1. Differentiate between the following :
a unicellular and multicellular
b.autotrophs and heterotrophs
2. Give an example of a non-living thing that exhibits any two characteristics of a living thing 3. List two ways by which animals reproduce 4. Write the importance of seeds in plants.
5. How is the process of growth different from that of development?
Answers
1.a.
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism.
multicellular organisms use many different cells to function. ... For example, a paramecium is a slipper-shaped.
unicellular organism found in pond water.
b.autotrophs - it is the mode of nutrition in which organisms make their own food through the process of photosynthesis.
heterotrophs -the organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”
2.The bus is an example of a non-living thing that shows two characteristics of living things. Like living things, it can move from one place to another and it also requires energy to do work.
3.Animals can reproduce in two different ways which are Asexual Reproduction and Sexual Reproduction.
4.Seeds are of immense biological and economic importance. They contain high protein, starch and oil reserves that help in the early stages of growth and development in a plant. These reserves are what make many cereals and legumes major food sources for a large proportion of the world's inhabitants.
5.Thus, growth refers to an increase in physical size of whole or any of its part and can be measured. Development refers to the qualitative changes in the organism as whole. Development is a continuous process through which physical, emotional and intellectual changes occur.
