Based on the analysis of the provided diagram, here is the correct labeling for each numbered organelle in both the animal and plant cells:
1.
Cell Membrane (Plasma Membrane): This is the outer boundary of the animal cell, controlling what enters and exits the cell.
2.
Cell Wall: This is the rigid outer layer of the plant cell, providing structural support and protection.
3.
Ribosomes: These are small, dot-like structures found in the cytoplasm of both cells, responsible for protein synthesis.
4.
Lysosome/Peroxisome: These are small, membrane-bound sacs that contain digestive enzymes to break down waste materials and cellular debris. Lysosomes are more prominent in animal cells, while peroxisomes are found in both.
5.
Mitochondrion: This is the oval-shaped organelle with internal folds (cristae), known as the powerhouse of the cell because it generates energy (ATP) through cellular respiration.
6.
Golgi Apparatus (Golgi Body): This is the stack of flattened, membrane-bound sacs that modifies, sorts, and packages proteins for secretion or delivery to other organelles.
7.
Nucleus: This is the large, central organelle that contains the cell's genetic material (DNA) and controls its activities. It is surrounded by a nuclear envelope.
8.
Endoplasmic Reticulum (ER): This is the network of membranes surrounding the nucleus. The rough ER has ribosomes attached and is involved in protein synthesis, while the smooth ER is involved in lipid synthesis and detoxification.
9.
Vacuole: This is the large, central, membrane-bound sac in the plant cell, used for storage of water, ions, and other substances. Animal cells have smaller vacuoles.
10.
Cytoplasm: This is the gel-like substance that fills the cell and surrounds the organelles. It is where many cellular processes occur.
11.
Chloroplast: This is the green, oval-shaped organelle found only in plant cells. It contains chlorophyll and is the site of photosynthesis, where light energy is converted into chemical energy.
12.
Cytoskeleton: This is the network of protein filaments and tubules that provides structural support, shape, and enables cell movement and transport within the cell.
Parent Tip: Review the logic above to help your child master the concept of comparing plant and animal cells worksheet answers.
