Study Notes
Reproduction
- Organisms reproduce to create new individuals, ensuring species continuity.
- Asexual reproduction involves a single parent producing offspring that are genetically identical to each other and the parent.
- Sexual reproduction requires two parent organisms, leading to the production of gametes (sex cells) that fuse during fertilization.
- Offspring from sexual reproduction exhibit genetic variation, making them unique compared to each other and their parents.
Sensitivity
- Living organisms can detect changes in their environment, known as stimuli (plural: stimuli).
- Sensitivity refers to the ability to sense and respond to these stimuli effectively.
- Plants demonstrate sensitivity by orienting their leaves towards sunlight to maximize photosynthesis.
- Some flowering plants exhibit behavior by opening in the morning to absorb sunlight and closing at night for protection.
- Animals possess sensory cells and specialized sense organs to detect environmental stimuli such as light, sound, touch, pressure, and airborne or food-related chemicals.
