1) What common feature do both animal and plant cells share that controls what enters and leaves the cell? a) Cell wall b) Cell membrane c) Chloroplast d) Nucleus 2) Which organelle in both animal and plant cells acts like a factory breaking down sugars to release energy? a) Cytosol b) Nucleus c) Chloroplasts d) Mitochondria 3) What is the additional outer layer found only in plant cells that provides them stiffness and structure? a) Cell wall b) Cell membrane c) Chloroplast d) Mitrochondria 4) What unique organelle do plant cells have that enables them to perform photosynthesis? a) Cell wall b) Mitrochondria c) Chloroplasts d) Nucleus 5) Why don't animals, such as lions, have green colouring like plants? a) They have a thicker cell wall that hides green pigments. b) They lack chloroplasts which produce green colour through photosynthesis. c) Their mitochondria produce a different pigment colour. d) They have no cytosol to contain pigments. 6) What substance fills the interior of both animal and plant cells and contains organelles? a) Cell wall b) Nucleus c) Chloroplast d) Cytosol 7) How do chloroplasts and mitochondria work together in plant cells? a) Chloroplasts make sugars through photosynthesis; mitochondria convert sugars into usable energy. b) Mitochondria create sugars; chloroplasts convert sugars into energy. c) Both organelles produce energy directly without interaction. d) Both organelles store genetic information for the cell. 8) Which feature explains why celery stalks are stiff but animal muscle tissue feels floppy? a) Animal cells have thicker membranes making them flexible. b) The chloroplasts in celery provide stiffness. c) Presence of a cell wall in plant cells makes them stiff, unlike animal cells which lack cell walls. d) Muscle cells contain more cytosol which causes them to be floppy. 9) Which of the following is NOT a similarity shared between animal and plant cells? a) Nucleus b) Cell membrane c) Mitrochondria d) Cell wall 10) What role does the nucleus play in the cells? a) Produces energy by breaking down sugars. b) Stores the cell's genes and acts as an information database. c) Controls what enters and leaves the cell. d) Makes sugars through photosynthesis.
