what is the structure of unicellular organisms
made up with cytoplasm and organelles enclosed by plasma membrane
write different types of cells in human body
skin cells, gamete cells, nerve cells, bone cells, white blood cells, red blood cells, muscle cells
what is nutrition
the process by which the energy and the materials are obtained for the maintenance of life is known as nutrition
what are the two types of autotrophism
photoautotrophics and chemoautotrophics
define photoautotrophic
when an organism is using light energy as the nutritional source photoautotrophic
what is cellular respiration
the process by which the stored food is transformed into energy inside the cells is known as cellular respiration
what is stimulus
a change which is strong enough to bring about a response is known as stimulus
what is known as response
the reaction according to the changes in the environment are known as responses
what is irritability
the ability to respond to stimuli receives from internal or an external environment is known irritability
what is co-ordination
the communication between different organs during respond to the stimulus is known as co-ordination
what is excretion
Removal of the waste products from the body that are produced during metabolism is known as excretion.
name different ways of excretion of living being
sweat,exhale gas,urine
write main excretory materials
urea, salts, CO2
and water
what is reproduction
Production of a new generation by a unicellular or a multicellular organism
for the continuation of their species is known as reproduction.
