I. 1. Background
Growth is the change that occurs in living things, includingbody size and the increase in the number of cells in an organism.During growth, the organisms undergo a process of increased
activity or maturation of the organ.Growth is influenced by two factors are internal factors and
external factors. Internal factors include genetic and physiologicalfactors. External factors include temperature, fertilizer, pH,nutrients, and sunlight.
Living things need sunlight, including plants. Sunlight iscrucial process of photosynthesis in plants. Photosynthesis is thebasic process in plants to produce food. Foods that are producedwill determine the availability of energy for plant growth anddevelopment.
Sunlight also affects plant growth. Plants that grow in dark
places will grow more quickly, but with the condition of pale, thin,and the leaves do not develop (etiolasi). This occurs due to theabsence of light so as to maximize the function of elongationauksin to plant cells. Conversely, plants that grow in the lightcauses plants to grow more slowly, with relatively shortcircumstances, leaves will breed and also green. This is becausethe sunlight will inhibit the effects of auksin.
Fertilizer of urea (N elements) and vitamins on plant growth,including green beans, will stimulate the formation auksinhormones, which are scattered throughout the apical meristim andkoleotil (growing point) to work more actively in the conduct of celldivision. with active cell division is radikula will grow lengthwise.Urea concentration (N elements) and vitamin B, is determined bythe level of the plant needs for these elements. (N and elements inVit B)
Sunlight and fertilizer affect the growth of green beans.Green beans is one of Leguminosae plants significant in Indonesia.The position of green beans was placed third after soybean andpeanuts. In this proposal will be made an experiment of growth ofgreen bean plants. We will try to conduct experiments influencedby fertilizer and sunlight.

I. 2 Purpose
Based on the background above, the purpose to be achieved
in this experiment are :
1. Conducting experiments of green beans;
2. Observed the growth that occurs in green bean plants
with the influence of light and fertilizer;
3. Noted the growth that occurs in green bean plants.
I. 3 Formulating Problems
Based on the background above, the problem can be
formulated as follows:
1. How green beans will grow in the dark or light?
2. How green bean plant will grow by giving a little fertilizer
or a lot?
I. 4 Hypotesis
Based on the background above, the hypotesis of this
proposal is sprouts that grow in brighter place will be slower than
the growth in dark places because of the growth of sprouts in
bright place blocked by the sunlight the growth of sprouts and the
dark places will grow more quickly because the growth does not
get sunlight (not inhibited by the sun)
I. 5 Method
Based on the background above, variables that will be
observed is the growth of sprouts and the rate of seed germination
of green beans and methods of test used above ground testing
methods. To analyze the data the research methods used are
control variable is land, the amount of water, the size and quality
of green bean seeds, container, the independent variable we use is
the long stem sprouts and the dependent variable we use intensity
of sunlight at the laying of the experiment.

II. 1 Materials
(Dyah Aryulina 2004: 4) Growth begins with the growth of
seeds and fruit. Angiospermae experiencing double fertilization.
Double fertilization produces a zygote and endosperm. Prospective
seeds will grow and develop into seeds. In the prospective seed,
there zygote and endosperm. Zygote will grow and develop into an
embryo. Endosperm grow and develop earlier than the growth and
development of the embryo. Endosperm is rich in food reserves. In
most monocot plants, endosperm contains food reserves that can
be used until the occurrence of germination.
Growth and development of the embryo begins with the
mitotic division and generate basal cell and terminal cells. Basal
cells develop into suspensor. Suspensor serves as liaison between
the embryo and the skin prospective seed, and flow the nutrient
from the parent plant or from the endosperm. Terminal Cells
develop become pro embryo which attached in suspensor.
Cotyledon started to grow to form a bulge on the proembryo also
followed the development of the embryo. Developing embryo to
form the root tip and the tip of the stem.
(http://free.vlsm.org) Division of zygote produces a meristem
tissue which will continue to divide and differentiate.
Differentiation is the change of state of the cells, forming organs
and structures that have different functions. There are 2 kinds of
growth, the primary growth and secondary growth. Primary growth
occurs as a cell result of primary meristem tissue. Primary growth
took place in the embryo the tip of plants such as roots and stems

- Plants grown in the dark has a faster growth than those grown inthe light.- Plants that grow in the light place the leaf color grow more green
and stems more larger, plants that grow in the dark place the leafgrow become yellow and has small or thin stems.
III. 2 Analysis
Based on the results we get from our experiment, it is knownthat plants growing in the light has a shorter size compared withplants growing in a dark place. Because sunlight auksin inhibitinghormones to slow the growth of stems. However, plants that growin the light has a green leaf, because there is food or chlorophyllproduced from photosynthesis. Meanwhile, plants that grow in darkplaces will have yellow leaves and will quickly die. Because there isno supply of food produced by photosynthesis. The data will beanalyzed after a period of time has been set. In this experimentthe time needed is 10 days. The data we will average in
accordance with the provisions
- Average length of green bean plant labeled A is 4,33
cm.
- Average length of green bean plant labeled B is 9,88
cm.
- Average length of green bean plant labeled C is
14.81 cm.

Section IV.
IV. 1 Conclude
We know that sunlight affects plant growth. Plants that grow
in dark places will grow more quickly, but with the condition of
pale, thin, and the leaves do not develop (etiolasi). This occurs due
to the absence of light so as to maximize the function of elongation
auksin to plant cells. Conversely, plants that grow in the light
causes plants to grow more slowly, with relatively short
circumstances, leaves will breed and also green. This is because
the sunlight will inhibit the effects of auksin. And fertilizer of urea
and vitamins on plant growth, including green beans, will stimulate
the formation auksin hormones.
IV. 2 Suggestion
plant which placed in the dark place, it will make grow more
quickly but it will be pale, and has thin stem, also the leaf will not
to be green like the plant which placed in the light place. If we
want our plants to be florish and has green leaves, we can take the
plant in the dark place. But if we want our plants grow high, we
can take it in the dark place.
Section V.
V. 1 Closing
By saying gratitude to God we were able to complete a
biology proposal of growth and development on green bean
plants. However, we realize that our proposal is not perfect. There
are many mistakes to be corrected. Hopefully this biology proposal
will be useful to us all.
