Nature Of Living Organisms

Ability to change postion

Chemical Breakdown of food to release energy

Ability to detect and respond to change in environment

Permenat increase in size

Produce offspring

Get rid of metabollic wastes

Intake of food for energy growth and development

In prokaryotic nucleus absent Unicellular Have circular chromosome of dna and has plasmid Eukaryotic contain nucleus Unicellular or multicellular More than one chromosome

Both multicellular organisms

Plant contain chloroplasts so can carry out photosynthesis but animal don’t have Plants contain celluose cell wall but animal don’t have cell walls Plant store carbohydrates as starch or sucrose but animal store carbohydrates as glycogen

Organism cannot carry out photosynthesis Some are single cell as yeast Cell wall made of chitin Body organized into mycelium made from thread like structure call hyphae Store carbohydrates as glycogen

Single celled organism Some have features like animal cell like amoeba Protists like chlorea have chloroplasts like plant cell

Plasmodium, malaria

Cell wall made of murien No nucleus but contain circular chromosome of dna Have cell membrane cytoplasm plasmids,flaggelum, capsule Some bacteria can carry out photosynthesis

Spherical bacterium that act as patgegon cause pneumonia

Lactobacillus bulgaricus rod shape bacterum use in production of yoghurt from milk

Organism causes disease Including virus, bacteria,fungi, protoctists

Non living organisms Don’t respire grow feed or excrete Smaller than bacteria Reproduce only inside their host cell No cellular structure but had protein coat and contain one type of nuclic acid either dna or RNA Virus are parastic and infect any type of organism

Tobacco mosaic cause discoloring leaves of tobacco plant prevent formation of chloroplasts Influenza virus cause flu Hiv virus cause aids

Feed by extracellular secretion of digestive enzymes onto food mayerial and absorb of organic products

Chemical reaction takes place inside cell

Change in external or internal environment of organism such as light,heat,pain

Actual mass of organism after remove its water content
