Wakefield HS Plants

multicellular, autotrophic, cell walls with cellulose and eukaryotic
What are the 4 characteristics of all plants?
Green algae (plant-like protist)
What did plants evolve from?
In chloroplasts of leaves
Where does photosynthesis occur in plants?
CO2 (carbon dioxide) + H2O (water) + light yields C6H12O6 (glucose) + O2 (oxygen)
What is the equation for photosynthesis?
C6H12O6 (glucose) + O2 (oxygen) yields CO2 (carbon dioxide) + H2O (water) + ATP
What is the equation for cellular respiration?
Do plants undergo cellular respiration, photosynthesis or both?
Useable energy for all organisms
Mosses, Ferns, Gymnosperms, Angiosperms
What is the order that plants evolved (simplest to complex)?
What is the only nonvascular plant?
They cannot grow tall because they don't have tissues to transport water and nutrients.
What is a characteristic of nonvascular plants?
Ferns, Gymnosperms and Angiosperms
What are the 3 groups of vascular plants?
Vascular tissue
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
Mosses and ferns
What are the 2 groups of seedless plants?
Gymnosperms and angiosperms
What are the 2 groups of seed plants?
What do seedless plants need in order to reproduce?
Provides protection for developing embryo
What is the advantage of seeds?
Cone-bearing plants
How is pollination achieved in gymnosperms?
Flowering plants
What are the leaves of gymnosperms called?
Where are the seeds located in gymnosperms?
What are the seeds located in for angiosperms?
Stamen - A
What is the male reproductive part of a flower called and what letter represents it in the diagram?
Anther - B and filament - C
What 2 parts make up the stamen and what letters represent them in the diagram?
Produces pollen
What is the function of the anther?
Pistil - H
What is the female reproductive structure and what letter represents it in the diagram?
Stigma - D
What female part of the flower does the pollen first land and what letter represents this part in the diagram?
Ovary - F
What structure becomes a fruit after the eggs are fertilized?
Ovules (eggs) - G
What structure becomes seeds after they are fertilized?
Petals - I
What structure 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 bundes in a ring and 10 petals. Is this a monocot or dicot?
Seed leaf of a plant
when pollen fertilizes the ovules
When does pollination occur in plants?
Sexual reproduction because there is mixing of pollen and egg.
When a plant self-pollinates, is this sexual or asexual reproduction?
Self pollination
Pollen from a plant fertilizes the eggs of the same plant
Cross pollination
Pollen from a plant fertlizes the eggs of a different plant
Water, wind, animals
What are 3 ways seeds are dispersed?
What are seeds dispersed by animals often contained in?
Temperature and moisture (rain)
What are 2 environmental factors that will cause a seed to come out of dormancy?
Cuticle - A
Waxy covering on the top and underside of a leaf
What is structure B?
Palisades mesophyll - C
Where does the most photosynthesis occur in a leaf?
Spongy mesophyll - G
Layer inside a leaf that has spaces for gasses to flow?
Vascular bundle (xylem & phloem)
What is structure D?
Guard Cells - F
Which structure controls the opening and closing of the stoma?
Stoma - E
What structure is the opening for gas exhange?
Carbon dioxide
What gas enters the leaf through the stoma?
What gas exits the leaf through the stoma?
Open to allow water to exit through the stoma
If there is too much rain, do the guard cells open or close the stoma?
Plants response to an external stimulus
positive tropism
When a plant moves towards the stimulus
negative tropism
When a plant moves away from a stimulus
Growth of plant towards light
direction of plant growth in response to gravity
Positive gravitropism
What type of tropism is it when plants roots grown into the soil?
responsible for timing of seasonal activities such flowering by responding to the length of light in a day
What gas speeds up the ripening of fruit?
Monocots and dicots belong to which group of plants?
