What makes plants different from other kingdoms? |
-autotrophic or photosynthesis(take in carbon dioxide and water to make oxygen and glucose) -cell walls, chloroplast, large vacuoles -cuticles |
|
|
Describe nonvascular plants |
three groups of plants (liverworts, hornworts, and mosses) that lack specialized tissues. They have no veins and rely on osmosis to get water. |
|
|
Describe vascular plants |
plants that have specialized tissues. They have veins and reproduce through spores. 3 types of vascular plants are seedless, angiosperms, and gymnosperms. |
|
|
Examples of seedless vascular plants |
fern, club mosses, horsetails |
|
|
Describe angiosperms |
any flowering plants... two types of angiosperms are dicots and monocots |
|
|
Describe gymnosperms |
woody, vascular seed plant whose seed is not enclosed by an ovary. ex: conifers, ginkgoes, cycads, gnetophytes |
|
|
What is the difference between monocots and dicots? |
monocots: parallel veins, 1 cotyledon, 3's petals dicots: branched veins, 2 cotyledon, 4's and 5's petals |
|
|
What is the importance of plants? |
provide us with oxygen and take in carbon dioxide, food (basis of the food chain), paper and wood from conifers (economically important), tea, etc. |
|
|
Describe the plant life cycle |
Sporophyte stage: plants make and release spores Gametophyte stage: the spores of some plants grow and reproduce gametophytes (or sex cells) |
|
|
What is a rhizoid? |
rootlike structure in nonvascular plants that hold the plant in place and helps get the plant water and nutrients |
|
|
What is a rhizome? |
horizontal, underground stem that produces new leaves, shoots, and roots |
|
|
What is pollen? |
plant sperm |
|
|
What is pollination |
transfer of pollen from male to female reproductive systems of seed plants... *pollination is achieved when the pollen gets to the pistil of another plant* |
|
|
What is a cotyledon? |
young plant within a seed |
|
|
What is xylem? |
tissue in vascular plants that conducts water upwards |
|
|
What is phloem? |
tissue that conducts water downwards |
|
|
Describe the two types of root systems |
taproot systems: one main root grows downwards fibrous root systems: several roots spread out from the base of a plant's stem and get water from close to the soil surface |
|
|
What are the two types of stems? |
Herbaceous:flexible Woody:rigid |
