Plant Growth in addition to Meristematic TissueSeed Plant StructureThe cells of seed plants are organized into tissues in addition to organs.The three main plant organs are roots, stems, in addition to leaves.Roots absorb water in addition to dissolve nutrients in addition to anchor plants in the ground.Stems support the plant body in addition to transport materials throughout the plant.Leaves are the main organs of photosynthesis. They also function in gas exchange.

Dermal tissueVascular tissueGround tissueStemRootLeafRoot, Stem, in addition to Leaf TissuesPlant Tissue SystemsWithin the roots, stems, in addition to leaves are specialized tissue systems. The three main tissue systems:Dermal tissue is like the skin of a plant. It protects the plant in addition to prevents water loss.Vascular tissue consists of xylem (move water throughout the plant) in addition to phloem (moves sugars in addition to other materials throughout the plant).Ground tissue is made up of all of the cells that lie between dermal in addition to vascular tissues. (made up of 3 kinds of cells)Parenchyma cells: function in photosynthesis in addition to storageCollenchyma cells: help support larger plantsSclerenchyma cells: make ground tissue tough in addition to strongPlant Tissue Systems Cont.A fourth kind of tissue, meristematic tissue, is responsible as long as plant growth.Meristematic tissue is the only plant tissue that produces new cells by mitosis.The tips of stems in addition to roots are made of meristematic tissue.
Concept MapincludeincludesincludesincludesincludesincludesPlant TissuesRootsThe two main types of roots are taproots in addition to fibrous roots.Taproots: the primary root grows long in addition to thick, while the secondary roots stay small.Fibrous roots: secondary roots that grow in addition to branch out Roots have two main functionsTo anchor a plant in the groundTo absorb water in addition to dissolved nutrients as long as m the soilTaproots in addition to Fibrous Roots Taproots (Carrots) Fibrous Roots (Grasses)

LeavesThe structure of a leaf is optimized as long as absorbing light in addition to carrying out photosynthesis.To collect sunlight, most leaves have thin, flattened sections called blades.Plants can lose water out of their leaves as they exchange gases with the air (transpiration).To prevent major water loss plants allow air in in addition to out of their waterproof covering only through small openings called stomata.Plants keep their stomata open just enough to allow photosynthesis to take place but not so much that they lose an excessive amount of water. Evaporation of water molecules out of leaves.Pull of water molecules upward from the roots.ABTranspirationBlades On Leaves
