Cell
The structural and functional unit of life.
What is the cell membrane?
The cell membrane is a flexible barrier that surrounds the cell, controlling the movement of substances in and out.
What is the nucleus?
The nucleus is the membrane-bound organelle that contains the cell's genetic material (DNA) and controls cellular activities.
What are ribosomes?
Ribosomes are small structures where protein synthesis occurs.
What is the cytoplasm?
Cytoplasm is the jelly-like substance within the cell membrane that holds organelles and is the site of many metabolic processes.
What are mitochondria?
Mitochondria are the powerhouse of the cell, responsible for generating energy through cellular respiration.
What is the function of the endoplasmic reticulum (ER)?
The ER is involved in protein and lipid synthesis; it can be rough (with ribosomes) or smooth (without ribosomes).
What are lysosomes?
Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.
What is the Golgi apparatus?
The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
What is a chloroplast?
Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting sunlight into energy.
What are the main structures found in a plant cell?
Main structures in a plant cell include the cell wall, cell membrane, chloroplasts, vacuoles, nucleus, and mitochondria.
