Root zones
- Cell division (apical meristem)
- where new cells are made
- Elongation Individual cells
- elongate.

-
Internode
- segments on stem or branch that are between
- nodes.

-
-
Petiole
- looks like a stem, but isn’t. it connects the
- leaf to the branch.
-
Types of leaf
arrangement
- Opposite- leaves are opposite each other
- Whorled- Leaves are in a circle..
- Alternate- Leaves alternate
-
Epidermis
- outer layer of leaf

Mesophyll
- cell found near the surface of plant leaves
- specializing in photosynthesis
-
2 types of mesophyll in dicots
- Palisade Mesophyll- long cells lined up
- to catch light
- Spongy Mesophyll- has air spaces
- between cells
-
Vascular bundles (veins)

Modular indeterminate growth
- There are repeating units of a plant (stems, nodes leaves) and how many are there
- will vary from plant to plant

Meristem
Where new cells are created
-
Apical Meristems
Produces primary growth (herbaceous) in both roots and shoots
