Cell Structure

• Organelle: any of a number of organized or specialized structures within a living cell.
• Cell membrane is a selectively permeable barrier that controls the movement of substances in and out of the cell
• The nucleus contains genetic material (DNA) which controls all activities of the cell
• Ribosomes are responsible for protein synthesis
• Mitochondria produce energy through respiration
• Chloroplasts contain chlorophyll, which absorbs light to make food during photosynthesis
• Chloroplasts contain chlorophyll, used to make food from sunlight
• Vacuoles store water, waste products, pigments, and enzymes
• Vacuoles store water or waste products
• Cytoplasm the gelatinous liquid that fills the inside of a cell
• Bacteria cells are prokaryotic cells, meaning they do not have a nucleus.
• Animal and Plant cells are eukaryotic cells. They have a nucleus, cytoplasm and cell membrane.
• Cell walls give plant cells structure and stop them bursting when there's too much pressure on them.
• Ribosomes are the cellular machinery responsible for making proteins.
• Bacteria cells have a circular strand of DNA which provides them with the genes they need to survive and reproduce
• Cell organization: organelles - cells - tissues - organ systems - organisms
• differentiation: the process by which a cell becomes specialised for its function
• mitosis: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth
• What is a tissue?

   a group of cells that are similar in structure and are organized together to perform a specific task
• What are organelles found in both animal and plant cells? Describe the functions

  Mitochondria, cell membrane, nuclues, cytoplasm
• What is an Organ?

  a collection of tissues that structurally form a functional unit specialized to perform a particular function
