Green Algae Q: What are the characteristics of green algae? A: Green algae are mostly aquatic. They are found in fresh and salt water, and in some moist areas on land.

Life Cycle- Green Algae.

Mosses types of Bryophytes Q: What factor limits the size of bryophytes? A: Bryophytes are small because they lack vascular tissue. Bryophytes: Group of plants that have specialized reproductive organs but lack vascular tissue. Vascular Tissue: specialized tissue in plants that carries water & nutrients.

Life Cycle-Gametophyte & Sporophyte

Vascular Plants-ex:Pteridophytes-Ferns Q: How is vascular tissue important? A: Vascular tissues-xylem & phloem-make it possible for vascular plants to move fluids through their bodies against the force of gravity. Xylem-vascular tissue that carries water upward from roots to every part of a plant. Phloem-vascular tissue that transports solutions of nutrients & carbohydrates produce by photosynthesis through the plant. Tracheids- hollow plant cell in xylem with thick cell walls strengthened by lignin.
