GROWTH AND DEVELOMPENT
The definition
Growth is the process of size the
increase (volume, length and mass)
Development is the of becoming
mature
Factors that influence the growth
and develompment
External factors:
• Water and minerals
• Nutrition
• Air
• Weather
• Temperate
• Light
Internal Factors:
• Gens
• Hormon (endocrine)
Differentiate of Growth and
Development
Growth
Growth is change of organism measure because
increasing of cells in every organism body which can
be measured by measuring tools or have the
quantitative value. Or change of organism measure
from small to large.
Example of Growth
 Plant stem that has length 2 cm become 5 cm
 Baby which weight 5 kg turn on into 6,5 kg
 When we will measure growth of plant there are a
measuring tools specially is called auxanometer.
Growth of Plant
Plant Growth
• Growth is the process by which a plant increases in
the number and size of leaves and stems. The result of
plant growth is forage production and the amount
harvested by animal or machine is forage yield.
• The growth of both plants and animals requires
energy. Animals get their energy by digesting the
plants they eat. Plants get their energy from the sun
through photosynthesis
Development
 Development is one of change of organism towards
adulthood and usually cannot be measured by
measuring tools or have the qualitative value.
 Example : Maturation of ovum cell and sperm, and
hormones.
Plant Development
• Plant development is the process of a plant changing
from one growth stage to another. This could be the
development of tillers on a grass plant or flower buds
on a legume plant.
• Plant development is the major factor affecting
forage quality. As plants change from vegetative to
reproductive stages, forage quality decreases. When in
the reproductive stage, both grasses and legumes
produce
Growth and Development
The Definition
Metamorphosis is the change
of shape from a certain phase
until adult phase (imago).
There are two metamorphosis:
 1. Complete metamorphosis
 2. Incomplite metamorphosis
Complete metamorphosis
• Complete metamorphosis
Have four stages. Egg-larva-pupa-adult
Hatchling does not resemble adult closely, they usually
have different food, habit and habitat than the adults.
(Example: Frog and Butterfly)
Complete metamorphosis on Frog
Complete metamorphosis on
Butterfly
incomplete metamorphosis
• Incomplete metamorphosis
Have three stages. Egg-nymph-adult
Hatchling closely resemble adult. The main difference
usually they are wingless for the species whose adults
have wings. Often they share the same food, habit and
habitat of the adults.
(Example: Grasshopper)
Incomplete metamorphosis
