The Kingdom Plantae Gaiser Life Science Know What do you know about plants as a group? “I don’t know anything.” is not an acceptable answer. Use complete sentences. Evidence After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond. Page # Plantae Information Clarifying ?s characteristics 1. multicellular Living on land In order to live on land, plants must be able to: 1. Obtain water 2. Retain water 3. Reproduce 4. Support weight 5. Transport materials - no roots, exchange of water via active and passive transport Example: moss - internal system of tube-like structures that transport water, nutrients, and food inside the plant Example: trees, daisies, roses non-vascular vascular 2. eukaryotes 3. autotrophes Two type of tubes phloem - transports food (sugar) from leaves to stems and roots xylem - transports water and nutrients from roots to stems and leaves reproduction Seeds - for dispersal Examples: monocotyledons - corn and grass dicotyledons - peas and beans Seedless - spores for dispersal Example: fern Page # Clarifying ?s Leaves’ job leaves Plantae Information Make food from carbon dioxide, water, and sunlight. - contain chloroplasts, which capture sun’s energy to make food (photosynthesis) Leaf parts cuticle - waxy water proof coat on the top side of the leaf - aids in directing water toward the roots stoma - little valve-like structures on the surface of the leaf which allow CO2 to enter and water and oxygen to exit the plant Stem’s job 1. Supports the plant Examples: herbaceous - soft, flexible, and green (daffodil) woody - hard and covered with bark (oak tree) 2. Carries nutrients, water, and food between the leaves and roots Root’s job Impact Summary: FYI: A majority of the human population relies on plants as their main food source. 1. Anchor the plant to the ground 2. Absorb water and nutrients Examples: tap root (dandelions) fibrous roots (tomato plant) Without plants, our ecosystem could not replenish the oxygen that we need to survive!
