Cell Structure

An organism that is composed of only one cell is called ---

• mutlicellular

• eukayotic

• unicellular

• prokaryotic

Number 1 is pointing to which organelle?

• chloroplast

• cell wall

• mitochondria

• central vacuole

Which structure is referred to as "the jelly" of the cell because it holds all the organelles and substances inside the cell?

• cytoplasm

• vacuole

• cell wall

• cell membrane

An organism that has its DNA NOT in a nucleus and NO membrane-bound organelles is called --- (OLD version of a cell-bacteria are this kind of cell)

• mutlicellular

• eukayotic

• unicellular

• prokaryotic

Which structure is referred to as "the guard" because it controls what substances move in and out of the cell?

• cell wall

• cell membrane

• vacuole

• nucleus

Which structure is referred to as "the storage tank" because it holds water, minerals, wastes and other substances in the cell? (Plant cells have a LARGE central one to store the extra water a plant needs.)

• cell wall

• cell membrane

• vacuole

• nucleus

Number 2 is pointing to which organelle?

• mitochondria

• cell membrane

• cytoplasm

• cell wall

Which structure is referred to as "the passageways" of the cell because it carries materials throughout the cell? (It can be rough or smooth.)

• chloroplasts

• endoplasmic reticulum (ER)

• vacuole

• mitochondria

Which structure is referred to as "the brain" because it holds the DNA, or instructions for making proteins in the cell and controls its major activities?

• cell wall

• cell membrane

• vacuole

• nucleus

Number 10 is pointing to which organelle?

• mitochondria

• endoplasmic reticulum (ER)

• chloroplast

• nucleus
