Outer Structures:
* Cell Wall: A rigid outer layer made of cellulose that provides support and protection.
* Plasma Membrane: A thin, flexible layer that controls what enters and leaves the cell.
Internal Structures:
* Cytoplasm: The gel-like substance that fills the cell and contains the organelles.
* Nucleus: Contains the cell's DNA and controls cell activities.
* Nucleolus: A dense region within the nucleus where ribosomes are made.
* Endoplasmic Reticulum (ER): A network of interconnected membranes that helps in protein and lipid synthesis.
* Rough ER: Has ribosomes attached and is involved in protein synthesis.
* Smooth ER: Lacks ribosomes and is involved in lipid synthesis and detoxification.
* Golgi Apparatus: A stack of flattened sacs that processes, packages, and modifies proteins and lipids.
* Mitochondria: The "powerhouses" of the cell, responsible for cellular respiration and energy production.
* Chloroplasts: The sites of photosynthesis, containing chlorophyll, which captures light energy.
* Vacuole: A large, fluid-filled sac that stores water, nutrients, and waste products.
* Ribosomes: Small organelles responsible for protein synthesis.
* Lysosomes: Membranous sacs containing enzymes that break down waste products.
* Peroxisomes: Small organelles that break down fatty acids and produce hydrogen peroxide.
Other Notable Features:
* Plasmodesmata: Channels that connect adjacent plant cells, allowing for communication and transport.
This is not an exhaustive list, but it covers the most important structures found in a typical plant cell.
