What Are Eukaryotic Cells?

Before diving into the differences, it helps to understand what plant and animal cells have in common. Both are eukaryotic cells, meaning they contain a true, membrane-bound nucleus and specialized organelles. This distinguishes them from prokaryotic cells (like bacteria), which lack a nucleus.

According to the National Human Genome Research Institute, eukaryotic cells are found in all plants, animals, fungi, and protists. The key shared organelles include:

• Nucleus — houses DNA and controls cell activities
• Mitochondria — produce ATP through cellular respiration
• Endoplasmic reticulum (ER) — smooth ER synthesizes lipids; rough ER has ribosomes for protein synthesis
• Golgi apparatus — packages and ships proteins
• Ribosomes — assemble proteins from amino acid chains
• Cell membrane — a phospholipid bilayer that controls what enters and exits the cell
• Cytoplasm — gel-like fluid that fills the cell

With these similarities established, let's examine what makes plant and animal cells different.

Plant Cell vs Animal Cell: Side-by-Side Comparison Table

The table below summarizes every major structural difference at a glance. We will explore each one in detail in the sections that follow.

A labeled side-by-side comparison of a plant cell and an animal cell, highlighting the key structural differences.

Key Differences Explained

1. Cell Wall

The most visible difference under a microscope is the cell wall. Plant cells have a rigid outer layer made of cellulose that provides structural support and protection. This is why plants can grow tall without a skeleton — the cell wall acts as an internal framework.

Animal cells lack a cell wall entirely. They are surrounded only by a flexible cell membrane (also called the plasma membrane), which allows them to change shape — critical for processes like phagocytosis in white blood cells.

Why it matters for students: The cell wall is often the first feature students learn to distinguish. On an unlabeled diagram, look for the thick outer rectangle around the cell — that's the cell wall.

2. Chloroplasts and Photosynthesis

Chloroplasts are double-membrane organelles that contain chlorophyll, the green pigment responsible for capturing light energy. They are the site of photosynthesis, the process that converts CO₂ and water into glucose and oxygen.

Plant cells contain chloroplasts. Animal cells do not. This is the fundamental reason plants are autotrophs (they make their own food) while animals are heterotrophs (they consume food from external sources).

The photosynthesis equation is:

6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ + 6O₂

3. Central Vacuole

Plant cells contain a single, large central vacuole that can occupy up to 90% of the cell's volume. It serves multiple functions:

• Stores water, nutrients, and waste products
• Maintains turgor pressure (keeps the cell rigid)
• Helps the plant stay upright

Animal cells have multiple, smaller vacuoles that primarily handle waste transport and storage, but they never dominate the cell the way a plant's central vacuole does.

Teaching tip: When a plant wilts, it is because the central vacuoles have lost water and can no longer maintain turgor pressure. This is a great real-world connection for students.

4. Centrioles

Centrioles are cylindrical organelles found near the nucleus in animal cells. They play a critical role in cell division (mitosis and meiosis) by organizing the spindle fibers that pull chromosomes apart.

Most plant cells lack centrioles. Instead, they use other microtubule-organizing structures to manage cell division. This is one of the clearest animal-specific features on a cell diagram.

5. Lysosomes

Lysosomes are membrane-bound organelles containing digestive enzymes. They break down waste, old organelles, and foreign material (like bacteria). They are sometimes called the "recycling center" of the cell.

Lysosomes are prominent in animal cells and play essential roles in immune response and cellular housekeeping. While plant cells have similar structures (called lytic vacuoles), true lysosomes as defined in animal cells are generally absent in plants.

6. Cell Shape

Because of the rigid cell wall, plant cells tend to have a fixed, rectangular (or polygonal) shape. Animal cells, with only a flexible membrane, take on round, oval, or irregular shapes depending on their function.

For example, red blood cells are disc-shaped for efficient gas exchange, while neurons are long and branched for signal transmission. Plant cells, regardless of their function, maintain a more uniform rectangular geometry.

7. Cell-to-Cell Communication

Plant and animal cells use different structures to communicate with neighboring cells:

• Plant cells use plasmodesmata — channels that pass through the cell wall, connecting the cytoplasm of adjacent cells
• Animal cells use tight junctions (form seals), gap junctions (allow small molecules to pass), and desmosomes (provide structural anchoring)

How to Teach Plant Cell vs Animal Cell Effectively

For Elementary School (Grades 3-5)

Focus on three big differences: cell wall, chloroplasts, and the large vacuole. Use simple language:

• "Plant cells have a stiff wall; animal cells are squishy."
• "Plant cells have green parts (chloroplasts) that use sunlight to make food."
• "Plant cells have a big water balloon inside (vacuole) that keeps them standing up."

Use our elementary-level comparison diagram for age-appropriate visuals.

For Middle School (Grades 6-8)

Introduce all major organelles and have students create their own comparison tables. Activities that work well:

• Labeling worksheets — give students unlabeled diagrams and have them identify organelles
• Venn diagram activity — students fill in a blank Venn diagram
• 3D cell models — use clay, gelatin, or craft materials to build both cell types

For High School (Grades 9-12)

Go deeper into the molecular mechanisms:

• Why plant cells don't need centrioles (alternative microtubule organizing centers)
• The evolutionary origin of chloroplasts and mitochondria (endosymbiotic theory)
• Detailed comparison of cytokinesis — cell plate vs cleavage furrow
• The role of turgor pressure in plant physiology

Frequently Asked Questions

What are three differences between plant and animal cells?

The three most significant differences are: (1) Plant cells have a cell wall made of cellulose while animal cells do not, (2) Plant cells contain chloroplasts for photosynthesis while animal cells lack them, and (3) Plant cells have a large central vacuole while animal cells have only small, scattered vacuoles.

Do plant cells have mitochondria?

Yes. Plant cells have both chloroplasts and mitochondria. Chloroplasts capture light energy during photosynthesis, while mitochondria break down glucose through cellular respiration to produce ATP. Both organelles are essential for a plant cell's energy needs.

Why don't animal cells have a cell wall?

Animal cells do not need a cell wall because animals have other support structures like bones, cartilage, and muscles. The absence of a rigid cell wall also allows animal cells to change shape, which is necessary for functions like movement, phagocytosis, and forming specialized tissues.

What is the largest organelle in a plant cell?

The central vacuole is the largest organelle in a mature plant cell, often occupying 50-90% of the total cell volume. It stores water, maintains turgor pressure, and contains dissolved nutrients and waste products.

Can you see the difference between plant and animal cells under a microscope?

Yes. Under a light microscope, the most obvious difference is the cell wall — plant cells appear as rigid rectangles arranged in a grid-like pattern, while animal cells look round or irregular with no visible outer wall. In plant cells, you can also often see the large central vacuole and green chloroplasts.

What do plant cells and animal cells have in common?

Both are eukaryotic cells containing a nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, ribosomes, cell membrane, and cytoplasm. They both use DNA as their genetic material and carry out cellular respiration in their mitochondria.

What is the endosymbiotic theory?

The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells. Over time, they developed a symbiotic relationship. This explains why both organelles have their own DNA and double membranes.

How are plant and animal cells similar in terms of energy?

Both types of cells use mitochondria to produce ATP through cellular respiration. The difference is that plant cells can also capture light energy via chloroplasts. So plant cells have two energy pathways (photosynthesis + respiration), while animal cells rely solely on cellular respiration.
