What's This Plant Anatomy Explorer
Learn the main parts of a typical flowering plant and what each one does. Switch between a whole-plant view and a stem cross-section, and test yourself with quiz mode.
Plant diagrams
Simplified, not to scale. The stem cross-section shows xylem, phloem and other tissues in a cartoon style.
Detailed plant diagram A more detailed drawing of a flowering plant with leaves, flowers, fruit, roots and seeds. flower fruit leaf stem roots
Tip: tap or click on different parts of the plant to jump to that organ in the explanation.
Simplified stem cross-section A cartoon cross-section of a plant stem showing epidermis, cortex, phloem, cambium, xylem and pith. epidermis (outer skin) cortex (supporting tissue) phloem (sugars down & around) cambium (new xylem & phloem) xylem (water & minerals up) pith (central storage/support)
This is a simplified cross-section of the stem. Click the disc to jump to the stem explanation.
Quiz mode: test yourself by clicking on the right part
This is a simplified, general guide to flowering plant anatomy for learning and revision. Real plants can differ a lot between species, and specialist diagrams will show more detail (for example different stem types, root systems or reproductive structures).
What's This Plant Mushroom & Fungi Anatomy Explorer
Explore the main parts of a typical gilled mushroom – from the underground mycelium to the cap, gills and spores. This is for learning only, not for mushroom identification or deciding what is safe to eat.
Simplified mushroom diagram
Not to scale. Real fungi come in many shapes and don’t always have all of these features.
Detailed mushroom diagram A more detailed cartoon mushroom with cap, gills, stalk, ring, volva, spores and mycelium in the soil. cap gills ring stalk volva mycelium spores
Tip: tap or click on different parts of the mushroom to jump to them in the explanation. In quiz mode, try to click the correct part.
Quiz mode: test yourself by clicking on the right part
This tool is for education about general mushroom and fungi anatomy only. It is not suitable for identifying wild mushrooms or deciding whether they are safe to touch or eat. Many species are poisonous or deadly. Never eat wild fungi based on apps, diagrams or online tools – always follow expert, in-person guidance and local safety advice.
What's This Plant Tree Anatomy Explorer
See how a tree is put together – from roots and crown to bark, sapwood and heartwood. Switch between a whole-tree view and a trunk cross-section, and test yourself with quiz mode.
Tree diagrams
Simplified, not to scale. Real trees vary by species, age, climate and pruning history.
Detailed tree diagram A more detailed tree with roots below the soil, a trunk, branches and a leafy crown. crown (branches + leaves) branches trunk roots
Tip: click on roots, trunk, branches or crown to jump to that part in the explanation. Quiz mode will ask you to find specific parts.
Simplified tree trunk cross-section A cross-section of a tree trunk showing bark, cambium, sapwood and heartwood. bark (outer protective layer) sapwood (active xylem, water up) cambium (new xylem & phloem) heartwood (older, darker support)
Click on different rings to explore bark, sapwood, cambium and heartwood. In quiz mode you may be asked to find specific tissues.
Quiz mode: test yourself by clicking on the right part
This is a simplified, general guide to tree anatomy for learning and revision. Real trees have more complex structures and vary between species. For tree safety, disease diagnosis or management (for example near buildings or public spaces), always consult a qualified arborist or local expert.
Seed Germination Stages Explorer
Follow a seed as it wakes up, takes in water, sends out a root and grows into a young seedling. Click on different parts to see what they do, and use quiz mode to test yourself.
Germination diagram
Simplified dicot seed (bean-like) in soil. Real seeds and seedlings vary by species and conditions.
Seed germination stages A sequence showing a seed in soil: dry seed, swelling seed, radicle emerging, shoot emerging, and a small seedling with first leaves. seed coat embryo radicle cotyledons first true leaves
Stages: 1 = dry seed, 2 = taking in water, 3 = root appears, 4 = shoot emerges, 5 = small seedling. Click on parts to learn more. In quiz mode, try to click the correct structure.
Quiz mode: test yourself by clicking on the right part
This is a simplified, general guide to seed germination. Real seeds and seedlings vary by species, temperature, moisture and many other factors. For growing advice in your area, follow local guidance and seed packet instructions.
Seed Types & Structures Explorer
Compare a typical dicot seed with a monocot seed. See how seed coat, cotyledons, endosperm and embryo are arranged, and test yourself with quiz mode.
Seed diagrams
Simplified cross-sections, not to scale. Real seeds vary by species.
Dicot seed cross-section Cross-section of a dicot seed showing seed coat, two cotyledons and an embryo. seed coat cotyledons embryo
Dicot seeds usually have two cotyledons that often store food for the embryo.
Monocot seed cross-section Cross-section of a monocot seed showing seed coat, endosperm, a single cotyledon and embryo. seed coat endosperm cotyledon embryo
Monocot seeds usually have one cotyledon and a large endosperm that stores food.
Quiz mode: test yourself by clicking on the right part
This tool is a simplified guide to basic seed structures. Real seeds vary between species, and some have additional or modified tissues. For detailed botany or crop science, use specialist texts or local guidance.
Leaf Anatomy & Function Explorer
Explore external leaf structure and internal tissues responsible for photosynthesis and gas exchange. Switch between surface view and cross-section, tap parts to learn more, or challenge yourself in quiz mode.
Leaf diagrams
Simplified, stylised diagrams. Real leaves vary greatly between species, climate and growing conditions.
Soil Layers & Where Roots Live
Explore a simple soil profile from leaf litter down to subsoil and see where shallow feeder roots and deeper structural roots usually grow.
Soil profile cross-section
Highly simplified, not to scale. Real soils and root systems vary hugely between species, soil types and climate.
surface litter / organic layer topsoil subsoil bedrock / parent material
Tip: click on different soil layers or root zones to see what lives there and what they do.
This is a simplified educational diagram. Real soil profiles vary in thickness, colour and structure, and root systems can be much more complex in different species and environments.
Pollination & Flower Visitors Explorer
Explore the main parts of a flower and how different visitors – bees, butterflies, moths and birds – help move pollen from anthers to stigmas. This is a simplified diagram for learning, not for identifying real plants or insects.
Flower diagrams
Stylised, not to scale. Real flowers and pollinators vary widely between species and habitats.
