**Growth and Reproduction in Plants and Animals**
**Plants**
- Growth: Plants exhibit two types of growth - primary growth (lengthening of roots and shoots) and secondary growth (increase in thickness due to lateral meristems).
- Reproduction: Plants reproduce sexually through the formation of flowers containing male and female reproductive organs. They can also reproduce asexually through methods like vegetative propagation.
**Animals**
- Growth: Animals grow by increasing the number and size of their cells. Different species have different growth patterns, such as indeterminate growth in some fish and reptiles.
- Reproduction: Animals reproduce sexually through the fusion of gametes (sperm and egg). Mammals have internal fertilization, while most fish and amphibians have external fertilization.
In conclusion, growth and reproduction are essential processes in the life cycles of both plants and animals. Understanding these processes is crucial for the study of biology and the conservation of species.
