Card Set Information
Structure, function, etc. of plants.
What are the four characteristics of all plants?
multicellular, autotrophic, cell walls with cellulose, eukaryotic
What did plants evolve from?
Green algae (plant-like protist)
Where does photosynthesis occur in plants?
In chloroplasts in leaves
What is the equation for photosynthesis?
CO2 (carbon dioxide) + H2O (water) + light ----> C6H12O6 (glucose) + O2 (oxygen)
What is the equation for cellular respiration?
C6H12O6 (glucose) + O2 (oxygen) -----> CO2 (carbon dioxide) + H2O (water) + ATP
Do plants undergo cellular respiration, photosynthesis, or both?
Useable energy for all organisms
What is the order that plants evolved? (simplest to complex?)
Mosses, ferns, gymnosperms, angiosperms
What is the only nonvascular plant?
What is a characteristic of nonvascular plant?
They cannot grow tall because they don't have tissues to transport water and nutrients.
What are the 3 groups of vascular plants?
Ferns, Gymnosperms, and angiosperms
Tissue in plants that helps transport water and nutrients throughout the plant
Vascular tissue that transports water
Vascular tissue that transports food or nutrients
Structure that anchors plants and absorbs water and minerals
Structure that supports the plant
What are the 2 groups of seedless plants?
Mosses and ferns
What are the 2 groups of seed plants?
Gymnosperms and angiosperms
What do seedless plants need in order to reproduce?
What is the advantage of seeds?
Provides protection for developing embryo
How is pollination achieved in gymnosperms?
What are the leaves of gymnosperms called?
Where are the seeds located in gymnosperms?
What are the seeds located in for the angiosperms?
What is the male reproductive part of a flower called?
What two parts make up the stamen and what letters represent them in the diagram?
Anther and filament
What is the function of the anther?
What is the female reproductve structure?
What female part of the flower does the pollen first land?
What structure becomes a fruit after the eggs are fertilized?
What structure becomes seeds after they are fertilized?
What structre attracts pollinators?
You find a plant that has parallel veins in the leaves, fibrous roots, vascular bundles scattered, and 6 petals, Is this a monocot or dicot?
You find a plant that has branching veins in the leaves, a taproot, vascular bundles in a ring and 10 petals. Is this a monocot or dicot?
Seed leaf of a plant
Whend oes pollination occur in plants?
When pollen fertilizes the ovules
When a plant slef-pollinates, is this sexual or asexual reproduction?
Sexual reproduction because theire is mixing of pollen and egg.
Pollen from a plant fertilizes the eggs of the same plant.
Pollen from a plant fertilizes the eggs of a different plant.
What are 3 ways seeds are dispersed?
water, wind, animals
What are seeds dispersed by animals often contained in?
What are 2 environmental factors that will cause a seed to come out of dormancy?
Temperature and moisture (rain)
Waxy covering on the top and underside of a leaf
Where does the most photosynthesis occur in a leaf?
Layer inside a leaf that has spaces for gasses to flow?
WHat structure controls the opening and closing of the stoma?
What structure is the opening for gas exchange?
What gas enters the leaf through the stoma?
What gas exits the leaf through the stoma?
If there is too much rain, do the guard cells open or close the stoma?
Open to allow water to exit through the stoma
Plants response to an external stimulus
When a plant moves toward the stimulus
When a plant moves away from a stimulus
Growth of plant towards light
Direction of plant growth in response to gravity
What type of tropism is it when plants roots grown into the soil?
Responsible for timing of seasonal activities by responding to the length of light in a day
What gas speeds up the ripening of fruit?
Monocots and dicots beling to which group of plants?
