(43 cards)

ground tissue system

Front

plant tissues that are neither vascular nor dermal, fulfilling a variety of functions, such as storage, photosynthesis, and support

Back

guard cells

Front

The two cells that flank the stomatal pore and regulate the opening and closing of the pore.

Back

Plasmodesmata

Front

small channels that directly connect the cytoplasm of neighboring plant cells to each other, allowing molecules to pass freely between

Back

Adaptations to flooding

Front

Shallow roots, roots above soil level Air spaces to promote floating If seasonal flooding, many seeds adapted to transport by water

Back

thigmotropism

Front

plant growth in response to touch

Back

pollination

Front

the transfer of pollen from male reproductive structures to female reproductive structures in plants

Back

Central Vacuole

Front

Plant cell component that stores water, nutrients, provides turgor pressure for plant cell to keep its shape

Back

gravitropism

Front

a response of a plant or animal to gravity

Back

day-neutral plants

Front

a plant in which flower formation is not controlled by the photoperiod or day length

Back

dormancy

Front

a condition typified by extremely low metabolic rate and a suspension of growth and development

Back

endosperm

Front

provides nourishment to the developing embryo in angiosperm seeds

Back

mycorrhizae

Front

symbiotic relationships between fungal hyphae and plant roots

Back

abscisic acid

Front

a plant hormone that promotes seed dormancy falling of leaves, and regulates guard cells

Back

root cap

Front

thimble-shaped mass of cells covering and protecting the growing tip of a root

Back

stomata

Front

the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move

Back

lignin

Front

a complex nonpolar polymer that is part of the secondary cell wall

Back

root nodules

Front

swellings on roots; contain nitrogen-fixing bacteria

Back

Adaptations to dry climate

Front

Stomata closure, waxy cuticle Fewer Stomata, stomata in deep pits White trichome hairs reflect sunlight CAM plants do light-independent reaction at night

Back

plant tropism

Front

A plant response in which the direction of the response is related from which the stimulus comes.

Back

photoperiodism

Front

a physiological response to the relative lengths of night and day.

Back

pectin

Front

carbohydrates that constitute the middle lamella between plant cell walls

Back

cuticle

Front

a waxy covering on the surface of stems and leaves that acts as an adaptation that prevents desiccation in terrestrial plants.

Back

xylem

Front

water-conducting tissue, consisting primarily of tracheids and vessels

Back

germination

Front

the process whereby seeds or spores sprout and begin to grow

Back

long-day plants

Front

a plant that flowers only when the light period is longer than critical length

Back

root

Front

an organ in vascular plants that anchors the plant and enables it to absorb water and minerals from the soil

Back

transpiration

Front

the passage of water through a plant and evaporation to the atmosphere because of differences in water potential, cohesion and adhesion

Back

Topsoil

Front

Made of minerals and organic material (humus)

Back

root hairs

Front

tiny hair-like extensions that increase the surface area of the root allowing it to absorbs more water and nurtients

Back

lateral meristem

Front

a meristem that thickens the roots and shoots of woody plants.

Back

epidermis

Front

the dermal tissue system of non-woody plants, usually consisting of a single layer of tightly packed cells.

Back

fruit

Front

a mature ovary of a flower. the fruit protects dormant seeds and often aids in their dispersal

Back

vascular tissue

Front

plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body

Back

phototropism

Front

growth of a plant shoot toward or away from the light

Back

apical meristem

Front

embryonic plant tissue in the tips of roots and the buds of shoots. The dividing cells of an apical meristem enable the plant to grow in length

Back

cotyledon

Front

a seed leaf of an angiosperm embryo. Some species have one cotyledon, others two.

Back

flower

Front

reproductive organ of angiosperm plants

Back

pollen grain

Front

in seed plants a structure consisting of the male gametophyte enclosed within a pollen wall

Back

shoot system

Front

the aerial portion of a plant body, consisting of stems, leaves, and flowers.

Back

trichomes

Front

hair-like protuberances, which include hairs, thorns, root hairs

Back

Advantages for land plants

Front

At first, no predators, Lots of Light- especially red wavelengths (they don't get down very far into water), Lots of CO2

Back

phloem

Front

vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant

Back

short-day plants

Front

a plant that flowers only when the light period is shorter than a critical length

Back
