Introduction to Eukaryotic Organelles quiz Flashcards

Ribosomes are molecular machines that build proteins through a process called translation.

Ribosomes are considered non-membranous organelles.

Ribosomes can be found free-floating in the cytoplasm or attached to the rough endoplasmic reticulum.

The process is called translation.

Free ribosomes float in the cytoplasm, while attached ribosomes are bound to the rough endoplasmic reticulum.

The cytoplasm is the area inside the cell but outside the organelles.

The rough ER is known for having ribosomes attached to its surface and being involved in protein secretion.

Vesicles are tiny membrane bubbles that carry materials between organelles.

The nucleus, endoplasmic reticulum, Golgi apparatus, and transport vesicles are involved in protein secretion.

The two main functions are protein secretion and cellular digestion.

The Golgi apparatus modifies, sorts, and packages proteins for secretion.

The nuclear envelope encloses the nucleus and is part of the endomembrane system involved in protein secretion.

Lysosomes and peroxisomes are primarily involved in cellular digestion.

The central vacuole stores nutrients and waste products and helps maintain turgor pressure in plant cells.

Mitochondria are involved in energy production through aerobic respiration.

Nucleoli are present during interphase.

Compartmentalization allows for increased efficiency and specialization of metabolic processes, reducing interference between different biochemical pathways and enabling more complex regulation.

Without the specific pairs provided, it's difficult to determine the incorrect match. However, an example of an incorrect match would be glycolysis occurring in the mitochondria, as it actually occurs in the cytoplasm.

The nuclear envelope of a eukaryotic cell consists of a double membrane that encloses the nucleus, separating it from the cytoplasm, and contains nuclear pores for transport of molecules.

Without the specific diagram, it's not possible to determine which organelles are labeled 'g'. However, common organelles include centrioles, lysosomes, ribosomes, and mitochondria.

Processes such as glycolysis and translation by free ribosomes take place in the cytoplasm of a cell.

The cytoplasm of an unfertilized egg contains nutrients, organelles, and molecular machinery necessary for early development post-fertilization.

The rough endoplasmic reticulum is involved in the synthesis of proteins destined for secretion, membrane insertion, or lysosomes, and it is studded with ribosomes.

The endoplasmic reticulum, particularly the smooth endoplasmic reticulum, is a fine network of tubular structures.

Yes, key structures of a plant cell include the cell wall, chloroplasts, central vacuole, nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes.

Connector proteins, such as those in cell junctions, help to link cells together, providing structural support and facilitating communication between cells.

Without the specific diagram, it's not possible to determine which organelle is labeled 'g'. However, common organelles include the cytoplasm, cell wall, cell membrane, and vacuole.

Without the specific diagram, it's not possible to determine the function of the organelles labeled 'e'. However, small, dark organelles could be ribosomes, which are involved in protein synthesis.

Without the specific figure, it's not possible to determine the exact order. However, a common sequence might be the nucleus, cytoplasm, cell membrane, and cell wall (in plant cells).

Lysosomes and centrioles are organelles typically not found in plant cells.

Glycolysis and translation by free ribosomes are processes that take place in the cytoplasm.
