Lesson 2 Questions
questions and answer
| Question | Answer |
|---|---|
| Tell me the four main group of plants | 1. non-vascular 2. seedless vascular 3. gymnosperms 4. Angiosperms |
| Describe the 3 characteristics of non-vascular plants | 1. low growing 2. have thin cell walls 3. do not have roots for absorbing water from the ground |
| explain how non-vascular plants get nutrients | 1. direct absorption from their surroundings 2. photosynthesis 3. Symbiotic relationship |
| describe where non-vascular plants typically live and their size | on the forest floor, near streams and waterfalls, on rocks and tree trunks, bogs and wetlands. they are less than a few inches tall |
| name the three groups of non-vascular plants | 1. Mosses 2. liverworts 3. Hornworts |
| describe the 2 characteristics of seedless, vascular plants. | 1. vascular tissue 2. they do not produce seeds |
| describe the 2 types of vascular tissue and what they do | 1. phloem- vascular tissue through which food moves 2. Xylem - water and minerals travel through this |
| Name the three groups of seedless vascular plants | 1. ferns 2. club mosses 3. horsetail |
| Describe the 2 characteristics of seed plants | 1. Have vascular tissue 2. use pollen and seeds to reproduce |
| Describe in simple terms how seed plants reproduce | they reproduce through a process called pollination. Pollen from one plant is carried to another plant where it fertilizes an egg that develops into a seed. The seed then is dispersed and germinates and grows into a new plant |
| name the two groups of seed plants | 1. Gymnosperms 2. Angiosperms |
| Give two examples of gymnosperms | 1. Cycads 2. conifers- pine trees |
| describe two ways that angiosperms are different from gymnosperms | 1. Angiosperms are flowering plants their seeds are enclosed within a fruit 2. Gymnosperms do not have flowers or fruit, and their seeds are not protected. they are exposed on the scale's of cones |
| Name the two major groups of angiosperms and give an example of each | 1. Monocots- have only one seed leaf. grasses, lilies 2. Dicots - produce seeds with two seed leaves- roses and violets |
