Why do animal grow until a particular size whereas plants all their lives?

Animals grow until they reach a particular size because their growth is determined by their genes. Genes control the production of proteins, which are the building blocks of cells. The rate of protein production determines how fast an animal grows. When an animal reaches its adult size, its genes stop producing proteins, and the animal stops growing.

Plants, on the other hand, do not have a fixed growth pattern. They can continue to grow throughout their lives, as long as they have access to water, nutrients, and sunlight. This is because plants produce new cells throughout their lives, a process called meristematic growth.

The difference in growth patterns between animals and plants is due to the different ways that their cells are organized. Animal cells are organized into tissues and organs, while plant cells are organized into tissues, organs, and systems. This difference in organization allows plants to continue to grow throughout their lives, while animals reach a fixed size.

Here are some additional details about animal and plant growth:

Animal growth:

* Animal growth is controlled by hormones, such as growth hormone and insulin.

* Animals grow in spurts, with periods of rapid growth followed by periods of slower growth.

* The rate of animal growth is influenced by factors such as nutrition, environment, and genetics.

Plant growth:

* Plant growth is controlled by a variety of factors, including water, nutrients, sunlight, and temperature.

* Plants grow continuously throughout their lives, although the rate of growth may vary depending on the season.

* The growth of plants is influenced by factors such as genetics, environment, and climate.
