Studied by 5 peoplePhotosynthesis
the process by which plants convert carbon dioxide and water into sugars using sunlight as energy in the presence of chlorophyll.
Light intensity
The limiting factor on the rate of photosynthesis besides, carbon dioxide concentration and temperature
cuticle
protects the epidermis and prevents excessive water loss through evaporation.
Guard Cells
Bean-shaped, chloroplast-containing cells located in the lower epidermis.
Upper epidermis
single layer of irregular, closely packed cells covered by a layer of waxy cuticle.
Palisade mesophyll
cells that are columnar in shape and closely packed
Spongy mesophyll
cells that are irregular in shape with numerous intercellular air spaces around them to allow for fast diffusion of carbon dioxide
Vascular Bundles
The name given to xylem and phloem tissues collectively
Stomata
Structures in plants, opened during the day for carbon dioxide intake and closed during the night to minimise water loss through transpiration.
Flaccid
The appearance of guard cells when there is excessive water loss, even during the day, and they lose turgor
