🧱 What are Organelles?
Think of cells as cities. Just as cities have specific buildings for specific tasks, cells have organelles for specific jobs. They're like tiny workers doing their tasks to keep the cell running smoothly.
🚀 Organelle Specialization
The cool thing about organelles? They're specialists, not generalists. This means they're really good at their job, like how a chef excels in the kitchen but might not be the best plumber.
Real-world example: If cells were a big factory, the organelles would be the specialized machines each responsible for one type of product.
🛠 Organelle Structures
Some organelles are surrounded by a single or double layer of membrane, like a jacket. Others are solid, mostly made of proteins or RNA and don't have this jacket.
Famous organelles? Nuclei, vesicles, ribosomes, and the plasma membrane.
🏰 What Aren’t Organelles?
🐾 Eukaryotic vs. Prokaryotic Cells
Eukaryotic cells = cities with many buildings (organelles). Prokaryotic cells = small villages with fewer buildings. This might be because their village size is small, or they like keeping things simple and quick.
🤔 Are the following part of the bustling city streets (cytoplasm) or separate entities?
a. Vacuoles in plant cells
b. Mitochondria and chloroplasts
Remember: One way to define cytoplasm is everything inside the city walls (plasma membrane) but outside the city hall (nucleus). Another definition? The busy streets themselves where all the buildings (organelles) stand.
🌱 Plant Cell Division Queries
During cell division, mitosis divides the city hall (nucleus), and cytokinesis divides the entire city. But, what happens to the energy factories (mitochondria) and solar panels (chloroplasts)? And what about the water storage tanks (plant vacuoles)?
