Life processes – 5
Q1. How can we say that organisms are alive?
- They move themselves
- They breathe
Q2. What is growth dependent and growth independent
movement?
Growth dependent:
- Happens because of growth
- Example: seed germination and transformation of a baby plant to
a tree
Growth independent:
- Happens without growth
- Example: touch-me-not plant shrinks and folds when touched
Q3. What is invisible movement and visible movement?
Invisible movement:
- Cannot be seen with naked eyes
- They are molecular movements
, Visible movement:
- Can be seen with naked eyes
Q4. What is a virus?
- A virus is a tiny organism
- Shows no signs of life outside a living cell
- Once it enters a living cell, it becomes active and spreads rapidly
Q5. What is homeostasis?
- Organised ordered nature
Q6. Why are repair and maintenance required for a living
organism?
- Environmental effects break the organised order
- Repair and maintenance are required for recovery
Q7. What are life processes?
- The maintenance functions of living organisms must go on even
when they are not doing anything particular
- The processes which together perform these maintenance jobs
are called life processes
Q8. Explain four types of life processes.
