Plants are made of organs like stems, roots and leaves. Plant cells work together to make these organs, which can perform the various tasks that a plant needs to carry out to survive and grow
Plant tissues
Epidermal tissue
Palisade mesophyll tissue
Spongy mesophyll tissue
Xylem and phloem
Meristem tissue
Epidermal tissue
Covers the whole plant
Palisade mesophyll tissue
Part of the leaf where most photosynthesis happens
Spongy mesophyll tissue
Contains big air spaces to allow gases to diffuse in and out of cells
Xylem and phloem
Transport water, mineral ions and food around the plant
Meristem tissue
Found at the growing tips of shoots and roots, able to differentiate into lots of different types of plant cell, allowing the plant to grow
Leaves contain ideal structures for photosynthesis
Epidermal cells
Covered with a cuticle which helps to reduce water loss
Palisade cells
Near the top of the leaf where they can get the most light
Vascular bundles
Distribute water and other nutrients to the entire leaf and take away the gas produced by photosynthesis, also help support the leaf structure
Stomata
Little holes that allow CO2 to diffuse directly into the leaf, their opening and closing is controlled by the plant in response to environmental conditions
Plant cell organisation is used by millions of members worldwide
