Plant Classification
vonvascular, vascular, seed, gymnosperms, angiosperms
| Question | Answer |
|---|---|
| 2 major categories of plants | nonvascular and vascular |
| Discuss the major difference between nonvascular and vascular plants | the nonvascular do not have vascular tissue and the vascular plants have vascular tissue... ( transport tissue consisting of xylem and phloem) |
| What is the difference between xylem and phloem | xylem transports water up from roots..... PHloem ( FLOW um) transports FOOD from leaves to other areas... Xylem is also a support tissue |
| What are the fancy names for nonvascular plants and vascular plants | bryophytes ( nonvascular.... mosses).... tracheophytes ( vascular plants... think of a trachea ..windpipe) |
| What are examples of nonvascular plants | mosses |
| What are the basic examples of vascular plants | nonseed ( ferns and horsetail) seed ( gymnosperms and angiosperms) |
| What is the basic classification of plants ( domain, kingdom) | domain = eukarya kingdom = plant ( plantae) |
| In mosses, what is the most visible generation in their lifecycle... what you would see on your walk in the forest | the gametophyte generation ( looks like a green carpet)... this is the only type of plant with the gametophyte being obvious |
| Why do mosses live in a moist, damp environment such as a forest ( give 2 reasons) | they need to have water for their fertilization and they don't have transport tissue so they need to live near water since the process of transporting water is done slowly.. |
| Why are mosses short ( approx 1-2 inches)? | they don't have vascular tissue ( xylem and phloem)..so they don't have support to be tall... without vascular tissue if they were too tall they would dry out before the water could reach them by osmosis...which is slow |
| How mosses ( nonvascular plants) .. move their water and other needed materials from cell to cell | movement is by diffusion and osmosis which is a slow process |
| Describe the structure of a moss | The gametophyte is the part that looks like a green carpet and when it grows the sporophyte it grows out of the gametophyte and looks like a green or brown stalk with a little container for the spores) |
| Name two vascular, non seed plants | ferns and horsetails |
| what generation is most visible or obvious in the vascular non seed plants ( ferns and horsetails) | the sporophyte |
| What is the normal habitat for a non seed vascular plant (ferns and horsetails) | damp habitats similar to mosses |
| discuss the size of the non seed vascular plants in the paleozoic era compared to their current size.. What did they form in the paleozoic era that is important for our energy needs | they were very large in the paleozoic era ( they dominated the forests and were tree size)... now they are much smaller ( knee high)... they were responsible for forming much of the fossil fuels we now use |
| What is true about the stems of horsetails and a past use of these plants | they have hollow, ribbed stems, they pull apart in segments... they also have a lot of silica and are scratchy... pioneers used them as scouring pads to scrub pots ( also called scouring rush) |
| What is a major adaptation of seed plants that has allowed them to move to drier habitats | they have pollen that carries the sperm so they can have fertilization without water |
| What is the major difference between gymnosperms and angiosperms | the gymnosperms have naked seeds ( generally on cones) and the angiosperms have seeds in a fruit ( covered seeds) |
| What generation in the plant life cycle is most visible or obvious in a seed plant | the sporophyte ( so a tulip and a pine tree are sporophytes)... the seed has a new sporophyte generation ... the gametophyte is kind of hidden in the sporophyte plant or the pollen) |
| Which type of seed plant does not have flowers or fruits | gymnosperms |
| What type of plants make both spores and seeds | seed plants ( angiosperms and gymnosperms) |
| What type of plants only have spores | nonvascular and vascular non seed |
| Name 3 types of gymnosperms | ginkgo, cycads, conifers |
| which gymnosperm has survived because the chinese grew the seed as a delicacy, it tolerates smog and a female tree has smelly seeds to is not a good one to plant ( plant the male trees) | ginkgo |
| which gymnosperm looks like a palm tree with cones, and you may find them growing in Florida... they were abundant during dinosaur times... | cycad |
| name 4 gymnosperms called conifers | pines, firs, spruce, redwoods... |
| which type of gymnosperm is economically important as lumber and paper, dominate the taiga and higher elevations, drooping branches let them tolerate snow, needle like leaves with waxy coating prevent water loss... and evergreen .photosynthesis year round | conifers |
| When did angiosperms evolve and become dominant | evolved during Mesozoic ( with dinosaurs) and dominant during Cenozoic ( with mammals) |
| What is another name for angiosperms | anthophytes |
| what type of plant is the most widespread at the current time | angiosperms ( they are 75% of the plant kingdom) |
| Where are the seeds in an angiosperm | they are in fruits ( a fruit is a container for seeds)... anything with a seed is a fruit... tomato , cucumbers,peppers, squash) |
| What are the two functions of fruits | to protect the seeds and to help disperse the seeds away from the parents for less competion with parent plants |
| What are the two types of angiosperms | monocots and dicots |
| which type of angiosperm has parallel veins and fibrous roots ( spread out near surface) | monocots |
| which type of angiosperm has netted veins on broad leaves and taproots ( go very deep) | dicots |
| Name 3 monocots | orchids, grasses, corn |
| Name 3 dicots | beans, roses, oak trees |
