Growth refers to an increase in size or mass, while development involves changes in complexity and function. Growth is quantitative, whereas development is qualitative, encompassing the maturation of structures and abilities.
Genetic material, such as DNA, provides the instructions for developing and functioning of organisms. During reproduction, genetic material is passed to offspring, ensuring that traits and characteristics are inherited and maintained across generations.
Reproduction can be sexual or asexual. Sexual reproduction involves the fusion of gametes from two parents, while asexual reproduction involves a single organism producing offspring without gamete fusion, such as through budding or fission.
Reproduction ensures the continuation of a species by producing new individuals. This process helps pass on genetic information to offspring, allowing species to adapt and survive across generations despite environmental changes.
Living creatures use feedback mechanisms, such as temperature regulation and hormonal adjustments, to maintain homeostasis. These mechanisms help regulate internal conditions and respond to external changes to keep the internal environment stable.
Living creatures grow by increasing in size and complexity. This growth involves cellular multiplication and expansion, development of tissues and organs and overall maturation, driven by genetic instructions and environmental factors.
For a creature to respond to stimuli means it can detect changes in its environment and react accordingly. This response can involve movement, behavioral changes or physiological adjustments to maintain homeostasis.
Seeds with excess water may not germinate due to waterlogging, which reduces oxygen availability, leading to poor respiration and possibly rotting. Class 6 Science NCERT Chapter 10 Chapter 10 Living Creatures: Exploring their Characteristics
Living creatures reproduce through various methods, including sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female gametes, while asexual reproduction involves producing offspring without gamete fusion, like budding or binary fission.
