KINGDOM PLANTAE
Description: The leaves have a waxy coat on them to shield against water. The root system, which branches out, provides support and absorbs water. The stem provides support and the petal, flower and bud is the reproductive organ of the plant. Organisms in Kingdom Plantae have cell walls made of cellulose that are used to support the plant. Another characteristic belonging only to Kingdom Plantae is chloroplasts (the organelle that converts light energy into chemical energy). Their ability to convert inorganic matter (carbon dioxide) to organic matter using photosynthesis keeps organisms in kingdom Animalia alive.
Divergent Event: Evidence that plants evolved from green algae; Green algae and plants both have chloroplast with chlorophylls a and b, both have cell walls made of cellulose and both form starch as stored glucose.
Body Plan: Multicellular
Metabolism: Autotrophic (make their own food); photosynthetic chlorophylls a and b allows the plants to make sugars from water and carbon dioxide using the energy available in sunlight
Digestion: IntracellularNervous: None
Circulatory: None, but they have a vascular system.
Respiratory: None, but cells undergo cellular respiration.
Reproduction: Asexual (Ferns) and Sexual (Flowering plants)
Examples:
1. Maple Tree
2. Carnation
3. Yellow Rose
