Animal Cell Facts Quiz

Animal Cell Facts

• Defined by Schwann, all animals are composed of cells.
• Contains centrioles essential for cell division, absent in plant cells.
• Characteristically oval in shape.
• Structure comprises a cell membrane, lacking a cell wall.
• Humans are composed of animal cells since they fall under the animal kingdom.
• Features small vacuoles for storing water and other substances.
• Mitochondria convert oxygen into usable energy for the cell.
• Size varies from approximately 1 to 100 micrometers.
• Classified as eukaryotic cells with a defined nucleus.
• Reproduces through mitosis, ensuring genetic continuity.
• Originates from pre-existing animal cells, indicating cellular lineage.
• Capable of self-destruction via apoptosis if dysfunction occurs.
• Cytoplasm maintains cell shape and houses the cytoskeleton.
• Nucleus can occupy any position within the cell.
• Ribosomes synthesize proteins, essential for cellular function.
• Ribosomes may be attached to the endoplasmic reticulum or free-floating.
• Nucleolus within the nucleus produces ribosomal RNA.
• Lysosomes play a critical role in eliminating harmful bacteria.
• Nucleus holds all genetic material (DNA) for cellular functions.
• Chromatin refers to the form of DNA stored in the nucleus.
• Golgi apparatus is responsible for transporting and packaging cellular components.
• Smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis.
• Fundamental to all animals, supporting various physiological functions.
• Nuclear envelope secures the nucleus and nucleolus position.

Plant Cell Facts

• Plant cells have a distinctive rectangular shape.
• Essential structural unit for all plants with specific functions.
• Contains chloroplasts that convert sunlight into energy through photosynthesis.
• Surrounded by a protective cell wall that maintains shape and integrity.
• Beneath the cell wall lies the cell membrane, regulating substance movement.
• Typically features a single large vacuole occupying significant cell space.
• Involved in synthesizing sugars and carbohydrates crucial for plant life.
• Contributes to the availability of food resources for humans, e.g., potatoes and green beans.
• Requires sunlight exposure for growth and energy conversion processes.
• Shares similarities with animal cells, notably mitochondria, cell membrane, and cytoplasm.
• Cytoplasm stabilizes organelles within the cell.
• Contains ribosomes for protein production, necessary for growth and repair.
• The endoplasmic reticulum aids in intracellular transportation.
• Features two types of endoplasmic reticulum: smooth and rough, each serving distinct functions.
• Golgi apparatus also present for cellular transport and packaging duties.
• Mitochondria convert chemical energy into utilize energy forms for cell activity.
• Nucleus serves as the control center, housing DNA essential for cell regulation.
• Nucleolus found within the nucleus is involved in RNA synthesis, crucial for protein synthesis.
