Cells Cell Theory and Organelles

The purpose of the cell wall in plants is to -

• Store DNA and proteins for the cell.
• Control what crosses into and out of the cell.
• Provides structure and support for the cell.
• Send chemical signals to neighboring cells.

Plant cells are different from animal cells because they are usually -  

• Circular in shape, contain lysosomes, and have mitochondria.
• Circular in shape, contain ribosomes, and have centrioles.
• Rectangular in shape, contain a small vacuole, and have mitochondria.
• Rectangular in shape, contain a large vacuole, and have chloroplasts.

Which organelle requires light in order to perform its function?

• A centriole, because it performs cell division that is encouraged by light.
• A Golgi apparatus, because it packages proteins by light triggered reactions. 
• A mitochondrion, because it performs respiration with its light membrane.
• A chloroplast, because it performs photosynthesis with its light absorbing pigments.
