|
Epidermal Tissue |
The epidermis is a tissue made up of a single layer of cells that form the outermost layer of a plant. Transparent, light can pass through it and possess fewer green chloroplasts |
|
|
Function of Epidermal Tissue |
Protecting against water loss Regulating gases that are exchanged Water and mineral uptake |
|
|
Palisade Mesophyll |
Immediately below the epidermis of plant leaves. Tightly packed and have more regular shape and more chloroplasts than all other plant cells and lots of photosynthesis |
|
|
Spongy Mesophyll |
Tissue below the palisade mesohpyll Cells are spherical in shape and have many spaces between them Gases enter leaving through tiny pores called stomata, which have guard cells around them (control size of the opening) Maximise gas exchange, |
|
|
Xylem and Phloem |
Water flows up through xylem tissue from the roots to the leaves during transpiration. Phloem cells carry glucose (in the form of sucrose) made in photosynthesis from the leaves of a plant to all other plants during translocation |
|
|
Meristem |
Stem cells are produced and much of the plants growth occurs. They are found in shoot tips reaching for the sunlight and root tips |
