Plant Tissues and Organs

Plant Tissues and Organs. What is a plant?. A plant is a multicellular eukaryote that - has cellulose in the cell walls, stores food in the form of starch, has a cuticle- a waxy, waterproof coating on the stems and leaves. Cuticles help to prevent water loss. Plant Tissues.

  1. Plant Tissues and Organs

  2. What is a plant? • A plant is a multicellular eukaryote that - • has cellulose in the cell walls, • stores food in the form of starch, • has a cuticle- a waxy, waterproof coating on the stems and leaves. Cuticles help to prevent water loss

  3. Plant Tissues • Dermal- surrounds plant • Vascular- transports food and water - Xylem- moves WATER UP - Phloem- flows FOOD (SUGAR) DOWN • Ground- photosynthesis, storage, support • Meristematic- area where growth occurs

  4. Roots • Function: • take in water and nutrients from the soil • Anchor the plant in the soil • Sometimes act as storage (radishes, carrots, etc) • Most grow underground • Contains vascular tissue (xylem & phloem), ground tissue (cortex), dermal tissue and meristematic tissue (root tips)

  5. Root Cross-Section

  6. Stems • Function: • provides support for growth • transports water, food and minerals to and from roots and leaves • Contains all tissue types

  7. Leaves • Function: usually the site of photosynthesis • Increased surface area to allow maximum absorption of sunlight • Contains guard cells & stomata sites of gas exchange

  8. Reproduction • Mosses and ferns use spores • All other plants produce seeds- contain the embryo, food source, and a protective coat • Flowers are the reproductive structure in highly evolved plants • Most flowers contain both male and female reproductive parts (complete flower)
