radicle

In botany, the radicle is the first part of a seedling to emerge

from the seed during the process of germination.

TERM 2

root hairs

DEFINITION 2

absorbs most of the water from the surrounding soil.A root

hair, the rhizoid of a vascular plant, is a tubular outgrowth of

a trichoblast, a hair-forming cell on the epidermis of a plant

root.

TERM 3

chemistry

DEFINITION 3

study of matter

TERM 4

elements

DEFINITION 4

basic substances that cannot be broken down into other

substances.

TERM 5

nucleus

DEFINITION 5

contained in an atom, has unique number of protons and

same number of neutrons

atomic

number

Number of protons found found in the nucleus

TERM 7

charge

DEFINITION 7

electrons have a charge of -1 protons have a charge of +

Neutrons have no charge

TERM 8

uncharged

atom

DEFINITION 8

number of protons = number of electrons

TERM 9

valence level

DEFINITION 9

outermost occupied energy level of an element

TERM 10

covalent bond

DEFINITION 10

when atoms share electrons (like with H2O) Hydrogen shares

its one electron with O. strongest type of chemical bond

first law of thermodynamics

matter and energy can neither be destroyed or created.

TERM 17

2nd law of thermodynamics

DEFINITION 17

law of increasing disorder(entropy) all reactions increase

energy disorder in a system, which tends to diminish it

availability for cellular use.

TERM 18

water properties

DEFINITION 18

tranparent quality doesn't affect process that require light

(photosynthetic)

expands as it freezes so it is less dense than liquid water

High specific heat (resists changes in temperature)

high surface tension (so some organism can rest on top)

polar molecule (dissolves manyorganic/inorganic substances)

will neutralize acid & base when dissolved together

TERM 19

pH scale

DEFINITION 19

concentration of H+ in solution

range from 0-14 (7 is neutral)

less than 7 acidic

more than 7 basic/alkaline

TERM 20

buffer

DEFINITION 20

A buffer is an aqueous solution consisting of a mixture of a

weak acid and its conjugate base or a weak base and its

conjugate acid.

vascular plants

tissue organized to conduct food and water throughout

structure (both ones that produce and don't produce seed)

tracheophytes

TERM 22

Nonvascular plants

DEFINITION 22

bryophytes lack specialized tissue for conduction food/water

mosses, generally only a few centimeters in height

TERM 23

Angiosperms

DEFINITION 23

plants that produce flowers

TERM 24

gymnosperms

DEFINITION 24

produce seeds without flowers

Mostly trees/shrubs with woody stems
