Question

part a - animal cell structure drag the labels onto the diagram to identify the structures of an animal cell.

Explanation:

To identify the structures of an animal cell:

• a (outermost layer): Plasma Membrane (regulates entry/exit, flexible boundary of animal cell).
• b (thread - like, near nucleus): Cytoskeleton (provides structural support, involved in movement).
• c (purple, central): Nucleus (contains genetic material, control center).
• d (blue, folded membranes with ribosomes): Rough Endoplasmic Reticulum (RER, synthesizes proteins, has ribosomes on surface).
• e (small dots, throughout cytoplasm): Ribosomes (site of protein synthesis).
• f (stacked, pancake - like): Golgi Apparatus (modifies, sorts, packages proteins/lipids).
• g (small, round, with enzymes): Lysosome (digests waste, foreign substances, not in most plant cells).
• h (bean - shaped, double - membrane): Mitochondrion (produces ATP, energy - powerhouse).
• i (fluid - filled, between organelles): Cytosol (liquid part of cytoplasm, where metabolism occurs).

Answer:

• a: Plasma Membrane
• b: Cytoskeleton
• c: Nucleus
• d: Rough Endoplasmic Reticulum (ER)
• e: Ribosomes
• f: Golgi Apparatus
• g: Lysosome
• h: Mitochondrion
• i: Cytosol
