Question | Answer |
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 |
