A cell is the smallest part of a living organism that contains the identity within a strand of DNA. The cells of your body can grow into specialized functions such as heart or skin. Some microscopic organisms are 1 cell creatures or simple multi-cell organisms. That is what is mean by "All living organism are composed of cells."
Yes, all livings beings are composed of either one or more cells; so much that having cells in one property of life.The closest biological particles to living organisms, that lack cell structure, are viruses, but they are not considered to be alive because they don't have a metabolism of their own.
For things to be considered living they must meet some requirements. These are being able to grow, reproduce, adapt to their environment, and be composed of cells.
No, not all living things have cells. While all living things are made up of cells, some organisms like viruses are considered living but do not have cells. Instead, viruses are composed of genetic material (DNA or RNA) enclosed in a protein coat.
some cells are living some are not
Really, it depends on the thing. A plant can be composed of hundreds of millions, while human being are composed of trillions! It would be nigh impossible to count every single cell in even one living thing (since non-living things are not made of cells) because cells are constantly dieing and multiplying.
Yes, living systems are typically composed of two or more cells. The majority of organisms, including plants, animals, and humans, are multicellular, meaning they are made up of multiple cells working together to form tissues, organs, and complex biological systems. However, some organisms, like bacteria, are unicellular and consist of just one cell.
There are as many types of living cells as there are organisms on the planet. Almost all living cells, however, feature some common components. Among these essential components are a membrane, membrane proteins, proteins, DNA and transport systems.
Most minerals are composed of two or more elements. Some common minerals, such as quartz, are composed of just two elements (silicon and oxygen), while others may contain multiple elements in their composition.
Not all living cells are considered organisms because organisms are typically composed of multiple cells working together in a coordinated manner to carry out life functions. Some cells, like red blood cells, lack organelles and cannot function independently as a whole organism.
Matter and weight. Life needs something that makes it want to live, so it will have to have some form of a control or nervous system or brain. Also because "life" is alive it needs sustenance (food of some kind). It will also have some form of reproduction.
This thin layer is called the "Buffy Coat" it is composed of some white blood cells and platelets.
