Bounded by a nuclear membrane, this organelle contains DNA (deoxyribonucleic acid), the hereditary information of the cell.
RIBOSOME
GOLGI APPARATUS
NUCLEUS
PLASMA MEMBRANE
In the cytoplasm, this organelle assists in the assembly of
amino acids into proteins.
NUCLEUS
LYSOSOME
MITOCHONDRIA
RIBOSOMES
These vesicles from a Golgi apparatus contain digestive enzymes that break down food, cellular debris, and foreign invaders such as bacteria.
RIBOSOMES
CHLOROPLAST
ENDOPLASMIC RETICULUM
LYSOSOMES
Identify the organelle presented in the picture.
CHLOROPLAST
MITOCHONDRIA
GOLGI APPARATUS
SMOOTH ER
This organelle appears as a series of maze-like channels, often closely associated with the nucleus. It is responsible for the production of glycoproteins and the synthesis of lipids and hormones.
