B2.1 Cell Structure Flashcards
List features only present in plants
- Cell wall
- Large vacuole
- Chloroplasts
List the features in an animal cell
- Cell membrane
- Cytoplasm
- Nucleus
- Mitochondria
List the features in a plant cell
- Mitochondria
- Chloroplasts
- Cell wall
- Cell membrane
- Cytoplasm
- Nucleus
- Large vacuole
Functions of a cytoplasm
- a jelly-like substance where chemical reactions take place
Functions of a nucleus
- Contains genetic material in the chromosomes
- Controls how a cell grows and works
- Controls cell division
Functions of a vacuole
- Used for storage of some materials
- Supports the shape of the cell
- If there is not enough cell sap in the vacuole, plant may be wilt
Functions of a chloroplast
- Contains green pigment-chlorophyll-which absorbs sunlight for photosynthesis
Functions of a cell membrane
- Holds the cell together
- Controls substances entering and leaving the cell
Functions of a cell wall
- Made of cellulose, which gives the cell extra support
- Defines its shape
Function of a sperm cell
Travels to the egg cell for fertilisation and carries genetic information for the egg cell
Function of a palisade mesophyll cell
Photosynthesis
Function of a red blood cell
Transports oxygen from the lungs to the rest of the body
Function of a ciliated cell
Performs the movement of mucus in the trachea and bronchi
Function of a root hair cell
Absorbs water and uptakes minerals
How is a root hair cell adapted to its function?
- elongated shape of the cells increases the surface area available for absorption of water and minerals
- Long projections –> increase the surface area that the plant can use to absorb water and minerals
