Vocabulary Review Plants
Plant cell with thin walls responsible for metabolic reactions including photosynthesis Parenchyma
Part of the root that contains xylem and phloem Vascular Cylinder/Stele
Type of plant response that orients a plant to light Phototropism
Endodermis Part of the root that ensures water and minerals pass through a cell membrane before they enter the stele
Area of lateral or secondary growth in stems Vascular Cambium
Type of plant cell that provides support during growth Collenchyma
Part of a leaf adapted for maximum absorption of sunlight Blade
What constitutes most of the wood in a tree Secondary Xylem
Process of water uptake and loss by plants Transpiration
What can be used to measure how water flows in a plant Water Potential
Type of flowering plant with netlike veins, a taproot and vascular bundles in a ring Dicot
Areas of active cell division in plants Meristems
Sugar loading in phloem cells involves this Cotransport
Waxy layer in endodermis that keeps water in Casparian Strip
Hormone responsible for phototropism Auxin
Hormone responsible for fruit ripening Ethylene (only hormone that is a gas)
Tissue in plants that moves substances like water and sugar Vascular
Tissue in plants that primarily stores things and supports the plant Ground tissue
Part of angiosperms responsible for reproduction and not found in any other major plant group Flower
Group ancestral to modern plants or group that modern plants evolved from Charophycean green algae
Group of plants in which the gametophyte generation is dominant Bryophytes (mosses)
Group of seedless vascular plants Pteridophytes (ferns )
The power source for transpiration in plants The Sun
Water properties that aid transpiration in plants Adhesion, cohesion
Stomates or Guard cells These control how much water is lost due to transpiration as well as rate of photosynthesis
Three parts of cell signaling Reception, transduction, response
Group of plants that bear seeds but have no flowers Gymnosperms
Connections between plant cells plasmodesmata
Male gametophyte in a flowering plant Pollen grain
The two major groups of plants that use pollination Gymnosperms & Angiosperms
Process in angiosperms that results in a plant embryo + endosperm Double fertilization
Male part of the flower stamen
Female part of the flower Carpel
The ovule in a flower becomes a seed
Triploid tissue in a seed endosperm
Male and female flower parts maturing at different times prevent this Self-pollination
How the sperm reaches the egg in flowering plants Pollen tube
Loss of micronutrients like magnesium can result in this, when not enough chlorophll is made chlorosis
Plants get nitrogen they need primarily through this process Nitrogen fixation by bacteria
Three macronutrients in plants Nitrogen, phosphorus, potassium
Growth in apical meristems is typically referred to as______growth Primary
Two major plant groups whose sperm are flagellated and require water for fertilization Bryophytes & Pteridophytes
Type of plant cell that is typically dead at maturity and very thick-walled sclerenchyma
Sporophyte generation is dominant in these three plant groups Pteridophytes, gymnosperms & angiosperms
