A large, divided leaf, usually found on ferns. Frond
Plants that don’t have vessels to transport materials throughout the plant. Nonvascular Plants
The sex-cell (gamete) producing phase of a plant Gametophyte
Specialized plant tissue that transports water and minerals through the plant. Xylem
A small reproductive cell that can develop into an adult without fusing with another cell. Spore
Metabolic centers that contain the green pigment chlorophyll. Chloroplasts
Plants that have vessels for transporting materials throughout the plant. Vascular Plants
A horizontal underground stem. Rhizome
The separation of a parent plant into parts that develop into whole new plants. Fragmentation
The spore-producing phase of a plant. Sporophyte
Plants that produce seeds in flowers. Angiosperms
Perennials have _______ seasons Many
biennials have ________ seasons two
Annuals have ________ season one
Why does moss need to live near the ground? Moss is a nonvascular plant so it does not have vessels to transport water and minerals up from the ground. It needs to be on the ground to absorb what is needs through osmosis and diffusion.
What do all plants need? Water, air (carbon dioxide), soil, correct temperature, space, and sunlight
What do all plants have in common? The all make their own food through photosynthesis, have cell walls outside their cell membranes and reproduce with a two-part life cycle. (sporophyte and gametophyte)
Describe the three different kinds of roots: A taproot is a large, fleshy, vertical root. Lateral roots branch off the side of a taproot and fibrous roots are a mass of roots that grow horizontally.
Describe the two main types of plant stems: Herbaceous stems are soft, green stems. Woody stems are tough and made out of wood!
