Cells Cell Theory- Cells are the smallest units of life All organisms are made of one or more cells All cells come from pre-existing cells Cells are organized Organelles- compartments that perform different functions in the cell Cells can be prokaryotic or eukaryotic Eukaryotes (Animals‚ plants‚ and fungi) Contain: Nucleus Membrane bound organelles Prokaryotes Nucleoid- region that contains DNA Flagellum Characteristics of Chloroplasts and Mitochondria (similar to Prokaryotic Cells)

All organisms that are considered to be alive must possess certain key characteristics or functions. These include: order‚ response to the environment‚ reproduction‚ growth and development‚ regulation‚ energy processing and evolution. Since we recognize life by what living things do‚ these seven characteristics serve to define life. Organisms consist of one or more cells and while they may be very complex they are highly organized and coordinated. Inside each cell‚ atoms make up molecules.

7-1‚ 7-2 Cell Structures and Function cell theory- all living things are composed of cells‚ cells are the basic units of structure and function in living things‚ new cells are produced from existing cells. prokaryote- smaller and simpler than eukaryotes‚ do not contain nuclei‚ are part of the Bacteria domain‚ are unicellular‚ are autotrophs or heterotrophs eukaryote- cells with nuclei and contain specialized structures called organells. All plants‚ animals and fungi are eukaryotes. Part of the

Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE

*What is Biochemistry?* * Biochemistry also known as Chemistry of life is the study of chemical substances and vital processes occurring in living organism. Biochemistry governs all living organisms and living processes. * Study of chemical processes in living organisms‚ including‚ but not limited to‚ living matter. * Biochemistry is the science dealing with the chemical composition and chemical reactions happening within‚ and between the living cells of all organisms. → The
