Biology - topic 6 Flashcards

Transports water and mineral ions from roots to leaves. Made of dead cells and strengthened with lignin.

Transports dissolved sugars and other nutrients throughout the plant. Made of living cells.

Small openings on the underside of leaves that allow gas exchange (CO2 in, O2 out).

Control the opening and closing of stomata to regulate water loss and gas exchange.

Organelles in plant cells where photosynthesis occurs. Contain chlorophyll to absorb light energy.

Specialised cells in roots that increase surface area for water and mineral absorption.

Layer of cells in leaves packed with chloroplasts for maximum photosynthesis.

Layer of cells in leaves with air spaces to allow gas exchange.
