Explain how materials enter and leave cells
WebAnimal cells do not have a cell wall (they can have a similar thing , called a cell cortex). So the vacuoles here play a more subordinate role - they still help with endo- and exocytosis. Also the are quite smaller than plant vacuoles and greater in number. And of course, there are some animal cells with no vacuoles at all. Hope that helps :) WebApr 26, 2024 · Explanation: So the reactants of photosynthesis are water, carbon dioxide and light energy. The water reaches the leaves via the xylem, which is found in the vascular bundle which is made of 2 main parts, the xylem (which carries water from the roots up the plant) and the phloem (which carries sugar from the leaves to the rest of the plant).
