Life Science or Biology class.
We began the year with the basic unit of life, the cell. In other words, the cell is considered the smallest thing that is alive. In order for something to be alive, it needs to have these 6 characteristics.
All living things are made of cells
Respond to stimuli
The organelles of a cell work together to keep the cell alive. The major organelles of the cell covered are the nucleus, Endoplasmic reticulum, mitochondria, Golgi body, cell membrane, lysosomes, and ribosomes.
Life also has levels of organization cells make tissues which make organs which make organ systems make organisms.
The cell divides during cell division which includes mitosis
Cell division begins during interphase when the cell makes copies of organelles and DNA
Mitosis begins with prophase when chromosomes first appear
During the year in Life Science or Biology class, we discuss how the body systems work together to keep the body alive. These systems include,
Genetics is the study of how traits are passed from one generation to the next.
the following topics
Genes and chromosomes and traits
Working out Punnett squares
Evolution helps explain the variety of life.
We also covered an ecology unit and studied, symbiotic relationships, food webs, and the major land biomes.
