Basic Plant Parts
• Roots – absorb water, minerals, and
nutrients
• Stems – transport water, minerals, and
nutrients
• Leaves – capture sunlight and produce
sugar photosynthesis.
Stems
• Consist of a vascular network of cells for
transport.
• Xylem – transports water and minerals
• Phloem – transports food (sugar)
Leaves
• Waxy cuticle on surface
• Palisade Mesophyll – layer of cells beneath
the epidermis that contain chlorophyll
• Vein – contains xylem and phloem
• Stomata – opening on bottom of leaf that
allow gas exchange and water loss
• Guard cells – regulate opening of stomata
• How can a plant modify its leaves:
-to capture more sunlight?
-to receive less sunlight?
-to prevent water loss?
-for protection?

• Animal Dispersal
• Wind Dispersal
• Floating in water
Some animals bury seeds and
they grow into new plants.
Barbs get tangled in animal
fur and carried to new places.
Animals eat fruit, and after digestion
the seeds are dropped in new places.
More barbs and hooks…
Name the dispersal method.
