WHAT IS PLANT?
Plant is a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and
mosses, typically growing in a permanent site.
PLANT PARTS AND FUNCTIONS
The root is the part of the plant that takes in water and minerals for the plant.
Roots have root hairs that increase the surface area for more water absorption.
The stem has vessels that transport sap and water throughout the plant.
Sap is a nutrient-rich fluid that contains a lot of sugar.
Two Functions of the Leaf
Photosynthesis is the process when leaf cells containing chlorophyll take in carbon
dioxide and water and using sunlight, make sugar and oxygen.
Transpiration is the loss of water from the leaf. This helps to draw water up through the
plant from the roots.
The flower is the organ of reproduction in flowering plants.
The male part of the flower is the stamen (composed of the anther where pollen is
made and the thin filament).
The female part of the flower is the pistil (composed of the stigma, the thin style and
Pollination occurs when pollen is transferred by insects or wind from the anther to the
stigma. Chemicals called enzymes 'drill' a channel down through the style to the ovary
where the egg is.
Fertilisation occurs when the pollen joins with the egg. After this, a seed forms inside a
Germination is the process when a seed grows into a seedling.
USES OF PLANTS
Food -> Starches and sugars, the foods that plants make and store for their own growth, are also
the fundamental nutrients that humans and other organisms need in order to live.
Clothing -> Much human clothing is made from material that comes directly from plants. Cotton
is the principal plant used for clothing manufacture. Artificial textile fibers, such as rayon, are
manufactured chiefly from cellulose, which is found mainly in the cell walls of plants. Linen is
obtained from the flax plant.
Paper -> Plant fibers are placed in water and reduced to a pulp. The water is sieved off, and the
pulp is pressed
Shelter -> in many parts of the world is made from wood. Plant materials appear in a number of
places in human dwellings.
Medicine -> people have found that certain plants could be used to relieve their aches and pains.
Most medicine men and physicians in ancient cultures were experts on plants. In fact, the study
of botany in Europe and America had its beginnings in medicine, when doctors searched for
herbs to cure disease.
PLANT PROPAGATION is the process of creating new plants from a variety of sources:
seeds, cuttings, bulbs and other plant parts. Plant propagation can also refer to the artificial or
natural dispersal of plants.
Sexual propagation (seed)
Seeds and spores can be used for reproduction (through e.g. sowing). Seeds are typically
produced from sexual reproduction within a species, because genetic recombination has
occurred. A plant grown from seeds may have different characteristics from its parents. Some
species produce seeds that require special conditions to germinate, such as cold treatment. The
seeds of many Australian plants and plants from southern Africa and the American west require
smoke or fire to germinate. Some plant species, including many trees do not produce seeds until
they reach maturity, which may take many years. Seeds can be difficult to acquire and some
plants do not produce seed at all.
Plants have a number of mechanisms for asexual or vegetative reproduction. Some of these have
been taken advantage of by horticulturists and gardeners to multiply or clone plants rapidly.
People also use methods that plants do not use, such as tissue culture and grafting. Plants are
produced using material from a single parent and as such there is no exchange of genetic
material, therefore vegetative propagation methods almost always produce plants that are
identical to the parent. Vegetative reproduction uses plants parts such as roots, stems and leaves.
In some plants seeds can be produced without fertilization and the seeds contain only the genetic
material of the parent plant. Therefore, propagation via asexual seeds or apomixes is asexual
reproduction but not vegetative propagation.
