|
xylem |
- inside the phloem - transports minerals + water to the plant through xylem tubes - provides physical support |
|
|
Phloem |
- inside the pericycle - allows minerals, nutrients and water to be passed through to the xylem - provides physical support
|
|
|
Pericycle |
- inside the endodermis - surrounds the phloem and xylem - gives rise to branch roots |
|
|
Endodermis |
- inside the cortex - helps to control the transportation of water + minerals between the cortex and vascular tissues |
|
|
Cortex |
- material inside the root - used to store starch - space for minerals and water to flow |
|
|
Root hairs |
- branch off the root - increases the are of the roots - absorbs water + minerals - Increases root pressure |
|
|
Cuticle |
- outer layer of the leaf - reduces amount of water that evaporates from the leaf's surface |
|
|
upper epidermal cells |
- secretes waxy substance called cuticle - protects cell from outside environment |
|
|
palisade tissue |
- gives the leaf physical support - under upper epidermal cells |
|
|
vascular bundle + xylem and phloem tissue |
- in the middle of the leaf - vascular bundle holds together xylem and phloem - the phloem picks up sugars that have been made + delivers them to other cells - the xylem brings water vapour for photosynthesis |
|
|
parenchyma cells |
- spongy - preform photosynthesis - specialized cells |
|
|
lower epidermal cells |
- the bottom of the cell - allows exchange of gases between the leaf and its outside environment |
|
|
guard cells |
- scattered along lower surface of the leaf - change their shape to control the opening and closing of the open spaces in the parenchyma cells - allows gases to move in and out |
|
|
stoma |
- the pores in the lower leaf surface - connected to the openings in between the parenchyma cells - gases are able to be exchanged through the openings |
|
|
Meristematic tissue |
- made of unspecialized cells, that become specialized - can become - vascular tissue - ground tissue - dermal tissue |
|
|
Dermal tissue |
- outermost cover of the plant's organs - protects the plant from its outside environment - controls the exchange of gases and water between the plant and its environment |
|
|
Ground tissue |
- has several functions - ex. some cells preform photosynthesis and some are physical support for the plant |
|
|
Vascular tissue |
- transports nutrients, minerals, water and sugars throughout the plant - provides physical support for the plant |
