Plant transport no heart, no blood and no circulation, but plants do need a transport system to move food, water and minerals around they use two different systems - xylem moves water and solutes from the roots to the leaves - phloem moves food substances from leaves to the rest of the plant. Answers to questions on plant structure and function in in chapter 6 of igcse & gcse biology by d g mackean, for teachers and students. Leaves are green as they contain 7 in addition to a tap root, a banyan plant possesses roots arising from branches these roots are meant for 8 the vegetables such as carrot and radish that you eat are modified. Structure of a leaf functions of leaves the function of a leaf is photosynthesis - to absorb light and carbon dioxide to produce carbohydrates. Lungs, where carbon dioxide leaves the blood and enters the air sacs when we breathe out, the external intercostal muscles relax and the ribs move down and in the diaphragm muscles relax, and the diaphragm returns to a dome shape answers. Plant nutrition 61 photosynthesis it is waxy to prevent waters staying on the leaves no enough magnesium - leaves turn yellow igcse, biology, plant, photosynthesis, nlcsjeju, limiting factor, science advertisements discussion.
Plant parts vascular tissue - tube like elongated cells through which food and other materials are transportedlarger plants have special vascular tissues in their stems and leaves that transport materials. Tropical rainforest facts leaves have drip tips that shed moisture quickly after heavy downpours trees are tall with few branches as they strive to get to the light and photosynthesise shallow. In igcse examinations the starch in the tubers is changed back to the sucrose, and transported in the phloem to the growing stems and leaves this will continue until the leaves and stems are above ground and start to photosynthesise.

Measuring rate of water uptake by a plant shoot using a potometer class practical in this activity the rate of water uptake 1 use shoots from a shrub or tree with leaves that have thin waxy cuticles, such as beech, lilac, spirea leaves with thicker waxy cuticles. Leaf structure and adaptations for photosynthesis: a understanding for igcse biology 220 the leaf is the organ in a plant specially adapted for photosynthesis you need to understand the structure of the tissues in a leaf together with their functions. Remind yourself of the structure of the leaf (section 2e - nutrition in flowering plants) remember that co 2 and o 2 diffuse in and out of leaves through stomata.

Transpiration the main force which draws water from the soil and through the plant is caused by a process called transpiration water evaporated from the leaves and causes a kind of suction which pulls water up the stem the water travels up the vessels and in the vascular bundles this flow of.
- Revise how xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant.
- Leaves that roll up in dry weather to increase humidity around stomata reducing air movement so humidity builds up and transpiration is with a pump (the heart) and valves to ensure one-way flow of blood07 - human transport biology notes igcse cambridge 2014 # 69 transport in humans.
- The structure of a leaf the leaves are the organ for photosynthesis it is where photosynthesis takes place the structures of leaves are adapted for efficient photosynthesis as shown in the table below.
Identifying the conditions needed for photosynthesis this protocol applies the technique of testing leaves for starch to plants that have been kept in controlled conditions in order to establish the conditions needed for photosynthesis to occur. Best answer: leaves are adapted for efficient photosynthesis in many ways for example: 1) leaves are broad, so there's a large surface area exposed to light 2) they're also thin, which means carbon dioxide and water vapour only have to travel a short distance to reach the. 1 cuticle: made of wax - waterproofing the leaf secreted by cells of the upper epidermis 2 upper epidermis thin and transparent - allows light to pass through.
