Cell Structures and Function Video

Which external cell structure is found in all cells, both prokaryotic and eukaryotic, and is responsible for controlling what enters and exits the cell, thereby maintaining homeostasis?

• Cell Wall

• Cell Membrane

• Cytoplasm

• Endoplasmic Reticulum

This external structure provides shape and additional protection to the cell. It is found in most prokaryotic cells and some eukaryotic cells, such as plant cells, but not in animal cells.

• Cell Membrane

• Cytoskeleton

• Cell Wall

• Centrioles

These structures are found in eukaryotic cells, specifically animal cells, but not plant cells. They come in pairs from the centrosome and are actively involved in cell division by organizing spindle fibers.

• Chloroplasts

• Centrioles

• Cytoskeleton

• Ribosomes

This organelle is found in some eukaryotic cells, such as plant cells, but not animal cells. Its primary function is to make sugar through the process of photosynthesis.

• Mitochondria

• Chloroplast

• Nucleus

• Vacuole

What is the main function of the Golgi apparatus?

• Stores water and waste products

• Produces ATP through cellular respiration

• Modifies, sorts, and packages materials for delivery

• Synthesizes proteins

The _____________ acts as the primary processing floor, where proteins are initially folded and modified after being built by the ribosomes.

• Rough Endoplasmic Reticulum

• Nucleus

• Cell Wall

• Mitochondrian

Which organelle contains enzymes that break down substances within the cell?

• Ribosome

• Lysosome

• Nucleus

• Vacuole

What is the primary role of the mitochondrion?

• Houses the cell's DNA

• Stores materials like water and proteins

• Makes ATP through cellular respiration

• Modifies and packages proteins

Which organelle is found in eukaryotic cells, houses the cell's DNA, and controls its activities?

• Ribosome

• Mitochondrion

• Nucleus

• Golgi apparatus
