they are very small and do not need energy. 2. a) Root hair cells are found at the root of plants. They help plants to absorb water and mineral ions from soil efficiently. Mesophyll cells are found in leaves. They carry out gas exchange and photosynthesis in plants. b) Root hair cells are adapted to increase the rate of diffusion of water and mineral ions from soil to be as quick as possible. The

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1

Roberts Energy‚ Metabolism‚ and Cells Photosynthesis is the process that pretty much every organism on earth needs‚ because of the nutrients produced which is needed in order to live. Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis‚ it takes the sun’s energy and chlorophyll found in chloroplasts in the green leaves of plants‚ to turn inorganic

is skyrocketing‚ between 2000 and 2007 three new dinoflagellate families‚ 22 new genera‚ and 87 new species were described (Hoppenrath‚ 2012). Many dinoflagellates are primary producers of food in the aquatic food webs (Faust‚ 2014). They use photosynthesis or the Sun for their energy. Although other dinoflagellates are heterotrophs and some are both! Most of them have protective cellulose plates that become encrusted with a hard‚ unreactive‚ colorless compound.

The species of green plant leaves that were used in this experiment were Hedera helix‚ commonly known as English Ivy. These plant leaves have both

their chloroplasts are often studied in order to understand the process of photosynthesis in more detail. Suppose you have a plant with no chlorophyll (it is an albino plant). Describe its appearance and the effect this would have on the plant. Albino plants are white because they lack chlorophyll in their leaves. Since plants use chlorophyll for photosynthesis‚ having no chlorophyll is a problem. An albino plant can’t make its own food so it must eat off other plants. a. Chloroplasts are the
