root, stems, leaves
What are the organs of plant?
dermal, meristamatic, vascular, ground
What are the types of tissues?
epidermal, racheids, vessel elements, sieve tube elements, companion cells, parenchyma, collenchyma, sclerenchyma.
cells that have not yet become specialized for specific functions, such as transport., source of new growth, at edges of plant tips of roots.
Primary Growth; bud
type of plant growth that occurs at the tips of roots and shoots plants grow taller and deeper from tips, apical meristems=____
vascular of cork cambium.
the outer covering of the plant, the skin. protects the plant.
The dermal tissue has ______ covering that is made from ______to prevent water loss.
a single layer of dermal tissue with covers the outside of a plant.
Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body. the bloodstream.
transports sugar and macromolecules that leave to other parts.
sieve tube elements
found in phloem; stacked end to end; have holes so materials can get in and out of the phloem
long tubular cell peculiar to xylem
A specialized short, wide cell in angiosperms; arranged end to end, they form continuous tubes for water transport.
flowering plants that produce seeds in fruit.
tissue that does everything that the vascular, dermal and meristematic dont do.
A relatively unspecialized plant cell type that carries most of the metabolism, synthesizes and stores organic products, and develops into a more differentiated cell type
tissue consists of cells with highly thickened walls that are dead at maturity. It is generally found in the vasucular bundles of stems and as schlerids, individual bunches of cells that give pears and apple cores their gritty texture
type of ground tissue cell with a strong, flexible cell wall; helps support larger plants
Absorbs water and minerals from the ground. Anchors plant in ground.
primary root found in some plants that grows longer and thicker than other roots. ex: carrots
part of a root system in which roots branch to such an extent that no single root grows larger than the rest
outer epidermal layer
covered by tiny root hairs for more surface area and more absorption; greater area to bring in water and nutrients
active transport proteins
The outer epidermal layer contains______________in their cell membranes to pump mineral into plant.
large layer ground tissue; endodermis; Casparian Strips
spongy cortex; ____ encloses vascular tissue; cells are surrounded by ____________
waterproof barriers that force water through cells not around; keep flow one way (b/c osmosis is always high to low).
Central Vascular Cylinder; xylem
water moves into the_______. This is called the _________.
up the stem; root pressure
In the central vascular cylinder, because thewater moves into the xylem; because it cannot go backward, the only place it can go is ___________; this is called___________.
support; holds plant up to the sunlight; transports substance b/w roots and leaves.
water moves by cohesion from roots, 1 way.
in phloem; in two directions
Where are the nutrients transported to?
site of photosyntheis
covered by cuticle; reduces evaporation
specialized ground tissue; lots of chloroplasts; where photosynthesis occurs; veins of xylem and phloem branch.
exterior openings on underside of leaf; site of gas exchange.
surround and control stomata openings.
water escapes through stomata; as water exits, more is drawn up through stem from roots
Stomata open and close to prevent excessive ___________.
