Types of Cells | Don't Memorise

TL;DR

Plant cells have a cell wall, chloroplasts, and a large central vacuole; animal cells lack a cell wall, chloroplasts, and have numerous small vacuoles. Additionally, cells are classified into prokaryotic (primitive nucleus) and eukaryotic (true nucleus) cells.

Transcript

Here are two cells on your screen. Can you tell me which one is a plant cell and which is an animal cell by merely glancing at them ? Don’t worry ! It’s not that difficult ! Plant and animal cells can be distinguished from each other by merely looking at them. The presence and absence of a few characters are enough to let us know the differences. L... Read More

Key Insights

• ⬛ Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells lack a cell wall, chloroplasts, and have numerous small vacuoles.
• 🌱 Both plant and animal cells are examples of eukaryotic cells.
• 🖤 Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have a true nucleus and well-defined membranes.
• ❓ Cells are broadly classified into prokaryotic and eukaryotic cells.

Questions & Answers

Q: What is the main difference between plant and animal cells?

The presence of a cell wall, chloroplasts, and a large central vacuole in plant cells, while animal cells lack a cell wall, chloroplasts, and have numerous small vacuoles.

Q: How are cells classified?

Cells are classified into prokaryotic (lack nucleus and membrane-bound organelles) and eukaryotic (have a true nucleus and well-defined membranes for organelles) cells.

Q: Can animal cells be considered eukaryotic cells?

Yes, animal cells are considered eukaryotic cells because they have a true nucleus and well-defined membranes for organelles.

Q: What are the main characteristics of prokaryotic cells?

Prokaryotic cells lack a proper, well-defined nucleus and membrane-bound organelles. They have a nucleoid for genetic material and organelles without well-defined membranes.

Summary & Key Takeaways

• Plant and animal cells can be distinguished by the presence of a cell wall, chloroplasts (in plant cells), and the size and location of vacuoles.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a true nucleus and well-defined membranes for organelles.

• Cells are broadly classified into prokaryotic and eukaryotic cells.
