Chapter 9 - Plants Test Review

What is botany? the study of plants
What are 3 characteristics of plants? eukaryotic cells (membrane bound organelles), multicellular, and producers/autotrophs
Plants are multicellular. What does this mean? cells are specialized to perform specific functions for the plant
Plants are producers. What are producers? use an outside source to make food for themselves
In what ways does a plant cell differ from and animal cell? chloroplasts and a cell wall
What is the function of the cell wall? provides support and protection
What is the function of the chloroplast? converts chemical energy into light energy
What is another name for "producer"? autotroph
What do Xylem cells do? move water and minerals UP from the roots
What do Phloem cells do? move sugars from the leaves DOWN to the rest of the plant
What is cuticle? a waxy protective covering on the outside of the plant which slows down evaporation and keeps the plant from losing water
What is the cell wall made of? cellulose
What are 3 ways that plant seeds are dispersed (move)? wind, animals, and water
From what other group of organisms did plant evolve? algae (plant-like protists)
What are adaptations? inherited traits that increase the chance of surviving and reproducing in a certain environment
How do plants make food for themselves? photosynthesis
What are the function(s) of a plant's roots? absorb nutrients and water, hold the plant in place, stores energy
What are the function(s) of a plant's stem? hold the plant upright, provide a transport area between the roots and leaves
What are the function(s) of a plant's leaves? absorb sunlight to make glucose
What are the function(s) of a plant's flowers? reproduction
Where are the xylem and phloem cells (vascular tissues) made? cambium
What kinds of advantages did living on land provide to plants? plenty of sunlight and carbon dioxide for photosynthesis
What is the function of vascular tissue? transports water and nutrients in some plants
Instead of phylas, members of the plant kingdom are organized into what kind of groups? divisions
What is the scientific name for red oaks? Quercus rubra
How do seedless reproduce? spores
Seedless plants never have what? flowers
What is another name that scientists often call seedless plants? bryophytes
How do nonvascular plants move materials from cell to cell? diffusion and osmosis
What are rhizoids? structures that anchor a nonvascular plant to a surface
What are some examples of nonvascular plants? mosses, liverworts, hornworts
How do vascular plants move materials from cell to cell? tubelike structures (xylem and phloem)
What are some examples of seedless vascular plants? ferns, club mosses, horsetails
About how many seed plant species are there on Earth? 300,000
What are gymnosperms? cone-bearing seed plants
What are angiosperms? flowering seed plants
What kind of tissues do all seed plants contain? vascular
What is the function of the stomata (singular is stoma)? allow carbon dioxide, oxygen, and water vapor to pass through them.
What are some examples of gymnosperms? spruces, pine, redwoods, ginko
What are some examples of angiosperms? tulip, rose, dandelion, grass
What is an annual plants? live one growing season
What are biennial plants? live two growing seasons
What are perennial plants? live for MORE THAN two growing seasons
What is a monocot? seeds have one cotyledon, narrow leaves with parallel veins, flower parts in multiples of 3
What is a dicot? seeds have two cotyledons, leaves have branched veins, flower parts in multiples of 4 or 5
