ROOT

  • Anchors plant

STEM

  • Holds flower and leaves in place

  • Transports water and minerals up stem

  • Transports food up and down stem

  • Stores food

LEAF

  • Photosynthesis

  • Stores food

  • Asexual reproduction

  • Water transport by transpiration

FLOWER

  • Sexual reproduction

  • Production of seeds

  • Attract pollinators

SEED

  • Inside fruit

  • Production of new plants

  • Dispersal to colonise new areas and avoid competition

PLANT TISSUES

  • Meristematic; area of rapid cell division caused by mitosis to form new tissue

  • Dermal; covering

  • Ground; packing, storage, photosynthetic

  • Vascular; tubes for transport

MERISTEMATIC

  1. AMICAL MERISTEMS

  • Responsible for growth in length.

  • Top of the root in the apical bud

  • Immediately behind the root cap

  1. LATERAL MERISTEMS

  • Responsible for growth in width

  • The middle of vascular bundles

  • It is known as c

  • Produce phloem on the outside

  • Produce xylem on the inside
