1) Green substance, or chemical, that captures solar energy. 2) Plants without different types of tissue for carrying water and nutrients. 3) Stage during which plants produce spores. 4) Chemical reaction that produces sugar from CO 2, H 2 0, and light energy. 5) Cells with a nucleus and other organelles. chlorophyll nonvascular sporophyte photosynthesis eukaryotic

6) Earlier, unicellular ancestor of plants. 7) Capable of producing its own food (through photosynthesis). 8) Non-flowering plants that hold their seeds in a cone, rather than in a fruit. 9) Organelle that stores water within a cell. 10) Outer cell layer that allows certain things in or out. green algae autotrophic gymnosperm vacuole cell membrane

11) Rigid structure that surrounds a plant cell. 12) Organelle that contains chlorophyll. 13) Stage during which a plant produces its sex cells, called gametes. 14) An organism consisting of more than one cell. 15) Plants with specialized tissue which transports substances, similar to the way our veins transport blood. cell wall chloroplast gametophyte multicellular vascular

16) Flowering plants that become pollinated before producing seeds and fruit. 17) Waxy outer coating of a leaf, which helps it retain its moisture. 18) Mini-organ that carries out a specific function within a cell. 19) Ability of a membrane to allow certain substances in and out. 20) A woody carbohydrate (sugar) which makes the cell wall. angiosperm cuticle organelle semi-permeable cellulose

1)What is the overall purpose of photosynthesis? 2)How do nonvascular plants transport water? 3)What is one way plants keep from drying out?

Liverwort Hornwort What do all these plants have in common? Mosses

Transportation of nutrients and water via cell-by-cell contact Equilibrium OSMOSIS

So moss just absorbs water through diffusion. But how do other plants get water out to the tips of the branches? Water molecules enter through the roots and travel out through veins of the leaf Then, water diffuses from cell to cell until every cell has the water it needs to carry out… PHOTOSYNTHESIS

Rhizoids  “root-like”

ginger root Plants with rhizomes are hard to get rid of because even when the stems and roots die off, it can still shoot out more roots the next year. Rhizome  Thick, underground stem, which roots grow from. Rhizomes store energy for the next growing season. Fern rhizome
