Objectives:
a.identify
the structure and Characteristics of plants;
b.enumerate
each plants that belong to the adaptation and their survival and;
c.differentiate
each plants.
Plants
have structures and characteristics that protect themselves from humans and
other animals. Here are some examples of these plants:
ROSE PLANT
The
roses are shrubs or scandent
shrubs, cultivated or wild. Theirs stems are often armed with
prickles, their leaves are composed and theirs flowers are more or less fragrant and multicolor.
•They
belong to the genus Rosa, within the family Rosaceae.
They are native to the temperate regions of the northern hemisphere.
•The
botanical classification of indigenous roses includes 150 species in the genus
Rosa. Over the course of time, however, natural and spontaneous crosses have
been produced and have created many hybrids. In addition, man has intervened
since the 19th century : species and natural hybrids have been used to
obtain yet more new varieties, called cultivars (from
cultivated varieties).
EUPHORBIA
Euphorbia tirucalli has unmistakable,
brush-like branch masses
that are a noticeable feature
of the plant. It
also occurs over the widest
distribution of all local
euphorbias and
is also a
very variable plant ranging from many-branched shrubs to large trees, depending
on the particular habitat.
•they
belong to the Family of Euphorbiaceae
• the
Common names of
this plant are pencil
plant, rubber-hedge euphorbia (Eng.); kraalmelkbos (Afr.)
•The
plants are drought resistant and very resilient, which is why it has become
popular in cultivation. It uses its green stems to photosynthesize and is
therefore able to minimize surface exposure and water loss.
Euphorbia
tirucalli grows
moderately fast and thrives in moderate to warm climates. It does not seem to
cope with extreme cold. Plants can easily be cultivated by means of seeds,
cuttings or truncheons. A coarse sandy medium is ideal for sowing the seeds
MAKAHIYA PLANT
A common sight in Philippine grasslands, the makahiya
plant (Mimosa pudica) is
famous for its tendency to curl up its leaves at the slightest touch, as if it were extremely embarrassed about physical contact, hence its name:
"makahiya"
is derived from the Filipino word for "shame" or "shyness"
("hiya").
•They
belong to the Family(a) Fabaceae
– peas; legumes (b) Poaceae
– grasses; graminées
•Their
common name are (a) Makahiya
(Filipino); Touch-me-not; Shameplant
(English) (b) Kogon
(Filipino); Cogon grass (English)
•Lightly
touching the leaves causes the plant to withdraw them almost instantly, and the
phenomenon is admittedly both remarkable and amusing to anyone who's tried it.
vThese
plants have thorns to warm humans and other animals to keep away from them.
vThese
THORNS is a modified branch in the form of a sharp, woody spine. When it is
touched carelessly, it causes sharp pain, irritation or discomfort.
vSome
grasses like the bamboo and talahib have
fine hairs on their leaves. These fine hairs when touched can cause irritation
and itchiness of the skin.
vSome
plants have sharp leaf blades capable of cutting the skin. An example of these
plant is the pine apple.
Pineapple, Ananas
comosus,
belongs to the Bromeliaceae family,
from which
one of its most important
health- promoting compounds,
the enzyme
bromelain, was named.
vSome
plants have special features that help them to repel predators. Other plants
can survive and even thrive in hostile environments, such as cold and rocky
mountains. In areas of little rainfall, plants known as XEROPHYTES have
developed special methods for collecting and storing water. Another group of
amazing plant survivors are known as HALOPHYTES.
They can endure extremely salty regions, such as salt marshes, salt pans, and
sand dunes
