- flower
-
- Which of these processes do plants use to make glucose?
- respiration

- ribosomes
- chloroplasts
- nucleus
- mitochondria ✓
-

Exit quiz
- Match the specialised cell to their function.
- root hair cell⇔cover the outer surface of roots and absorb water and minerals ✓
- xylem⇔transport water upwards from roots to leaves ✓
- guard cell⇔control if the stomata are open or closed ✓
- phloem⇔transport glucose and amino acids up and down the plant ✓
- Which is not true for root hair cells?
- contain lots of mitochondria to transfer energy for active transport
- contain a large permanent vacuole to store water
- have broken down cell ends to create hollow tubes so water can flow easily ✓
- large surface area to increase absorption of water and mineral ions
-
- Match the feature of the palisade cell to the advantage they provide.
- have a column shape⇔can be packed together ✓
- found at the top of the leaf⇔absorb lots of light energy ✓
- contain lots of chloroplasts⇔where photosythesis occurs ✓
- Xylem cell walls are thickened with ______ ; this provides strength to the hollow tubes.
- 'lignin' ✓
- Which of these statements about phloem are correct?
- have sieve plates which provide energy to move glucose
- phloem are attached to companion cells that provide energy to move glucose ✓
- transport water from roots to leaves
- contain few sub-cellular structures so more glucose can can travel through ✓
-
- What happens to guard cells at night time?
- they absorb water by osmosis to become turgid
- they lose water to become flaccid ✓
- stomata close to stop water leaving ✓
- stomata open to allow water to evaporate

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 subcellular structure made from cellulose fibres that strengthens the cell and supports the plant.
Chloroplast - A subcellular structure that contains the green pigment chlorophyll, which absorbs light for photosynthesis.
Permanent vacuole - A subcellular structure filled with cell sap that helps keep the cell turgid.
Photosynthesis - A chemical reaction that plants use to make glucose, taking place in the chloroplasts.
Active transport - The net movement of particles from a low to high concentration, against a concentration gradient, using energy.
