Cell Organelles - Sheet1

Question 1

mitochondrion

Answer 1

bean-shaped organelle that supplies energy to the cell and has its own ribosomes and DNA

Question 2

vacuole

Answer 2

organelle used to store materials such as food, water, enzymes and ions, that are needed by the cell

Question 3

lysosome

Answer 3

organelle that 1) contains enzymes, 2) defends a cell against bacteria and viruses, 3) breaks down damaged or worn-out cell parts

Question 4

centriole

Answer 4

small cylinder-shaped organelle made of protein tubes (microtubules) arranged in a circle; aids cell division (mitosis)

Question 5

cell wall

Answer 5

rigid structure that gives protection, support and shape to cells in plants, algae, fungi and bacteria

Question 6

chloroplast

Answer 6

organelle composed of many membranes used to convert solar energy into chemical energy

Question 7

cytoskeleton

Answer 7

network of proteins, such as microtubules and microfilaments, inside a eukaryotic cell that supports and shapes the cell

Question 8

nucleus

Answer 8

organelle composed of a double membrane, or phospholipid bilayer, that acts as the storehouse for most of a cell’s DNA

Question 9

endoplasmic reticulum

Answer 9

network of thin, folded membranes that produce, process and distribute proteins

Question 10

ribosome

Answer 10

organelle that links amino acids together to form proteins

Question 11

golgi apparatus

Answer 11

stack of flat, membrane-enclosed spaces containing enzymes that process, sort and deliver proteins

Question 12

vesicle

Answer 12

small organelle that contains and transports materials within the cytoplasm
