Cell Structure and Organelles

The network of protein filaments and tubules that helps the cell maintain its shape.

• Cytoskeleton: A structure that provides support and shape to the cell.

• Mitochondria: The powerhouse of the cell that produces energy.

• Nucleus: The control center of the cell that contains genetic material.

• Ribosomes: The site of protein synthesis in the cell.

Organelles that contain digestive enzymes to break down waste materials and cellular debris.

• Mitochondria: The powerhouse of the cell.

• Ribosomes: The site of protein synthesis.

• Lysosomes: Known as the 'clean-up crew' of the cell.

• Endoplasmic Reticulum: The transport system of the cell.

Transports materials throughout the cell. Acts as an assembly line for proteins.

• Mitochondria: The powerhouse of the cell, responsible for energy production.

• Golgi apparatus: Modifies, sorts, and packages proteins for secretion.

• Endoplasmic reticulum: A network of membranes involved in protein and lipid synthesis.

• Lysosomes: Organelles that contain digestive enzymes to break down waste.

The jelly-like substance that fills the interior of the cell and holds organelles in place.

• Cytoplasm

• Nucleus

• Cell membrane

• Mitochondria

The process by which a cell engulfs material from the outside environment.

• Exocytosis: A process of expelling substances from a cell.

• Endocytosis: A mechanism for taking in substances by engulfing them.

• Diffusion: The movement of particles from an area of high concentration to an area of low concentration.

• Osmosis: The movement of water across a semipermeable membrane.

The site of protein synthesis in the cell.

• Nucleus: The control center of the cell that contains DNA.

• Mitochondria: The powerhouse of the cell that produces energy.

• Ribosome: Small structures that read mRNA and assemble amino acids into proteins.

• Golgi apparatus: The organelle that modifies and packages proteins.

The rigid outer layer of a plant cell that provides structure and support.

• Cell membrane: A protective barrier that controls what enters and exits the cell.

• Cytoplasm: The gel-like substance within the cell that holds organelles.

• Cell wall: A protective layer that gives the cell its shape and rigidity.

• Nucleus: The control center of the cell that contains genetic material.

Fluid-filled sacs that store nutrients, waste products, and other materials.

• Vesicles: Small membrane-bound sacs that transport materials.

• Ribosomes: Organelles that synthesize proteins.

• Mitochondria: Organelles that produce energy.

• Vacuoles: Large vesicles that can hold various substances.

A small structure in a cell that is surrounded by a membrane and has a specific function.

• Organelle

• Cytoplasm

• Nucleus

• Cell membrane

Prokaryote ___

• are multicellular: Prokaryotes are made up of multiple cells.

• are unicellular: Prokaryotes are single-celled organisms that lack a nucleus.

• are eukaryotic: Prokaryotes have a defined nucleus.

• are complex organisms: Prokaryotes are more complex than eukaryotes.
