General characteristics multicellular eukaryotes cell walls made of cellulose carry out photosynthesis
Plantae Life cycle alternation of generations gamete-producing plant, also known as gametophyte, is haploid. spore-producing plant, also known as sporophyte, is diploid.
Plantae What plants need to survive sunlight water and minerals gas exchange movement of water and nutrients throughout the plant photosynthesis
Plantae photosynthesis formula –6CO 2 + 6H 2 O C 6 H 12 O 6 + 6 O 2 2 main reactions 1. light reaction- These reactions split water molecules, providing hydrogen and an energy source for the Calvin cycle. Oxygen is given off. 2. Calvin cycle- the series of reactions that form simple sugars (glucose) using carbon dioxide and hydrogen from water.

Four types of Plants Bryophytes –Mosses and their relatives Pterophytes –Ferns and their relatives Anrthophytes –flowering plants Coniferophytes –cone-bearing plants Plantae
Bryophytes –the non-vascular plants need water for reproduction; can draw up water only a few centimeters from the ground Plantae
Bryophytes groups Mosses –wet/moist habitats and poor soils –no true roots - rhiziods instead –sperm are produced in antheridia and eggs in the archaegonia. Liverworts –reproduce asexually by means of gemmae. Hornworts Plantae
Seedless Vascular Plants contain vascular tissue, a type of tissue that conducts water and nutrients through the body of the plant. xylem is the vascular tissue that carries water upward from the roots to every part of the plant. phloem transports nutrients and carbs (food) produced by photosynthesis Plantae
Seedless Vascular Plants structure roots –underground organs that absorb water and minerals leaves –photosynthetic organs veins –vascular tissue made of xylem and phloem stems –supporting structures that connect roots & leaves, carrying water and nutrients Plantae
Seedless Vascular Plants types Club Mosses: small plants in moist woodlands Horsetail: also known as Scouring rush. –stems contain crystals of abrasive silica. Ferns –have underground stems –diploid sporophyte - stage is dominant. This stage produces haploid spores. Plantae

Seed plants contain vascular tissue the two types include: gymnosperms bear their seeds on the surface of cones and angiosperms, also known as flowering plants, bear their seeds within a layer of protective tissue do not require water for fertilization adaptations that allow seed plants to reproduce without water include flowers or cones -, the transfer of sperm by pollenation, and the protection of embryos.

Seed plants Gymnosperms means “naked seed” –gnetophytes, cycads, ginkoes, and conifers –conifers are mostly known as “evergreens”. gnetophytes cycads Plantae
