Cell

A eukaryotic cell is a complex cell defined by having its genetic material enclosed within a membrane-bound nucleus and possessing other membrane-bound organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus, forming the basis for all animals, plants, fungi, and protists.

Citoplasmic Membrane

• Controls what enters and leaves the cell
• Like a security gate that controls who can enter and leave the cell.
• Outer border of the cell

Endoplasmic Reticulum

• Transports proteins and materials
• Like conveyor belts that move products around the factory.
• Around nucleus

Ribosomes

• Build proteins
• Like tiny machines that build proteins.
• Floating & on ER

Nucleus

• Stores DNA and controls the cell
• Like the brain or control center of the cell.
• Large circle in center

Nucleolus

• Makes ribosomes
• Like a workshop that builds the tools (ribosomes) needed to make products.
• Inside nucleus

Nuclear Membrane

• Protects the nucleus
• Like the walls of an office that protect important information.
• Around nucleus

Golgi Apparatus

• Packages and ships proteins
• Like a post office that packages and ships materials.
• Near ER

Cytoplasm

• Jelly-like fluid where organelles float
• Like the factory floor where all the work happens.
• Fills the inside

Mitochondrion

• Produces energy (ATP)
• Like a power plant that produces energy for the cell.
• In cytoplasm

Chloroplast

• Photosynthesis (makes food from light)
• Like solar panels that use sunlight to make food.
• In cytoplasm (green)
