Describe the Structure and Functions of an Animal Cell. How Is It Different from a Plant Cell?

An animal cell is a eukaryotic cell with membrane-bound organelles but lacks a cell wall and chloroplasts.

Structure and Functions of an Animal Cell

Cell Membrane – Controls the movement of substances.

Nucleus – Stores DNA and controls cell activities.

Mitochondria – Generate ATP through respiration.

Endoplasmic Reticulum (RER & SER) – Synthesizes proteins and lipids.

Golgi Apparatus – Modifies and packages proteins.

Lysosomes – Break down waste and cellular debris.

Differences Between Plant and Animal Cells

Animal cells are specialized for movement and energy consumption, while plant cells focus on photosynthesis and structural support.
