Botany Terms Flashcards
Anther
Pollen sac male flower
Apex
Tip of root or shoot
Apical dominance
Tendency of an apical bud to produce hormones that suppress the growth of buds below the stem
Axil
Location where leaf joins stem
Camblum
Layer of growing tissue that separates the xylem and holes and continuously produces new xylem and phem cells
chlorophyll
Green pigment in leaves that is responsible for trapping light energy from the sun
Chloroplast
A specialized component of certain cells; contains chlorophyll and is responsible for photo synthesis
Cortex
Cells that make up the primary tissue of the root and stem
cotyledon
First leaf that appears on a seedling . Seed leaf
Cuticle
Impermeable surface layer on epidermis of leaves and fruit
dicot
Having two leaves
Epidermis
Outermost layer of plant cells
Guard cells
Epidermal cells that open and close to let in water, oxygen, and carbon dioxide pass through the stoma
Internode
Space between nodes on a stem
Meristem
Specialized groups of cells that are a plants growing points
Mesophyll
A leaf’s inner tissue, located between the upper and lower epidermis contains the chloroplasts and other specialized cellular parts organelles
Monitor
One seed leaf
Node
An area on a stem where a leaf, stem, or flower bud is located.
Ovary
Part of a female flower where eggs are located.
Petiole
Stalk that attaches leaf to stem
Pholem
Photosynthate- conducting tissue
Photosynthate
A food product sugar or starch created through photosynthestis
Photosynthesis
Process in green plants converting carbon dioxide and water into foods sugar and starch using energy from sunlight
Pistil
Female flower part consists of stigma style and ovary
Respiration
Process of converting sugar and starch to energy
Stamen
Male flower part consists of anther and supporting filament
Stigma
Top of female flower part that collects pollen
Stoma
Tiny openings in the epidermis that allow water, oxygen, and carbon dioxide to pass in and out of the plant
Style
Part of female flower that connects the stigma to the ovary. Pollen travels down the style to reach the ovary where fertilization occurs.
Transpiration
Process of losing water in form of vapor through the stomata.
Turgor
Cellular water pressure responsible for keeping cells firm
Vascular tissue
Water, nutrient, and Photosynthate conductive tissue ( xylem and pholem)
Xylem
Water and nutrient conducting tissue
