How are cells different from each other?
Keywords:
  • Root hair cell: Have a large surface area to absorb water and nutrients. RHC have no chloroplasts as light does not get to them (1)
  • Function: The 'job' / what something does. (1)
  • Red blood cell: a rounded shape to allow it to flow smoothly. Is red due to the iron compound used to carry oxygen. RBC have no nucleus and a biconcave cross section to increase oxygen capacity. (1)
  • Elodea cell: Elodea is a type of pond plant, the cells have lots of chloroplasts to capture light for the process of photosynthesis. (1)
  • Ciliated cell: Have hair like structures to move substances around. (1)
  • Adapted: How something is different. (1)
  • Organelle: Part of a cell (1)
  • Root hair cell: A cell found on the side of roots. (1)
  • Plant: A living organism which makes its own food. (1)
  • Red blood cell: A cell used to carry oxygen. (1)
  • Ciliated cell: A cell with hairs on. (1)
  • Elodea cell: A type of pond plant. (1)
  • Animal: A living organism which feeds on other orgasms for food. (1)

W the similarities and differences between plant and animal cell: - Plant and animal cells both have: cell membrane; cytoplasm; nucleus; mitochondria & ribosomes. - Only plant cells have: cell wall; permanent vacuole and sometimes chloroplasts. Compare an animal and plant cells.

Draw a human cheek cell as a standard animal cell. Double bubble to compare.

A Students to sort diagrams (or photos for higher ability) of animal and plant cells based on their characteristics. - Root hair cell - Red blood cell - Elodea cell - Ciliated cell How are you able to tell the difference between an animal and plant cell?

Sorting photos of cell diagrams

W That cells have special characteristics, different organelles and shape, in order to fulfill their function. Give 3 examples of specialised plant or animal cells. How are they different to other cells and how does this help the cells complete their specialist function?

Use Specialised cells powerpoint.

W Root hair cells have a large surface area to absorb water and nutrients. RHC have no chloroplasts as light does not get to them. What is the function of a root hair cell and how is the cell specialised to do this?

W Red blood cells have a rounded shape to allow it to flow smoothly. Is red due to the iron compound used to carry oxygen. RBC have no nucleus and a biconcave cross section to increase oxygen capacity. What adaptations do red blood cells have in order to efficiently carry oxygen around the body?

W Elodea cell have lots of chloroplasts to capture light. What special adaptation do Elodea have? Why do they have this?

W Ciliated cells have hairs on them to move substances around. Why do ciliated cells have hairs?

W NB: Do not use a palisade cell as this will be used in 3B.
