Characteristics of Living things Video Lecture - Class 5

0:0:0: introduction
0:0:2: look Rahul this robot is walking yes
0:0:7: this robot can do many other words Rahul
0:0:11: do you know the difference between
0:0:12: living and nonliving things Radhika I
0:0:16: know only one difference that living
0:0:19: things move but if it is true then why
0:0:22: this robot is not considered as living
0:0:26: children in this lesson we will learn
0:0:28: about characteristics of living things
0:0:31: objectives
0:0:34: at the end of this lesson you'll be able
0:0:37: to define life identify
0:0:41: characteristics of living things learn
0:0:44: that living things have cells identify
0:0:48: that living things grow and develop know
0:0:51: about the use of energy by living things
0:0:54: identify that living things sends and
0:0:57: respond to change discuss that living
0:1:1: things reproduce life life is unique
0:1:5: complex cellular organization of
0:1:8: molecules expressing it through chemical
0:1:10: reactions which lead to growth
0:1:12: development responsiveness adaptation
0:1:16: and reproduction characteristics of
0:1:19: living things things which depict growth
0:1:22: reproduction ability to sense
0:1:25: environment and mount of suitable
0:1:27: response are called
0:1:29: living things plants and animals both
0:1:32: are living there for biology deals with
0:1:35: the study of both plants botany and
0:1:37: animals the zoology all living organisms
0:1:41: share following basic characteristics
0:1:43: since and respond to change and growth
0:1:47: and development give off a waste
0:1:51: reproduce living things have cells each
0:1:56: living being has a distinct
0:1:57: individuality it cannot be broken into
0:2:0: two or more independent parts the body
0:2:4: of a living being is made of one or more
0:2:6: cells cells are considered to be
0:2:9: structural and functional unit of life
0:2:12: the cells are made of protoplasm or
0:2:15: living matter all the body functions and
0:2:18: properties of life are due to protoplasm
0:2:21: some living organisms like amoeba
0:2:24: Paramecium are made up of one cell only
0:2:27: they are called unicellular organisms
0:2:30: made up of many cells are called
0:2:33: multicellular living things grow and
0:2:35: develop all organisms grow and develop
0:2:40: growth results in an increase in size
0:2:43: weight and synthesis of new protoplasm
0:2:48: in animals growth is limited to a
0:2:50: certain age while plants grow all the
0:2:52: life the use of energy by living things
0:2:56: living being constantly requires energy
0:2:59: not only to perform various activities
0:3:1: of the body but also to overcome entropy
0:3:3: the degree of disorder in a system or
0:3:6: tendency to randomness and the source of
0:3:9: energy is food it is required by every
0:3:13: cell of the body food is prepared by
0:3:16: plants by the process of photosynthesis
0:3:19: plants require sunlight carbon dioxide
0:3:23: water and chlorophyll for the process of
0:3:26: photosynthesis the living things respire
0:3:30: living things require oxygen to get
0:3:32: energy from the food they get required
0:3:36: oxygen by the process of respiration
0:3:38: during respiration oxygen is breathed in
0:3:42: and through the blood it reaches each
0:3:44: and every cell of the body human beings
0:3:48: have lungs for respiration fishes have
0:3:51: gills and cockroaches have spirals
0:3:54: living things sense and respond to
0:3:57: change consciousness is awareness of the
0:4:1: surroundings and responding to external
0:4:3: stimuli the ability of an organism or
0:4:6: organ to respond to external stimuli is
0:4:9: called sensitivity living things
0:4:11: reproduce young ones grow and become
0:4:15: mature they developed the Faculty to
0:4:18: produce young ones of their own time
0:4:20: life comes from pre-existing life
0:4:25: Samri
0:4:27: let us summarize what we have learned in
0:4:30: the world there are two types of
0:4:32: structures living and nonliving living
0:4:36: beings are complex entities all living
0:4:40: organisms share some basic
0:4:41: characteristics cellular structure use
0:4:45: energy grow and develop sense and
0:4:48: respond to change move give off waste
0:4:52: and reproduce the smallest unit of life
0:4:56: is cell changes in structure and
0:5:0: function of every living being with age
0:5:2: are called development a living organism
0:5:6: can be unexceptional e differentiated
0:5:9: from a nonliving thing on the basis of
0:5:11: its ability for reproduction
