Plant cells

• Plant cells contain the same organelle as animal cells and also chloroplast, permanent vacuole, cell wall.
• Chloroplasts use CO2, water and light energy to build glucose.
• Chloroplasts are surrounded by a double membrane filled with fluid (stroma) containing stacks of thylakoid membranes called grana (the site of photosynthesis).
• A vacuole consists of a membrane called the tonoplast, filled with cell sap. It's important in keeping the cell firm.
• The cell wall gives cells support and structure. It is made of the polysaccharide cellulose.
• The cell wall doesn't seal off completely. There's pores within the walls called (plasmodesmata) connecting two cells by their cytoplasm enabling the substance transport and exchange.
