Spermatophytes

  • seed-producing plants

  • seeds protect developing embryo and provide it with nutrients

  • no longer need water for fertilization

  • dispersal by wind, insects, and animals

  • heterosporous (ovules and pollen)

  • some can produce wood

  • leaf types can be simple and compound

  • leaf arrangements can be opposite, alternate, or whorled

New cards

Gymnosperms

  • “naked seed” plants that do not produce fruits


3
New cards

Gymnosperms

Cycadophyta

  • corraloid roots with cyanobacteria to fix nitrogen

  • dioeciuos

  • female megasporophylls or ovulate cones (check photo)

  • male pollen cone

New cards

Gymnosperms

Ginkgophyta

  • one species in the whole division

  • fan shaped leaves with dichotomous branching

  • dioecious

New cards

Gymnosperms

Gnetophyta

  • non-flagellated sperm

  • dioecious


6
New cards

Gymnosperms

Coniferophyta

  • evergreen trees, reduced leaves are needles, resin canals

  • non-flagellated sperm

  • monecious (male pollen cone and female ovulate cone on same tree)

New cards

Angiosperms

  • flowering plants that also produce fruits

  • a fruit is a mature ovary that helps with seed dispersal

    • fleshy or dry

  • within the seed is the zygote (2n) and endosperm (3n), formed by double fertilization (2 sperm released from pollen)

  • endosperm provides nutrition to the zygote

  • flower with male and female parts

    • male: stamen with anther and filament

    • female: carpel with stigma, style, and ovary
