Roots
Three functions of roots
Anchor the plant
Food storage
Uptake water
Uptake nutrients
Three functions of stems
Support plant leaves and flower
Allow raw nutrients and synthesized sugars to move throughout the plant
Store food reserves
Green stems synthesize sugars
Three functions of leaves
Synthesize food for the plant
Cool the plant
Allow gas exchange with atmosphere
Store food reserves
Three functions of flowers
Produce seed
Produce pollen
Attract insects
Produce fruit
The edge of a leaf.
Margin
Root structure primarily responsible for the uptake of water and nutrients in a plant root
Root Hairs
The “plumbing” system that conducts water and dissolved mineral up the stems from the roots
Xylem
A leaf composed of two or more leaflets.
Compound Leaf
The male part of the plant
Stamen
(Filament, anther, pollen)
Three types of specialized cells within roots.
Meristem: growth region at the tip of roots
Root cap: cell mass protecting the meristem
Epidermal cells: outer skin of root
Root hairs: responsible for uptake of water and dissolved nutrients
Vascular tissue: xylem and phloem, or the “plumbing” of the plant
Cambium and Cortex: internal root tissues
A root system that is comprised of profusely branched roots with many lateral rootlets.
Fibrous root system
The principle tissue concerned with the translocation of elaborated food produced in the leaves, or other areas, downward in the branches, stem, and roots
Phloem
Difference between opposite and alternate leaf arrangement.
Opposite: Leaflets are directly across from each other
Alternate: Leaflets are staggered across from each other - not directly across.
A flower that is lacking a stamen
Calyx and corolla combined
Perianth
The extreme tip of the root consisting of a group of cells that slough off and are replaced as the tip moves through the soil. It protects the growing region of the root.
Root Cap
Plant tissue capable of cell division and therefore responsible for growth.
Meristem
Meristematic Tissue
The stem of the leaf
Petiole
Sepals and petals are identical
Tepals
Becomes the future fruit and seeds
Ovary & ovules
Diffusion of water through a semi-permeable membrane separating two solutions.
Maintains the level of water necessary in the cell.
Osmosis
This causes herbaceous stems to wilt.
Lack of turgor.
Type of plant with leaves that have parallel veins.
None of the veins on the whole leaf will cross each other. It may look like they fuse together at the top or bottom of the blade.
Monocots
Two benefits of having different inflorescences.
Attracting Pollinators
Maximizing space
Increasing visibility
Promoting cross-pollination
Enhancing seed dispersal
A plant that produces flowers that have either stamens or pistils, but not both on the same plant.
Dioecious
