the cytoskeleton
Millions of years of evolution. thats the wrong answer
Animal cells are given their shape and sturdiness by the cytoskeleton, which is a network of protein filaments that provide structural support and help maintain cell shape. The cytoskeleton also plays a role in cell movement, division, and intracellular transport.
The shape and sturdiness of animal cells are primarily determined by the cytoskeleton, a network of protein filaments and tubules that provide structural support and maintain the cell's shape. Additionally, the cell membrane, which is flexible yet robust, plays a role in maintaining the integrity of the cell. Unlike plant cells, animal cells do not have a rigid cell wall, so their shape is more variable and relies heavily on the cytoskeleton for support.
The cell wall of plant cells is the part which gives the cell sturdiness and rigidity.
Plant cells are surrounded by a stiff cell wall made of cellulose, which makes the cells very rigid. It is this strong structure that gives plants their sturdiness.
One example of a structure that protects and gives shape is the skeleton in humans and other vertebrate animals. The skeleton provides support for the body, protects internal organs, and allows for movement. It is composed of bones that are connected by ligaments and tendons.
The cell wall of plant cells is the part which gives the cell sturdiness and rigidity.
Becuse plant cells need structure and the cell wall gives it that and it also gives it a defined shape and animals have spines instead so it is not needed/used.
In the real world no animal can shape shift.
tringular shape
The skeletal system gives the body shape and strength.
