Question

question: organelles are specialized structures that perform various functions in the cell. what are the functions of the organelles in an animal cell?

1. label: locate each organelle in the animal cell. you can choose organelles from the dropdown menu or click on them directly. label the organelles in the diagram below.

1. match: read about each organelle. then match each organelle to its function/description.

__ cytoplasm a. structure that organizes motion of chromosomes.
__ lysosome b. stack of membranes that packages chemicals.
__ mitochondria c. membrane that surrounds and protects the nucleus.
__ centriole d. membrane that surrounds and protects the cell.
__ endoplasmic reticulum e. sac filled with digestive chemicals.
__ vacuole f. structures that convert nutrients to energy.
__ cell membrane g. passageways where chemicals are made.
__ nucleus h. everything between the nuclear membrane and the cell membrane.
__ cytoskeleton i. structure that manufactures ribosomes.
__ ribosome j. structure that contains dna and regulates genes.
__ nuclear membrane k. package created by the golgi apparatus.
__ golgi apparatus l. small structure that synthesizes proteins.
__ vesicle m. sac that stores water, nutrients, or waste products.
__ nucleolus n. tubules and filaments that give the cell its shape.

Explanation:

To solve the match - up of organelles and their functions, we analyze each organelle:

• Cytoplasm: It is the area between the nuclear membrane and the cell membrane, so it matches H.
• Lysosome: A sac filled with digestive chemicals, so it matches E.
• Mitochondria: Converts nutrients to energy, so it matches F.
• Centriole: Organizes the motion of chromosomes, so it matches A.
• Endoplasmic reticulum: Passageways for chemical production, so it matches G.
• Vacuole: Stores water, nutrients, or waste, so it matches M.
• Cell membrane: Surrounds and protects the cell, so it matches D.
• Nucleus: Contains DNA and regulates genes, so it matches J.
• Cytoskeleton: Tubules and filaments for cell shape, so it matches N.
• Ribosome: Synthesizes proteins, so it matches L.
• Nuclear membrane: Surrounds and protects the nucleus, so it matches C.
• Golgi apparatus: Stacks of membranes that package chemicals, so it matches B.
• Vesicle: Package from the Golgi apparatus, so it matches K.
• Nucleolus: Manufactures ribosomes, so it matches I.

Answer:

• Cytoplasm - H
• Lysosome - E
• Mitochondria - F
• Centriole - A
• Endoplasmic reticulum - G
• Vacuole - M
• Cell membrane - D
• Nucleus - J
• Cytoskeleton - N
• Ribosome - L
• Nuclear membrane - C
• Golgi apparatus - B
• Vesicle - K
• Nucleolus - I
