Organ and tissue (lab 2)

• single (mono) cotyledon • long narrow leaf and parallel veins • in the stem, vascular bundles scattered, no structure • floral parts in multiple of 3

• double (di) cotyledon • broad leaf with network of veins • in the stem, vascular bundles in a ring • floral parts in multiple of 4 or 5

centre of the stem

tissue responsible for the transport of water and minerals to the plant (vessels are dead cells)

tissue responsible for the transport the the food to the plant

keeps structure to the plant

protects the plant, has the stomata

responsible for the gas exchange

between the xylem and phloem, and thicken the stem or root of woody plants

plastids containing chlorophyll pigment

plastids containing other pigments than chlorophyll

starch-forming plastids (found on potatoes or carrots)

thin layer of cells with oil or tricons (cell cortex)

palisade long cells and spongy cells

responsible for the photosynthesis

provide structure and support to the cell

cells in the phloem transporting the sugar produced from photosynthesis to the plant

dead cells in the xylem transporting the water and minerals from the roots to the plant

found in cortex or xylem for structure and suport
