Because we are made of millions of cells while an amoeba is just one cell. Large organisms made of many cells need solid supports to stand up.
No, an amoeba doesn't need fertilization to reproduce. An amoeba reproduces asexually.
Land animals need a skeletal system to provide support and protection for their bodies since their cells do not have a cell wall. The skeletal system also allows for movement by providing attachment points for muscles.
fooddddddddddddd!
The scientific name of the amoeba is... Amoeba. Amoebas belong to the genus Amoeba. You have distinct species like Amoeba proteus and Amoeba dubia.
sun , water, air
It would be inpossible to move. We would be like a large bouncy ball.
The skeletal system meet the cells need by .....
We are eukaryote which means are cells are more advanced than there's. And since we have more cells than a amoeba. Our cells carry oxygen to the brain and other organs in the body. A amoeba dose not have a brain. So it doesn't need a circulatory system.
An amoeba does not need a blood system because its body has other organelles that it uses to survive. Plus a blood system is made up of many different cells and an amoeba consists of only one cell, that is why it is called a single celled organism.
Your skeletal system is one of the most important systems in your body. It is the foundation for your body and if you didn't have it, your body would be a pile of flesh and guts.
heart brains lungs
Amoeba can die if they lack oxygen. They need it.
no they are to small to have a respiratory system or organ so they breath through there cell membrane
If we didn't have a skeletal system we would be a blob on the ground. If we didn't have bones well basically the same thing but also we wouldn't be able to produce blood or marrow.<----- (important) We also need tendons and ligaments so our muscles stay attached to our bones (another reason why we need bones) and allow smoother movement.
All organ systems work together. First of all you need energy, digestive system does that. Then the circulatory system takes the food and takes it to the body. And for cellular respiration you need oxygen, so respiratory does that. And nervous is for telling and thinking what to do. And the main ones are skeletal and muscular systems. Muscular move bones which are from the skeletal system.
Humans have a complex circulatory system to efficiently transport oxygen, nutrients, hormones, and waste products to and from cells throughout the body. Amoebas, being single-celled organisms, can rely on simple diffusion to exchange gases and nutrients with their environment due to their small size and surface area.
It's because humans have sexually reproduction that why they can't reproduce by asexually means (like amoeba which fusses itself) I think that is the answer.
