| Question | Answer |
|---|---|
| Angiosperm | flowering plant that produces seeds within a fruit (covered seed) |
| Chlorophyll | green pigment captures light energy for photosynthesis |
| Cuticle | waxy coat on leaves that prevent water loss |
| Cellular Respiration | process by which cells use oxygen to produce energy from food |
| Fertilization | fusing of sperm and egg inside ovule |
| Gymnosperm | vascular seed plant whose seeds are not covered and do not produce flowers nor fruit |
| Germination | early growth stage, "sprouting" of seed |
| Photosynthesis | food making process |
| Stoma | opening in leaf that allows gas exchange |
| Pollination | transfer of pollen from male to female reproductive parts |
| Transpiration | loss of water through stomata in leaves |
| Tropism | movement or growth of a plant toward or away from a stimuls |
| What are the two stage in a plant's life cycle? | sporophyte (produce spores) & gametophyte (produce sex cells) |
| What are the basic characteristics of plants? | autotroph, eukaryote, cell wall, cuticle, muticellular, chlorophyll, reproductive cycles, photosynthesis |
| How are vascular and nonvascular plants different from on another? | Vascular plants have tranport tubes (xylem, phloem, roots, stems & leaves). Nonvasular plants do not. |
| How do seedless nonvascular plants survive on land? | They grow small to the ground, live in damp places, absorb water through their entire surface, & need water to reproduce. |
| How do seedless vascular plants survive on land? | Seedless vascular plants have roots, stems, leaves, cuticles, & need water to reproduce |
| How are gymnosperms different from angiosperms? | Gymnosperms do not have: a covering on their seeds, flowers nor fruit. Angiosperms have all of the above. |
| What do seeds consist of? | young plant, stored food in cotyledon, seed coat* |
| What are the four groups of gymnosperms? | gnetophytes, cycads, conifers, ginkgoes |
| What does the xylem do for vascular plants? | supports plant and moves water and minerals |
| What does the phloem do for vascular plants? | moves food throughout plant |
| What are the two types of roots? | fibrous, taproot |
| What are the functions of roots? | store food, absorb water/minerals, anchor plant |
| What are the two types of stems? | herbaceous, woody |
| What are the functions of stems? | transports materials, supports plant, store materials |
| What are the two types of leaves? | simple, compound |
| What is the function of leaves? | site of photosynthesis and captures sunlight for process |
| What are the reactants of photosynthesis? | carbon dioxide, water, sunlight |
| What are the products of photosynthesis? | glucose sugar, oxygen |
| What are the reactants of cellular respiration? | glucose sugar, oxygen |
| What are the products of cellular respiration? | carbon dioxide, water, ATP (energy) |
| How is cellular respiration different from photosynthesis? | Cellular Respiration: releases energy, produces carbon dioxide & water, site: mitochondria |
| Where does photosythesis take place in the leaf? | Middle of leaf (chloroplast within palisade & spongy layers) |
| What materials move in and out of the leaf through the somata? | carong dioxide, oxygen, water |
| Positive Phototropism | Growth of plant towards light |
| Positive Gravitropism | Growth of plant towards gravity (roots) |
| Negative Gravitropism | Growth of plant away from gravity (stem & leaves) |
| How do seedless plants reproduce? | Seedless plants require water for sex cells to meet |
| How can seeds be dispersed (spread)? | water, wind, animal |
| Identify the 3 methods of asexual reproduction in plants | plantlets, tubers, runners |
