KINGDOM PLANTAE Mosses and Ferns

Characteristics of ALL plants 1. Have cellulose in their cell walls 2. Capable of photosynthesis 3. Body is differentiated into tissues, organs and systems (complex)

KEY VOCABULARY TERMS ABOUT PLANTS Epiphyte - A plant that grows upon another plant (ex. tree) non-parasitically Hydrophytes (Aquatic Plants) - Plants that have adapted to living in or on aquatic environments Mesophytes - Terrestrial plants which are adapted for neither dry nor wet environments Xerophytes - Plants that can survive in an environment with little available water (e. g. cacti)

Algae Characteristics of Algae – • • Aquatic, possess chlorophyll, body not differentiated into root, stem or leaf, sexual reproduction by swimming gametes Examples of Algae - Green, red and brown seaweed, spirogyra

Plantae Bryophyta (mosses Filicinophyta (Ferns) Coniferophyta (Pines) Angiospermophyta (Flowering Plants)

Bryophyte Plants who’s body not differentiated into root, stem and leaves such as mosses Characteristics of Bryophyta – • Terrestrial, • May have stem and leaf like structures • Well defined sexual reproduction • Has chlorophyll • Plant body not differentiated into root, stem and leaves • No vascular tissues • Live in damp shady places

MOSSES (Type of Bryophyte) Examples of Bryophyta - Mosses Characteristics of Hepatica (Liverworts) – Rhizoids are unicellular, simple sporophyte with no chlorophyll Examples of Liverworts - Pellia

Advantages and Disadvantages of Mosses 1. Agents of soil formation due to the role in weathering of rocks 2. Sources of food for insects and other organisms 3. Conserve and decorate the environment 1. Germinate and grow on the walls of buildings and destroy the structures 2. If in excess, they can pollute the environment

Division Filicinophyta (Pteridophyta) (Ferns) Characteristics of Pteridophyta – • Terrestrial • highly differentiated with body and stem, leaf and root structures • high degree of internal tissue differentiation • possess chlorophyll • well defined sexual reproduction • found in water, arid country, or as epiphytes in trees Examples of Pteridophyta - Ferns

Distinguishing Characteristics of Ferns 1. Coiled, bud barring leaves that bear spore producing structures called Fronds 1. Have clusters of spore producing structures called Sori (Plural) or Sorus (Single) 1. Have TRUE leaves, stems, and roots

Advantages and Disadvantages of Ferns 1. Significant ground NONE LISTED… cover plants in CAN YOUR GROUP moist areas THING OF ANY? ? 2. The typical plant benefit of photosynthesis
