• The development of techniques in genetic engineering and increased understanding of the molecular basis of cellular processes have led to the emergence of a new and exciting field of scientific research called biotechnology.
• TOPIC: CELL

  The cell is the basic structure of all living things
• TOPIC: CELL

  Sex cells reproduce by meiosis while somatic cells reproduce by mitosis.
• TOPIC: CELL

  Cells are of two types: prokaryotic and eukaryotic
• TOPIC: CELL

  Prokaryotes are cells that do not have a nuclear membrane or membrane-bound organelles
• TOPIC: CELL

  Bacteria and blue-green bacteria are examples of prokaryotes
• TOPIC: CELL

  Eukaryotes refer to most cells making up all other living organisms.
• TOPIC: CELL

  Cell membrane

  • a double layer of lipids that surrounds the cell, thus acting as a “gatekeeper," controlling what moves into and out of the cell.
• TOPIC: CELL

  Nucleus

  • separated from the cytoplasm by a thickened membrane that is more selective than the cell membrane.
• TOPIC: CELL

  Nucleus

  • It is the control center of the cell because it contains all the genetic information.
• TOPIC: CELL

  Cytoplasm

  • a semi fluid liquid that fills the cell and holds the components of a cell. It also holds dissolved nutrients such as amino acids and sugars.
• TOPIC: CELL

  Cytoplasm

  • It is a colloidal suspension that contains the highly organized structure called "organelles."
• TOPIC: CELL

  Cytoplasm

  • It contains all the chemicals for that particular cell to carry out its living activities.
• TOPIC: CELL

  Mitochondria

  • the powerhouse of the cell
• TOPIC: CELL

  Mitochondria

  • It is the site where energy (ATP) is obtained from food consumed and made available for the use of the cell
• TOPIC: CELL

  Chloroplast

  • the site of photosynthesis.
• TOPIC: CELL

  Plastids

  • store chlorophyll for the use of chloroplasts.
• TOPIC: CELL

  Lysosomes

  • Membrane-bound vacuoles in the cytoplasm, which contain hydrolytic enzymes that digest materials entering the cell
  • The enzymes are in the vacuoles so that they don't destroy the cell itself.
• TOPIC: CELL

  Smooth Endoplasmic Reticulum

  • does not have ribosomes attached and is the transportation system of the cell.
• TOPIC: CELL

  Rough Endoplasmic Reticulum

  • has ribosomes attached and also carries out cell transportation, but mainly of necessary protein materials needed by the cell
• TOPIC: CELL

  Golgi Apparatus

  • manufactures, synthesizes, stores, and distributes hormones, enzymes, and other protein materials needed by the individual cell or by the organism.
• TOPIC: CELL

  Peroxisomes

  • manufacture, store, and secrete oxidation enzymes needed by the cell.
• TOPIC: CELL

  Vacuoles

  • fluid-filled sacs which usually contain water, proteins, pigments, organic acids, or metabolic wastes. Some are active in cell metabolism, while others act as storage containers.
• TOPIC: CELL

  Basal bodies

  • short, cylindrical microtubules which play a role in cell movement by directing the formation of cilia and flagella.
• TOPIC: CELL

  Cell wall

  • a nonliving, inflexible, outer component of plant cells which supports and protects the cell. The main component is often cellulose.
• TOPIC: CELL

  Centrioles

  • small cylindrical bodies which lie just outside the nucleus in animal cells in a specialized area of cytoplasm.
• TOPIC: CELL

  Centrioles

  • They play a role in cell division and in cell motility.
• TOPIC: CELL

  Nucleolus

  • a dark-straining organelle within the nucleus which contains RNA, proteins, and some DNA.
