When a plant absorbs water in its roots

water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss

a protective outer covering of many plants and animals

moves food throughout the plant

 in the epidermis of a plant that control the opening and closing of a stoma 

The water pressure inside plant cells

the action or fact of forming a united whole

he action or process of adhering to a surface or object

an attractive force exerted upon the surface molecules of a liquid

 a species of plant that has adapted to survive in an environment with little water

a plant that grows in waters of high salinity

 (usually the leaves)

moved into the sieve elements (phloem cells) 

Transport of soluble food material from one plant to another via phloem or xylem

an area of active plant growth, undifferentiated cells divide and form new specialized cells

From germination to the production of seed, within one year, and then dies

 plant that takes two years to complete its biological lifecycle

a plant that lives for more than two years

 at the tip of a plant shoot or root that produces auxin 

where fresh stems, leaves, and other parts of a plant grow after the old parts fall off or dry up

which secondary growth occurs, resulting in increase in stem girth

a plant that has seeds unprotected by an ovary or fruit

A group of flowering plants belonging to the class Liliopsida

characterized by having 2-seed leaves, or cotyledons

green parts that surround and protect the flower bud 

modified leaves that surround the reproductive parts of flowers

Pollen-bearing structure in the stamen

consists of a slender stalk

is the receptive tip of a carpel,

is a long, slender stalk that connects the stigma and the ovary

 is a plant's reproductive structure

female reproductive structures that produce egg cells

the female reproductive part of a flower

consists of the filament and the anther

stage in the life cycle of plants and algae that undergo alternation of generations

multicellular diploid generation found in plants and algae that undergo alternation of generations

is the process by which pollen is transferred to the female reproductive organs of a plant

union of male and female gametes to produce a zygote

a diploid cell resulting from the fusion of two haploid gametes

It consists of a tough coat 

usually becomes the embryonic first leaves of a seedling
