Plant cells have chloroplasts (for photosynthesis), vacuole and a cell wall.
Chloroplasts absorb light energy for photosynthesis: water + carbon dioxide = oxygen + glucose. The water is taken in through the roots, and the carbon dioxide through the stomata pores. These pores also let oxygen escape, and even water, (transpiration).
Photosynthesis occurs mainly in the leaves. They are adapted for efficiency: 1. They have broad leaves, so there is a larger surface area to absorb light. 2. They are thin, so CO2, and H2O only have a short distance to travel, in order to reach the photosynthesising cells. 3. contain chlorophyll, the pigment that absorbs light. 4. network of veins for support, deliveringwater and nutrients to every part of the leaf, and taking away food. 5. they have stomata on the bottom, for gas exchange.
