| Question | Answer |
|---|---|
| What makes a plant a plant? | -Plants are eukaryotic and most are multicellular -plants have tissues -plants have cell walls made of cellulose -most plants are producers -plants have a multi-stage life cycle |
| What are the three major categories of plants? | 1. nonvascular plants 2.seedless vascular plants 3.seed plants |
| What is a brophyte? | nonvascular plant that transports water by diffusion. They are short plants |
| Study Draw a picture and label the brophyte | Study on pg. 2 |
| gametophyte | -lower part of the brophyte -green and leafy. This part is always present |
| sporophyte | -upper part of the bryophyte - consists of stalk and capsule -this part is not always present |
| rhizoids | -root like structures -anchor the plant -absorbs water and minerals |
| stalk | -grows from the leafy part -pat of the sporophyte -only present when producing spores |
| capsule | -grows at the end of stalk -part of the sporophyte -only present when producing spores |
| what is a seedless vascular plant? | similar to a nonvascular plant but it can grow taller and live in drier areas. Water can move through its vascular tissues, Has to have a wet period to reproduce. Examples: ferns, club mosses, and horse tails. |
| What is a seed plant? | Does not rely on water for fertalization(reproduction), they have vascular tissue, lives in both dry and wet areas, reproduces by seeds and spores |
| angiosperms | largest group of plants(seed plants), seeds are fully covered by a protective covering called fruit, example is a peach tree |
| gymnosperms | does not produce flowers, seeds are not fully covered, example is a pine tree |
| What are the plant parts? Describe their function. | roots, stem, leaves, nodes |
| roots | hold a plant securely in the soil and absorbs water and nutrients. |
| stem | produces and supports leaves. They also transport water and nutrients to the leaves and sugars to the roots. |
| leaves | absorb energy from the sun and uses it to make sugars |
| nodes | the points along stems where the new leaves, branches, or flowers are produced. Roots do not have nodes. |
| What are the structures of the leaves? | waxy cuticle, palisade layer, veins, xylem, phloem, spongey layer, stomata, chloroplast |
| waxy cuticle | covers the outer surface of the leaves and helps prevent water loss through evaporation. |
| palisade layer | tightly packed cells that make most of the plants food. the cytoplasm in the palisade layer cells circulates chloroplast so that each get plenty of light. |
| veins | vascular tissue of the leaf. A type of vascular bundle. |
| xylem | vascular tissue that moves water and nutrients into the leaf. |
| phloem | vascular tissue that moves finished sugars out of the leaf. |
| spongey layer | loosely packed cells that allows carbon dioxide, water vapor, and oxygen to move easily to the palisade layer. |
| stomata | opening in the underside of the leaf that allows gases to move into and out of the leaf. The guard cells regulate the size of the openings. |
| chloroplast | contains chlorophyll, gives the plants a green color and this is where photosynthesis takes place. |
| explain how plants stand upright? | look at study guide for answer on pg. 7- explain this on test and write it out in your own words. |
