Describe the function of each organelle.Nucleus

Answer:

The nucleus contains the cell’s DNA and controls the cell’s activities.

15

Ribosome

Answer:

Ribosomes make proteins by assembling amino acids according to genetic instructions.

16

Endoplasmic reticulum

Answer:

The endoplasmic reticulum helps make and transport materials in the cell; rough ER processes proteins, and smooth ER makes lipids.

17

Golgi apparatus

Answer:

The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport.

18

Describe the function of each organelle.Vacuoles

Answer:

Vacuoles store water, nutrients, and waste. In plant cells, the central vacuole also helps maintain cell pressure.

19

Lysosomes

Answer:

Lysosomes use digestive enzymes to break down waste and worn-out cell parts.

20

Mitochondrion

Answer:

The mitochondrion carries out cellular respiration to produce ATP, a usable form of energy for the cell.
