Where all plant cells originate Differentiate into the three other types of
tissue Dermal tissue Vascular tissue Ground tissue
Found at the end (tip) of roots, and stems.
This tissue causes all plant growth.
The outer covering of the plant
Usually one layer of epidermal cells
the epidermal layer may be protected by: Cuticle Trichomes

Vascular tissue
Ground tissue
The tissue that transports water and nutrients throughout the plant.
Two main types of vascular tissue. Xylem
Water conducting Up
Phloem Food conducting Down

Active transportof mineralsMovement of water by osmosis
Found between the dermal and vascular tissue
In the leaves ground tissue is full of chloroplasts.
The site of photosynthesis in the leaves.
In the stems found with fiber like cells. Help support larger plants in the stems.

Ground tissue
Two main types Taproot: a long
thick, primary root with small secondary roots.
Fibrous: a mass of branched roots with none larger than another.
Uptake nutrients (nitrogen, phosphorus, potassium, magnesium, and calcium)
Active transport of minerals- uses ATP to pump minerals in so that water will follow by osmosis.
Root pressure: caused by specialized cells root pressure keeps the roots from expanding and holding water forcing it to move up towards the plant.
Monocot Dicot
Vascular bundles are scattered without the ground tissue
Vascular bundles are organized in a ring-like pattern.
An optimized structure for carrying out photosynthesis.
Three main parts needed for photosynthesis. Water: transported there by the xylem CO2: diffused in through the stoma with the
use of guard cells. Chloroplast: found in the mesophyll
