|---|---|---|---|---|---|
| Identify the common characteristics of all plants | producers,eukaryotic,multicelled, don't self propell, have cell walls
🗑
|
||||
| producers | make their own food during photosynthesis
🗑
|
||||
| What does photosynthesis require? | chlorophyll
🗑
|
||||
| what is the formula for photosynthesis? | H20 + co2 + sunlight------C6H12O6 + O2
🗑
|
||||
| eukaryotic | have organelles with membranes around them
🗑
|
||||
| vascular plants | have tubelike structures that carry water, nutrients,and other substances throughout the plant
🗑
|
||||
| nonvascular plants | do not have these tubelike structures and use other ways to move water and substances
🗑
|
||||
| plants | need to get, keep and transport water inside themselves
🗑
|
||||
| roots | grow to water, so a plant gets water through these and transports it back to the plant stem
🗑
|
||||
| cuticle | a clear waxy outer layer which keeps water from "osmosing" out of the plant (natures saran wrap)
🗑
|
||||
| pollen | on land plant sperm has a protective coating called this
🗑
|
||||
| How does pollen move to an egg? | by wind or pollinators (bees, birds, bats, beetles)
🗑
|
||||
| How do plants reproduce without water on land? | pollen
🗑
|
||||
| How do plants reproduce in water? | the plant sperm can swim to an egg
🗑
|
||||
| What did plants evolve/develop to have more of in order to help support them on land? | cellulose in their cell walls
🗑
|
||||
| seedless plants | can be non-vascular and vascular
🗑
|
||||
| seed bearing plants | vascular
🗑
|
||||
| bryophyte | seedless land plant that does not have vascular tissue- non-vascular
🗑
|
||||
| what are the common characteristics of bryophytes (seedless, non-vascular plants)? | -lack vascular tissue, -moves material by diffusion or osmosis,-are only a few cells thick, -have no roots,stems or leaves, -have roo-like structures called rhizoids
🗑
|
||||
| rhizoids | threadlike structures that anchor non-vascular plants where they grow
🗑
|
||||
| pioneer species | the first species to live on new land or land disturbed by a natural disaster or man
🗑
|
||||
| name examples of seedless, non-vascular plant | true mosses and liverworts
🗑
|
||||
| name examples of seedless, vascular plants | ferns, horsetails, club and spike moss
🗑
|
||||
| what are common characteristics of seedless, vascular plants? | -reproduces with spores and sperm and egg(sperm requires water to swim), -transports liquids (glucose, water & minerals)by vascular tissue, -have true roots,stems and leaves
🗑
|
||||
| what are the common characteristics of seed bearing plants? | -reproduce seeds, -have roots, stems and leaves, - have vascular tissue
🗑
|
||||
| gymnosperms | vascualr plants that produce seeds that are not protected by fruit
🗑
|
||||
| angiosperms | vascular plants that flower and produce plants with one or more seeds
🗑
|
||||
| What are the 2 groups of seed bearing plants? | gymnosperms and angiosperms
🗑
|
||||
| Angiosperms are divided into what two groups? | monocots and dicots
🗑
|
||||
| What are the common characteristics of monocots ?(mono means one) | They have: -one leaf, -flower parts in threes, - scattered vascular bundles, -veins in leaves are parallel
🗑
|
||||
| What are the common characteristics of dicots? (di means two) | They have: -2 leaves, flower parts in fours (4's) or fives (5's), -vascular bundles in rings, - veins in leaves are net-like
🗑
