angiosperm

flowering plant

anther

long stalk at top of a flowers stamen where meiosis produces spores that develop into pollen

bark

all plant tissues outside the vascular cambium: includes phloem, cork cambium, and cork

blade

main part of leaf

bud

undeveloped shoot of a plant

carpel (pistil)

female reproductive organ of a flower

cotyledon

structure in a seed that functions in the storage and transfer of nutrients to the embryo

cross-pollination

a process in which pollen of one plant unites with the egg of a different plant

cuticle

waxy coating on the leaves and other above ground parts of plants that helps the plant retain water.

endosperm

nutrient-storing tissue that nourishes the developing embryo of a plant

fibrous root

type of thin root that makes up a highly branched root system

flower

specialized plant shoot that functions in reproduction: unique to angiosperm

fruit

ripened ovary of a flower

germination

process by which a plant embryo begins to grow

guard cells

1 pair of cells that open and close the stoma of a plant by changing shape, allowing gas exchange with the surrounding air

gymnosperm

plant that bears seeds that aren't enclosed in an ovary

legumes

member of a group of plants that house their own nitrogen-fixating bacteria

monocots

a flowering plant that produces one seed leaf

dicots

flowering plant that produces two seed leaves

nitrogen fixation

process of converting nitrogen gas into ammonia

ovaries

female reproductive structures that produce eggs

ovule

a small body that contains the female germ cell of a plant

petal

A modified leaf of a flowering plant.They are often the colorful parts of a flower that advertise it to insects and other pollinators.

pollen

the fine spores that contain male gametes and that are borne by an anther in a flowering plant

petiole

thin stalk by which a leaf blade is attached to a stem

pollination

transfer of pollen from the male reproductive structure to the female reproductive structure

primary growth

growth in plant length

root cap

A cone of cells at the tip of a plant root that protects the apical meristem.

root hairs

extensions of epidermal cells that increase a plants surface area for water absorbtion

root nodules

legumes' lumps on their roots that contain nitrogen fixing bacteria

secondary growth

pattern of plant growth in which stems increase in width

phloem

the vascular tissue through which food moves in some plants

self-pollination

pollination of a flower by its own pollen

sepal

a leaflike structure that encloses the bud of a flower

stamen

the male reproductive organ of a flower

stem

a slender or elongated structure that supports a plant or fungus or a plant part or plant organ

stomata

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

taproot

primary root found in some plants that grows longer and thicker than other roots

xylem

the vascular tissue through which water and nutrients move in some plants
