Asexual Reproduction: mycelium, Germination, Spore producing structures

Sexual Reproduction: Plasmogamy, Heterokatotic, Karyogamy, meiosis, Germination, Mycelium

Meiosis is cell division

Plasmogamy is the fusion of cytoplasm

karyogamy is the fusion of nuclei

mycorrhizae is a mutualistic relationship with the roots of plants

Mycelium- nutrient absorption, can break down organic matter

Plants also called embryophytes are eukaryotes that belong to the Archaeplastida

Five shared derived characters that separate plants from algae:

-Alterations of generations

-multicellular, dependent embryos

-walled spores produced in sporangia

-Apical meristems

Cones are derived from specialized leaves with sporangia

Female cones produce Ovules, which develop into female gametophyte

Male cones Produce pollen grains which contain male gametophyte

Fertilized ovules develop into seeds, which consist of the plant embryo, a food supply for the embryo and a protective coating

Flowers are modified leaves made up of four layers:

-Sepals- protective structure

-Petals- Showy structures used to attract pollinators

-Stamens- male parts, produce pollen

-Carpels- female parts contain the ovary and ovule

Ovaries develop into fruits

All plants alternate between two different multicellular stages

The haploid gametophyte and the diploid sporophyte
