Kingdom Plantae

Kingdom Plantae Complex multicellular eukaryotes Cell walls made of cellulose Undergo photosynthesis

Kingdom Plantae (con’t) Exhibit alternation of generations Sporophyte (diploid) gametophyte (haploid) Life Spans: annual, biennial, perennial

Plant Tissues Dermal tissue Vascular tissue Ground tissue Xylem Phloem Ground tissue Meristematic tissue Plant Tissues Carries water upward from roots to every part of the plant Transports nutrients and carbohydrates produced by photosynthesis

Plants Four basic Needs Sunlight Water and Minerals Gas exchange Transport of nutrients throughout the plant body

Four types of flowering Plants Cladogram Cone-bearing Ferns Mosses 3 Ways that Botanist separate groups of plants Plants evolved from

Diversity of Plants Cone-bearing plants 760 species Ferns and their relatives 11,000 species Mosses and their relatives 15,600 species Flowering plants 235,000 species

Mosses & Their Relatives Bryophytes Mosses & Their Relatives

Bryophytes Also known as mosses

Bryophytes (Mosses & Relatives) Lack vascular tissue (tissue specialized to conduct water and nutrients) so they are low-growing plants found in moist, shaded areas Depend on water for reproduction

Bryophytes (Mosses & Relatives) Recognizable gametophytes Archegonium – female Antheridium – male Produce diploid spores

Three Groups of Bryophytes Mosses Liverworts Hornwort

Common Moss Structures:

Bryophyte Lifecycle Gametophyte carries out photosynthesis because green

Seedless Vascular Plants Ferns – most common True roots/stems/leaves (vascular tissue) Rhizomes Fronds – large leaves Found in wet habitats
