants to cross fertilize, there must be a mechanism for the two gametes to reach each other safely.

GYMNOSPERMS

• The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and Gnetales.
• As land-dwelling plants developed further past ferns.
• Several modifications were developed for water conservation from gymnosperms.

TYPES OF GYMNOSPERMS

• Gymnosperms are seed-bearing vascular plants.
• Cycads, ginkgo, yews and conifers.
• The largest group of living gymnosperms are the conifers.

REPRODUCTION OF GYMNOSPERMS.

• A male cone contains microsporophylls.
• carried by wind to female gametophyte
• To later create more gymnosperm.
