Plant cells: common structures and specialised cells
I can identify common structures of plant cells and relate each structure to its function.
Plant cells: common structures and specialised cells
I can identify common structures of plant cells and relate each structure to its function.
Lesson details
Key learning points
- The plant cell model describes the common structures of plant cells.
- Some of these structures are common with animal cells, such as the cytoplasm, cell membrane, nucleus and mitochondria.
- Plant cells have additional structures, i.e. the cell wall, chloroplasts and vacuole; each has a specific function.
- Specialised cells in plants have shapes, sizes and structures that are adapted for the jobs the cells do.
- Examples of specialised plant cells include root hair cells and palisade cells.
Common misconception
A palisade cell is not a specialised cell as it is used as the plant cell model. All plant cells contain chloroplasts.
Presentation outlines that the palisade cell is a specialised cell. Question in the check for understanding that is designed to show chloroplasts are not in root hair cells.
Keywords
Cell wall - A sub-cellular structure that is made from cellulose fibres and strengthens the cell and supports the plant.
Chloroplast - A sub-cellular structure that contains the green pigment chlorophyll, which absorbs light energy for photosynthesis.
Permanent vacuole - A sub-cellular structure that is filled with cell sap to help keep the cell turgid.
Photosynthesis - A chemical reaction that plants use to make glucose, which takes place in the chloroplasts.
Active transport - A process where particles move from low to high concentration against a concentration gradient, this requires energy.
