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 develompmentExternal factors:• Water and minerals• Nutrition• Air• Weather• Temperate• LightInternal Factors:• Gens• Hormon (endocrine)

Differentiate of Growth and DevelopmentGrowth

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 GrowthPlant stem that has length 2 cm become 5 cmBaby which weight 5 kg turn on into 6,5 kgWhen 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

DevelopmentDevelopment 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 DefinitionMetamorphosis is the change of shape from a certain phase until adult phase (imago).

There are two metamorphosis:1. Complete metamorphosis2. Incomplite metamorphosis

Complete metamorphosis• Complete metamorphosis

Have four stages. Egg-larva-pupa-adultHatchling 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-adultHatchling 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 on Grasshopper
