18 Cards in this Set

  • Front
  • Back

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
