A living organism has the power of growths Growth begins as the intake of food is greater/
than the immediate demand in animal and plant body. The body of the living organism may
increase in size, in weight and in complexity, when growth takes place..
6. Excretion
bxcretion means eLaminat-zon or wable
materials in the body of a living organism. This ie the natural result of respiration. The waste products are got rid of as by-products of metabolism.
In all living organisms the two principal waste products are water and carbon dioxide.
In animals there is a third, called urea, collected in special excretory organs while plants have no special excretory organs, but they give off carbon dioxide and water vapour into air through small openings, stomata. Reproduction
Living organism has the power of reproduction. This is the most striking and important property by which it is distinguished from non-living organism. This is the way to give rise to new generations so as to prolong the offsprings of species and kinds in animals and plants. There is of great variety of processes of reproduction. Mostly there are simple or binary fission, reproduction by budding which collectively are termed asexual reproduction and sexual reproductio which is common among higher animals and higher plants,
8. Protoplasm

To possess the property of irritability means to have active response to stimulus set up in the organism. This resulte in movement, usually, in animals, though this is not necessarily in che case of plants.
Movement or locomotion.
Similarities:
Both amoeba and spirogyra are different in mode of nutrition but have the same process of absorption and assimilation, Amoeba and spirogyra both have asexual reproduction and the latter even has sexual reproduction. too. The ampeba, even up to now, has no report to carry out sexual reproduction.
Differences:\
Amoeba, by moving its pseudopodia, encloses microscopic organisms or decayed remains of larger plants by the formation of food vacuoles, The food in' the food vacuoles is slowly digested by secretions poured out by its surrounding cytoplasm. The food is then] dissolved into simple diffusible form.

IBRARIES
A living organism, both plants and animals,
can move. However, a living animal moves either
of its own accord or in response to some external
influencé, Plants are not able to move more
freely in environment than animals but may motivate according to tropisms such as hydrotropism and phototropism.
KON
* Respiration:
Living organisms require energy for all activities and obtain energy from respiration.. Respiration by biological sense means process by which energy to made available, Both plants and animals respira sccording to environmental conditions.
Nutrition

A
Fig 2
Living organism needs matters from external environment as means of energy, necessary for building up the body. In addition, every living organism must feed in order to live.
The method of nutrition for animal 18 holozoic and that for plant is holophytic. Holozoic nutrition is to digest and absorb solid organic food in solution. Holophytic nutrition means to take food from carbon dioxide and water, under sunlight and in the presence of chlorophyll by the mechanism of photosynthesis,
However, the feeding movements of animals
can usually be seen. The feeding plants is an invisible process., Growth
