flowering seed plants

one of the largest families of angiosperms; sunflower family

the flowers in the center of the head of a sunflower

flowers that are often mistaken for the petals of the flower

the bright red structures of a poinsettia that look like petals but are actually leaves

have two cotyledons; broad, flat leaves with branching veins; petals in multiples of 4 or 5; taproot system

one cotyledon; parallel veins; petals in multiples of 3; fibrous root system

used to store food until the seed begins to grow

creeping stem that grows above the ground

leafstalk

thick stem that grows horizontally under the ground providing food storage and a means of vegetative reproduction

tiny openings on the lower epidermis of leaves

transports water and dissolved minerals upward from the roots to the leaves

transports food manufactured on the leaves downward

part of plant that makes and stores food

grows and repairs plants

sap-conducting tissues

protects and waterproofs;not found in herbaceous plants

produces the pollen

stalk holding the anther

organs that produce pollen

elongated, vase-shaped structure in the center of a flower

develops into the stem and leaves

provides nutrition to the growing embryo

the transfer of pollen from an anther to a stigma

develops into the root system

penetrates the soil with relatively little branching

has no main root, but is spread out with very thin roots in a tangled mass

increases the water-absorbing surface area of the root

resemble palm trees

cone-bearing gymnosperms

hip and shoulder

neck,elbow, spinal column

thumb

elbow, knee, ankel, wrist, fingers

the largest of the chest muscles

first term in a scientific name

a group of structures designed to function together as a unit to perform a particular job for an organism

contains the brain

chest area

the part that connects to the spinal cord; controls involuntary muscles

controls balance and coordinates voluntary muscle activity

the building blocks of protein

a molecule of carbon and oxygen atoms attached to a long chain of carbon and hydrogen atoms

bean shaped enlargements of lymphatic tissue

tentative solutions to a scientific problem

the study of fossils

annually moving to a different region

wrote Origin of Species

the first person to devote his entire life to studies with the microscope

developed the scientific classification system

created the idea of uniformitatianism

Father of Genetics

responsible for pasteurization

transmits information to the central nervous system from the senses of sight, hearing, taste, touch, smell, and pain

relay signals from the central nervous system to the other parts of the body

support and insulate nerve tissue

the most important energy producing compounds in the cell; provides most of the energy for living things

complex organic molecules used to build and maintain living cells

should be 1/4 of total calorie intake

important organic substances found in plants and animals and is in the foods made from them

were most of the digestion takes place

aids digestion

primary organ of digestion and absorption

the most plentiful of blood proteins; manufactured in the liver and helos regulate the amount of water in the blood

a special iron-containing blood protein which binds easily to the oxygen and gives blood it's red color

stores oxygen supplied by the blood for the functioning of the muscle

lifts the lower leg and turns it inward

muscles that help you breath

moveable floor of the thoracic cavity

layers of the skin

microscopic network of blood vessels and renal tubules where blood is filtered and the purified liquids are absorbed

the tube that carries the urine from the bladder to the outside of the body

regulates the body's waking and sleeping cycles
