A world inside a cell
Meet the smallest unit of life.
SPECIMEN
Preparing your specimen…
Leaf cell: wall, chloroplasts and a large vacuole are visible.
What do a leaf and your cheek have in common?
Both are made of cells. The membrane controls exchange with the surroundings. Cytoplasm is the fluid-rich interior where many reactions occur. The nucleus contains genetic material; mitochondria help release usable energy. A typical leaf cell also has a cellulose wall, chloroplasts for photosynthesis and a large central vacuole. Animal cells have no cell wall or chloroplasts.
Compare the animal and leaf cells. Separate the parts, then select the nucleus and mitochondria. Which structures are shared?
In everyday life
Onion peel cells have cell walls, but most bulb cells do not have chloroplasts: not every plant cell is green.
What this model simplifies
A cutaway, not a microscope image. Colours, organelle counts and relative sizes are illustrative. Real cells are crowded, dynamic and three-dimensional.
A companion to your classroom
Class 6 begins with plants, germination and habitats. Class 7 explores life processes. Class 8 connects microbes, reproduction and conservation. Class 9 looks deeper into cells, tissues, osmosis, classification and division.
