Cells

• Whats inside the nucleus?

  DNA
• What is the cytoplasm?

  A jelly-like substance in which chemical reactions happen.
• What is the Cell membrane?

  this surrounds the cell and allows nutrients to enter and waste to leave it.
• What is the Mitochondria?

  help release energy that the cell can use for other tasks
• What are Chloroplasts?

  They enable photosynthesis
• What's the Cell wall?

  It is a part of the cell that provides structure.
• What is a Permanent Vacuole? 

  It's a part of the cell filled with cell sap that produces support to the cell
• Define how Muscle Cells are specialised to carry out their functions

  Special proteins to allow cells to slide passed eachother, and have lots of mitochondria for energy, they also store glycogen (a store of energy)
• Define how Root Hair Cells are specialised to do their functions

  Increased surface area, large permanent Vacuole to speed up water movement and lots of mitochondria for active transport.
• Define Tissue

  A group of Specialised cells working together to perform a specific task.
• Define Organ

  A group of tissues working together to perform a specific function
• Organ System

  A group of Organs working together to perform specific functions
• Cell differentiation

  The process where cells become specialised to perform a particular function.
• What are the risks and benefits of Therapeutic cloning?

  Benefits: Medical research, disease treatment Risks: concerns, misuse
• What do Special proteins in Muscle Cells help the cells to do?

  The special proteins in muscle cells allow them to slide past each other, enabling muscle contraction and relaxation.
• What is Cell differentiation?

  The process where cells become specialised to perform a particular function
• What's mitosis important for?

  Growth, Repair and Asexual reproduction
• What's the function of stem cells in embryos?

  Enable an entire organism to be developed.
• What's the function of stem cells in adult animal cells?

  Enable cells to be replaced. And to allow growth and repair to occur
• What is the function of embryos in meristems of plants?


  They enable plans to grow and develop
• What are Meristem cells?

  Undifferentiated cells
• What are the uses of meristem cells?


  Produce clones of plants quickly and economically and produce large numbers of identical plants for farmers.
• Identify why mitosis is important

  Growth and development of a multicellular organism and asexual reproduction
