Growth Characteristics in Living Organisms

The video tutorial discusses the concept of growth in living organisms, defining it as an increase in mass and cell number. It contrasts this with growth in non-living things, which is merely an external accumulation of mass. The tutorial highlights the internal nature of growth in living organisms and compares the continuous growth of plants with the limited growth period in animals.

What is the primary definition of growth in living organisms?

• Decrease in cell number

• Increase in mass and cell number

• External accumulation of substances

• Decrease in mass

How do non-living things exhibit growth?

• Through metabolic processes

• Through internal cell division

• By increasing their lifespan

• By external accumulation of substances

In what way is growth in non-living things similar to living organisms?

• Both involve internal cell division

• Both involve increase in lifespan

• Both involve external accumulation

• Both involve metabolic processes

What distinguishes growth in living organisms from non-living things?

• Living organisms grow only externally

• Non-living things grow internally

• Non-living things have metabolic growth

• Living organisms have both internal and external growth

What is the main characteristic of growth in living organisms?

• External accumulation

• Internal and external development

• Only internal development

• No development

Which of the following is not a characteristic of growth in living organisms?

• Increase in mass

• Increase in cell number

• Internal development

• External accumulation only

Which statement is true about plant growth?

• Plants have a limited growth period

• Plants grow only during the day

• Plants grow throughout their entire lifespan

• Plants stop growing after flowering

What is a unique feature of plant growth?

• Plants stop growing after a certain age

• Plants grow continuously throughout life

• Plants grow only in the summer

• Plants have a defined growth period

What is a key difference between plant and animal growth?

• Animals grow throughout their lifespan

• Plants have a specific growth period

• Animals have a limited growth period

• Plants stop growing after a certain age

How does the growth period of animals differ from that of plants?

• Animals stop growing after flowering

• Animals grow only during the night

• Animals have a defined growth period

• Animals grow continuously like plants
