BASED ON ORGANOLEPTIC OF STEM

1. Herbaceus (Wet Stem) stems are soft and watery, for example in spinach (Amaranthus spinosa L), Purslane (Portulaca oleracea L).

2. Lignosus ( Woody Stem)Stems are hard and strong. because it consists mostly of wood found on the trees (arbores) and scrub-shrub (frutices) in general.

3. Grass stems (calmus)which is not that hard rod, sections have real and often hollow, for example in rice (Oryza sativa) and grass (Graminae) in general.

4. Mendong rod (Calamus), such as switch grass, but has sections that are longer, for example in rushes (Fimbristylis globusa Kunth).

BASED ON LONG LIFE PLANTS

Annual, or less if the plant life reaches a maximum of one year. Such plants, generally flowering only once, then die after the fruit is ripe. example: corn, soybeans, tomatoes, peanuts.

Biennial (2-year plants), which completes the circle of plants ranged from more than one year to two years. generally only bloom one time during the vegetative period has completed more than one year. Eg type of shrub sidaguri (Sida rhombifolia; Malvaceae)

Parennial, the plants which life in the long times. Example : Metroxylon sagu, Corypha umbraculifera

Form of Plants LifeAccording to Raunkiaer (1934) , the range of adaptation of

plants relates to the mode of shoot withdrawal in theunfavorable season.

One of the first to provide a comprehensive system of plantlife form classification based on their adaptations forsurviving the unfavorable season (winter cold or summerdrought). Adaptations for survival linked to the protectionafforded to the sensitive apical meristems or classification ofplant life in relation to the HEIGHT of PERENNATING tissue(embryonic or meristemic tissues that remain inactive overwinter or prolonged dry periods) above ground.

It can distinguish to , phanerophytes, chamaephytes,hemicryptophytes, cryptophytes and therophytes.

Therophytes

Phanerophytes (phanero = visible)Trees and shrubs greater than 25 cm in height that have their leaf-producing buds elevated above ground on stems.

Hemicryptophyt

Cryptophytes

Therophytes

Chamaephytes (chamae = dwarf)Perennial shoots or buds are on the SURFACE of the ground to about 25 cm ABOVE the surface.

1. Subfructicosa chamaephytes, the buds are protected by the ingredients.

2. Passive chamaephytes, stem extends above the ground.

3. Active chamaephytes, buds above ground.

4. Cushion chamaephytes, transition Chamaephytes and Hemicryptophytes.

Cryptophytes

Therophytes

Cryptophytes (crypto = hidden)grasses which have above-ground tissues that die back in winter or during prolonged dry periods and survive unfavorable periods as buds buried in the ground on a bulb or rhizome.

Cryptophytes

Therophytes

Therophytes (thero = summer)Annuals that survive unfavorable periods as seeds and

complete their life cycle from seed to seed in one season.


HOME MATERIAL

In nature based on where and how to plant life can be

observed in the presences

Epiphytes (Epiphyte) ie plants that ride on other

plant parts. For example orchid and Pterydophyta.

Epifil, stature aboard on the leaves of other plants

Liana is a climbing plant to another plant (can be

with the help of pembelit leaves, roots sticker, thorn

hooks, pembelit branches, leaves pembelit, etc.)

which is essentially to compete gets sunlight.

Parasitic plant that is riding and sucking food from

their host plants such as mistletoe (Dendroptheo

pentandra; Loranthaceae) .



HOME MATERIAL

Molt is the adaptability of plants at a time when water

shortages/dry season by the way has waived its leaves.

Molt aims to minimize the occurrence of evaporation

of water. Leaf will back blossomed while entering the

rainy season/when available water. Examples of plants

is the Teak, mahogany, randu and kedondong.

Plants live in the watery environment

A broad leaf will accelerate the process of evaporation

due to the shape of the cross-section width multiply

the area exposed to the sun light. Examples of plants

that have leaves are wide and thin is the Lotus,

banana and taro.



HOME MATERIAL

Plant eaters of insects aims to fullfill needs nutrient

substances/nitrogen which is not retrieved from the

ground. An example of this is the Nepenthes plants

and venus.

Plants are sensitive to stimulation, it will close the

leaves when in touch.
