The figure below shows a section through a leaf. A leaf is designed for photosynthesis and this process provides a supply of simple sugars for a plant.

(a) State the adaptation of the chloroplasts to photosynthesis.
(b) Name a mineral ion in chloroplast.
(c) (i) Name the tissues that translocates sugar from the leaves to other parts of the plants.
(ii) How is the tissue named in c(i) above adapted to its function?
(d) Write a word equation for the process of photosynthesis.

(a) - Has grana with chlorophyll for trapping light for light stage of photosynthesis.
- Has stroma which contains enzymes for the dark stage of photosynthesis;
- It moves within the cell enabling it to receive maximum light for photosynthesis ;(mark the first two)
(b) Magnesium / nitrogen ;
(c) (i) Phloem ;
(ii) - It has companion cells with numerous mitochondria to provide ATP for the activetransport of nutrients ;
- It has numerous mitochondria to provideenergy for the active transport of food materials ;
- It has sieve plates with sieve pores for the passage of food materials ;
- It has cytoplasmic strands for the transport of food from one sieve tube ; to the other.
- Its cell organelles are pushed to the peripheryto give more room for the passage of food ;
- It has sieve tubes cells placed end to end for acontinuous flow of food ;
