Plant Diversity (Ch. 29&31)
what are Charophytes?
These algae are the closet relatives of land plants.
What are gymnosperms?
These plants produce seeds not enclosed in fruit.
What is the apical meristem?
Growth in length of a plant occurs here.
What is the cohesion-tension theory?
This process explains water movement up plants due to cohesion and tension.
What is phototropism?
Growth toward light is called this.
What is the Cuticle?
This adaptation prevents water loss in land plants.
What are angiosperms?
What is the lateral meristem?
Growth in thickness of stems and roots occurs here.
What are the stomata?
Tiny openings on leaves that allow gas exchange.
What is auxin?
This hormone promotes cell elongation.
What is a seed?
This structure protects and nourishes the plant embryo.
What is the anther?
What is the xylem?
This tissue transports water in plants.
What is translocation?
This process moves sugar through the phloem from source to sink.
What is ethylene?
This hormone is responsible for fruit ripening.
What are Bryophytes?
These plants do not have vascular tissue and include mosses.
What is double fertilization?
This involves two sperm cells fertilizing two different cells.
What is the phloem?
This tissue transports sugars in plants.
What is pressure flow?
This pressure drives the flow of sap in phloem.
What is a circadian rhthym?
What is Sporophyte?
This generation is dominant in most plants and produces spores.
What is pollen?
This process allows reproduction without water.
What are dermal, vascular, and ground tissue?
There are the three main tissues systems in plants.
What is passive transport?
This type of transport does not require energy.
What is gravitropism?
This response allows plants to detect gravity.
