(2) Plant anatomy and Growth

seed leaves produced by embryo that serve to absorb nutrients packaged in the seed until the seedling is able to use it's first true leaves for photosynthesis

flowering plants

• have one cotyledon
• parallel veins
• scattered vascular bundles
• fibrous roots
• petals in multiples of 3

• 2 cotyledons
• net-like veins
• vascular bundles in a ring
• tap roots
• petals in multiples of 4 and 5

a strand of primary conductive plant tissue consiting of the xylem and phloem

where the leave attaches to the shoot

space betweem leaves

main part of the leaf

attaches leaf to node in dicots

attaches leaf to node in monocots

highest point of the shoot

located at junction of leaf and shoot, dormant

supports and absorb water and minerals from soil

extensions of individual cells that absorb

• starch storage
• ex. carrot

1:1

meristem at the tip of a root or shoot that causes the root or shoot to increase in length

a way for the plant to use its esources to get taller, the terminal bud produces a hormone to inhibit the growth of axillary buds

cellulose

created when the plasma membrane presses against the cell wall

• only in plants than need support
• beween plasma membrane and primary cell wall
• made of cellulose and lignin
• strong and hard

• everything inside cell wall
• (plasma membrane, all cytoplasm and all its contents)

stores pigments and waste products

endosymbiosis

photosynthesis occurs

storch storage

contains pigments
