Cell Organelles Quiz

organelles

little cell structures that have specific functions and are found in Eukaryotes

cell membrane

cells security system, surrounds and protects the cell, controls what enters and exits the cell

cytoplasm

gel-like substance inside the cell, where cell processes (chemical reactions) occur, 80% water

cell wall

tough structure that surrounds and protects plant cells, gives cells shape, made of cellulose

nucleus

control center of the cell, contains directions for the entire cell, DNA is found here, surrounded by a nuclear membrane

cholorplast

green organelle, in plant cells, photosynthesis, captures energy from the sun to make glucose

mitochondria

cell energy dam, stores and releases cell's energy, "powerhouse"

ribosomes

protein factories, make proteins, some float freely in the cytoplasm and others are attached to the ER

endoplasmic reticulum

cell's railroad track, moves material around in the cell, smooth-no ribosomes, rough-has ribosomes

golgi body

cell's post office, sorts and packages proteins into vesicles, vesicles deliver substances in the cell and also attach to the cell membrane to release materials to the outside

nucleolus

manufactors the proteins that make up the ribosomes, found in the nucleus

lysosome

cell's landfill, digest food molecules, cell wastes, and worn out cell parts

vacuole

temporarily stores food, water, waste; rather large in plan cells (vacuum stores dirt-like vacuole)

cytoskeleton

framework for the cell; helps to maintain shape or change shape of cell

tissue

a group of cells working together to perform a particular function

organ

two or more tissues working together to perform a function
