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

  1. The plant cell model describes the common structures of plant cells.
  2. Some of these structures are common with animal cells, such as the cytoplasm, cell membrane, nucleus and mitochondria.
  3. Plant cells have additional structures, i.e. the cell wall, chloroplasts and vacuole; each has a specific function.
  4. Specialised cells in plants have shapes, sizes and structures that are adapted for the jobs the cells do.
  5. 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.

It is useful to mention that not all plant cells contain all of the sub-cellular structures in the plant model cell.

6 Questions

Q1.
Match the specialised cell to their function.
Correct Answer:root hair cell,cover the outer surface of roots and absorb water and minerals

cover the outer surface of roots and absorb water and minerals

Correct Answer:xylem,transport water upwards from roots to leaves

transport water upwards from roots to leaves

Correct Answer:guard cell,control if the stomata are open or closed

control if the stomata are open or closed

Correct Answer:phloem,transport glucose and amino acids up and down the plant

transport glucose and amino acids up and down the plant

Q2.
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
Correct answer: 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
Q3.
Match the feature of the palisade cell to the advantage they provide.
Correct Answer:have a column shape,can be packed together

can be packed together

Correct Answer:found at the top of the leaf,absorb lots of light energy

absorb lots of light energy

Correct Answer:contain lots of chloroplasts,where photosythesis occurs

where photosythesis occurs

Q4.
Xylem cell walls are thickened with ; this provides strength to the hollow tubes.
Correct Answer: lignin, lignins
Q5.
Which of these statements about phloem are correct?
have sieve plates which provide energy to move glucose
Correct answer: phloem are attached to companion cells that provide energy to move glucose
transport water from roots to leaves
Correct answer: contain few sub-cellular structures so more glucose can can travel through
Q6.
What happens to guard cells at night time?
they absorb water by osmosis to become turgid
Correct answer: they lose water to become flaccid
Correct answer: stomata close to stop water leaving
stomata open to allow water to evaporate
