Fill in the table “Comparative characteristics of gymnosperms and angiosperms”

Criterion for comparison Gymnosperms Angiosperms
The presence of flowers and fruits Have no flowers or fruits Form flowers and fruits
Development of ovules The ovules are enclosed in the cavity of the ovary of the pistil (they lie openly on the scale of the cone) The ovules are enclosed in the cavity of the ovary of the pistil
Pollination method Wind-pollinated Wind-pollinated (as well as with the participation of water, animals and by self-pollination)
Pollination process The organ for catching pollen is the stigma of the pistil (pollen falls directly on the ovules) The pollen falls directly on the ovules (the organ for capturing pollen – the stigma of the pistil)
Structure

conducting

fabrics

Conductive tissues are vessels (tracheids) and complex (simple) arranged sieve tubes Real vessels. Vessels and sieve tubes have a complex structure
Life forms of plants Only woody forms Herbs only (both woody and herbaceous forms)
Features: Most are autotrophs, but heterotrophs are rare (autotrophs only) Most are autotrophs, but heterotrophs are also rare
Fertilization Single Double
Education

seed

Seeds are formed very quickly (slowly, up to 1.5-2 years) and immediately after pollination (the interval between pollination and fertilization can reach 13 months) Seed formation occurs quickly enough – within one growing season
