Animal Cell Quiz for Grade 6

Energy Production

• Mitochondria are the powerhouse of the cell, responsible for converting nutrients into usable energy in the form of ATP (adenosine triphosphate).
• They play a crucial role in cellular respiration, which involves the breakdown of glucose and oxygen to produce energy.

Regulation of Cell Membrane

• The plasma membrane regulates the entry and exit of substances, maintaining homeostasis.
• It is selectively permeable, allowing certain molecules to pass while restricting others, contributing to the cell's internal environment.

Protein Synthesis

• Ribosomes are the organelles dedicated to protein synthesis, translating genetic information from mRNA into polypeptides.
• They can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, facilitating protein assembly.

Lysosomes Function

• Lysosomes contain digestive enzymes that break down waste materials, cellular debris, and foreign invaders like bacteria.
• They also play a key role in autophagy, the process of recycling cellular components to maintain cell health.

Genetic Material Storage

• The nucleus houses the cell's genetic material (DNA), organized into chromosomes.
• It serves as the control center for cellular activities, regulating gene expression and replication.
