Cell Organelles & Structures Review (Amoeba Sisters)

This cellular structure is found in all cells. It is an external structure that controls what goes in and out of the cell, and is responsible for maintaining homeostasis.

• Cell wall
• Nucleus
• Cytoplasm
• Cell membrane

Answer explanation

The cell wall is not found in all cells - only plants and some bacteria!

The nucleus is an internal structure (and only found in eukaryotes!).

Cytoplasm is also technically internal, and does not control what goes in and out of the cell.

Therefore, the correct answer is the cell membrane!

This cell structure is also external. It is part of most prokaryotic cells and some eukaryotic cells. It is important for cell structure and shape, and can also offer additional protection!

• Cell Wall

• Golgi body

• Cytoplasm

• Endoplasmic Reticulum

Answer explanation

The only external structure from this list is the cell wall - everything else is internal!

Remember, the cell wall is found in a lot of bacteria or prokaryotes, as well as in plant cells!

These cellular structures are found in some eukaryotic cells. They are paired organelles that come from the centrosome and are involved in cell division.

• Centrioles
• Mitochondria
• Lysosomes
• Ribosomes

Answer explanation

Centrioles are the only paired organelle from this list!

This structure is found in some eukaryotic cells (not all!) - it functions in photosynthesis and helps to make sugars (glucose).

• Mitochondria
• Ribosomes
• Nucleus
• Chloroplast

Answer explanation

This cellular structure is found in eukaryotic cells. It has many folds, and can help materials move through the cell. It also processes molecules and there is more than one type of it!

• Lysosome
• Endoplasmic reticulum
• Mitochondria
• Golgi apparatus

Answer explanation

This cell structure is responsible for assembling items sent from the ER. It then modifies, sorts, and packages those materials for delivery in the cell. It is found in eukaryotic cells.

• Endoplasmic reticulum
• Lysosome
• Ribosome
• Golgi apparatus

Answer explanation

This cellular structure is found in some eukaryotes and usually contains enzymes that can break down substances.

• Mitochondrion
• Endoplasmic reticulum
• Lysosome
• Ribosome

Answer explanation

This cellular structure is found in eukaryotes. It makes ATP through cellular respiration.

• Mitochondrion
• Ribosome
• Nucleus
• Chloroplast

Answer explanation

This structure is found in eukaryotic cells and is responsible for holding the cell's genetic material (DNA).

• ribosome
• nucleus
• mitochondrion
• endoplasmic reticulum

Answer explanation

This cellular structure can be found in all cells (prokaryotes and eukaryotes) and it functions to make proteins.

• Ribosome
• Golgi apparatus
• Nucleus
• Mitochondria
