Such organisms are said to be multicellular. Human beings fall under that category.
Sperm and egg cells, or any cell that only contains one set of chromosomes, are called haploid cells.
haploid cells
The nucleus contains the genetic material, including DNA, which carries the instructions for making proteins and controlling cellular activities. These instructions are important for the functioning and development of the organism, making the nucleus the control center of the cell and often referred to as having the "instructions for life."
first of all these are the correct spellings: "Specialization, multicellular, and organism" in a nutshell, it is why we have skin cells, nerve cells, muscle cells, etc. It is the specialization of the cells due to differences in gene expression of said cells.
They are living, but they are not organisms. Cells are the "building blocks" of tissues, which group together into organs, which group together into organ systems. Those organ systems comprise an organism. The individuals cells are not organisms themselves.
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."
A cell that contains both sets of homologous chromosomes is said to be diploid. In diploid cells, one set of chromosomes is inherited from each parent, allowing for genetic diversity. This is typically the case in somatic cells of multicellular organisms, while gametes (sperm and egg cells) are haploid, containing only one set of chromosomes.
Cells are actually the elemental constituents of body who unite together to form tissues and these later unite to form an organ, then organism. So it can be said that cells are building blocks of human body. The cells can be haploids or diploids and they form chromosomes. the Chromosomes can be either sex linked chromosomes or non sex linked chromosomes. These cells undergo cell division process either through "MITOSIS" or "MEIOSIS" to form chromosomes. Depending upon there linkage as sex or non-sex they help in determining the genotype and phenotype of the organism. Thus we see that it's the cells that determine the genotype or the genetic constituent of the organism and also the phenotype or the physical characteristics of the organism.
Rudolf Virchow said that all cells come from existing cells.
Haploid. A haploid cell contains one set of chromosomes (n), which is half the number of chromosomes found in a diploid cell. Haploid cells are typically found in reproductive cells like eggs and sperm.
A forest is considered as a community, for many living organism take shelter and feed there.
