Stored in the cytoplasm
Starch and crystals kept in the cell are called inclusions.
A cell’s pantry
A kitchen keeps flour and other supplies on shelves. Cells also store materials.
Where might a plant cell keep its stored starch?
What this lesson covers
The idea
Materials stored in the cytoplasm, namely starch in plant cells and crystals of calcium oxalate or silica in some plant cells, are called cell inclusions.
A cell’s pantry
A kitchen keeps flour and other supplies on shelves. Cells also store materials.
Where might a plant cell keep its stored starch?
- In the cytoplasm
- Outside the cell
- It cannot store anything
Find the stored materials
Choose a material. See where it is stored in the cell.
Cell inclusions
Materials stored in the cytoplasm: starch in plant cells, and crystals of calcium oxalate or silica in some plant cells, are called cell inclusions.
Inclusions are stored materials, not working organelles.
- Inclusion | Found in
- Starch | plant cells
- Calcium oxalate crystals | some plant cells
- Silica crystals | some plant cells
Notes
Materials stored in the cytoplasm are cell inclusions: starch in plant cells, and calcium oxalate or silica crystals in some plant cells.
Check yourself
Which is a cell inclusion?
Where are cell inclusions found?
Which are examples of crystals found as cell inclusions?
Which cells store starch as an inclusion?
- Starch stored in a plant cell — correct. Yes.
- The cell membrane. The membrane is the boundary.
- The nucleus. The nucleus is an organelle.
- In the cytoplasm — correct. Yes.
- Outside the cell. They are inside the cell.
- Only in the nucleus. They are in the cytoplasm.
- Calcium oxalate and silica — correct. Yes.
- Salt and sugar. Those are not the examples listed.
- Starch and glucose. Starch is a stored food, not a crystal.
- Plant cells — correct. Yes.
- Only bacterial cells. NCERT names plant cells.
- No cells. Plant cells store starch.
