Living cells with a diagram.

I'm sorry, but I am unable to provide images or diagrams. However, I can describe the structure of a living cell for you.

A living cell is the basic structural and functional unit of all living organisms. It is enclosed by a cell membrane, which regulates the passage of substances in and out of the cell. Inside the cell, there is a fluid called cytoplasm, which contains various organelles that carry out specific functions.

Some of the key organelles found in a typical animal cell include the nucleus, which contains the cell's genetic material (DNA); mitochondria, which produce energy for the cell; endoplasmic reticulum, which is involved in protein synthesis; Golgi apparatus, which processes and packages proteins; and lysosomes, which break down waste materials.

Plant cells also contain additional organelles such as chloroplasts, which are responsible for photosynthesis, and a large central vacuole, which stores water and nutrients.

Overall, the structure of a living cell is highly complex and organized, with each organelle playing a specific role in maintaining the cell's functions and processes.

Cell Membrane
- Regulates what enters and exits the cell
- Protects the cell from its surroundings

Cytoplasm
- Gel-like substance that fills the cell
- Contains organelles and other structures

Nucleus
- Control center of the cell
- Contains DNA and RNA

Nuclear Envelope
- Surrounds the nucleus
- Protects the DNA

Nucleolus
- Produces ribosomes

Mitochondria
- Produce energy for the cell
- Known as the "powerhouses" of the cell

Golgi Apparatus
- Processes and packages proteins and lipids
- Acts as a sorting and shipping center

Endoplasmic Reticulum (ER)
- Network of membranes
- Transports materials throughout the cell

Rough ER
- Has ribosomes attached
- Produces proteins

Smooth ER
- Does not have ribosomes attached
- Produces lipids and carbohydrates

Ribosomes
- Assemble proteins

Lysosomes
- Contain digestive enzymes
- Break down waste products and cellular debris

Vacuoles
- Store materials
- Can be used for digestion or waste storage

Centrioles
- Help organize microtubules
- Aid in cell division

Cytoskeleton
- Network of fibers that provides structural support and helps with cell movement

Microtubules
- Thick fibers
- Maintain cell shape and transport materials

Intermediate Filaments
- Thinner fibers
- Provide structural support

Microfilaments
- Thin fibers
- Allow cells to move and change shape
