1) What is a human cell?
A human cell is the basic living unit of the body. It’s a tiny bag of fluid with different parts (organelles) that work together to keep the cell alive and do its job.
2) What are organelles?
Organelles are the “mini-organs” inside a cell that each have a specific job (for example, making energy, building proteins, or cleaning up waste).
3) What does the cell membrane do?
The cell membrane is a thin, flexible barrier around the cell. It controls what goes in and out (nutrients, waste, signals) and helps the cell communicate with its surroundings.
4) What is the cytoplasm?
Cytoplasm is the jelly-like fluid inside the cell that holds organelles in place and lets chemical reactions happen. The liquid part is called the cytosol.
5) What is the nucleus and DNA?
The nucleus is a central compartment that stores DNA, the cell’s instruction manual. DNA is organized into genes that tell the cell how to build proteins and control activities. The nucleolus inside the nucleus helps make parts of ribosomes.
6) What are mitochondria?
Mitochondria are the cell’s power plants. They convert food energy into ATP, the form of energy cells use to do work. They also have their own small piece of DNA.
7) What are ribosomes?
Ribosomes are tiny machines that build proteins by reading the instructions from the cell’s RNA. They can float in the cytoplasm or attach to the rough endoplasmic reticulum.
8) What is the endoplasmic reticulum (ER)?
The ER is a network of membranes. Rough ER (with ribosomes) makes and folds proteins for secretion or membranes; smooth ER makes lipids, helps detoxify chemicals, and stores calcium.
9) What does the Golgi apparatus do?
The Golgi is like the cell’s post office: it modifies, sorts, and packages proteins and lipids from the ER and sends them to their final destinations inside or outside the cell.
10) What are lysosomes and peroxisomes?
Lysosomes are bags of digestive enzymes that break down trash, old parts, and pathogens. Peroxisomes break down toxic molecules (like hydrogen peroxide) and long fatty acids.
11) What is the cytoskeleton?
The cytoskeleton is a network of protein fibers (microfilaments, microtubules, intermediate filaments) that gives the cell shape, allows it to move, and helps transport things internally.
12) How do cells grow and divide?
Cells follow a cell cycle to grow and then divide. In mitosis, one cell splits into two genetically identical daughter cells for growth and repair; special cells use meiosis to make sperm or eggs. Cells also have built-in ways to die if they’re damaged (apoptosis).
If you want, I can make flashcards, draw a simple labeled cell, or give real-life analogies for each organelle. Which would help you most?
