Adaptations Of Leaves Flashcards
Large surface area
=more gas exchange and photosynthesis
Leaves have no overlap
=efficient use of leaves for photosynthesis/light can reach all leaves
Thin
= large sa:v ratio for gaseous exchange
Transparent cuticle and epidermis
allows more light to reach the palisade cells for photosynthesis
Long, narrow palisade mesophyll cells
=can be packed tightly together for maximum absorption of light by chloroplasts
Palisade mesophyll cells packed with chloroplasts
= absorbs as much light as possible
Numerous stomata
=shorter distance for gaseous exchange
Stomata open and close
=efficient gas exchange without loss of water
Many air spaces in spongy mesophyll
=allows air to reach all cells
Network of xylem
=transports water from roots to leaves for quick photosynthesis
Network of phloem
=transports sucrose and amino acids to other structures of the plant quickly
