18 Cards in this Set

  • Front
  • Back


- inside the phloem

- transports minerals + water to the plant through xylem tubes

- provides physical support


- inside the pericycle

- allows minerals, nutrients and water to be passed through to the xylem

- provides physical support


- inside the endodermis

- surrounds the phloem and xylem

- gives rise to branch roots


- inside the cortex

- helps to control the transportation of water + minerals between the cortex and vascular tissues


- 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


- 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


- 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
