PHOTOSYNTHESIS (2):Adaptations

Question 1

Name the 9 adaptations of a leaf for photosynthesis?

Answer 1

Palisade layer, Spongy Mesopyhl layer, flat and thin shape, Upper Epidermis, Stomata, Xylem, Phloem, RHC

Question 2

How is the palisade layer adapted for photosythsis?

Answer 2

top of the leaf, Contains hundreds of chlorophyll, maximises absorbed sunlight

Question 3

How is the spongy mesophyll layer adapted for photosynthesis?

Answer 3

loosely packed allows for faster diffusion of gases through it to the palisade cells, allows gases out easeir

Question 4

How is the leaf being flat and thin useful for photosynthesis?

Answer 4

Flat-Large surface area for maximum light energy absorption

Thin-Shorter diffusion pathway/distance

Question 5

How is the upper epidermis adapted for photosynthesis?

Answer 5

Thin and transparent allows more light to reach palisade cells

Question 6

How is the xylem adapted for gas exchange?

Answer 6

Transports water and mineral irons from the roots to the leaves

Question 7

How is the phloem adapted for gas exchange?

Answer 7

Transports the product(glucose) of photosynthesis away from the mesophyll cells to other tissues and organs of the plant(For storage)

Question 8

How is the Root Hair Cell adapted for photosynthesis?

Answer 8

increases surface area of the roots

                         to maximise absorption of water and minerals
