Unit 11 Plant Review Flashcards
Leaf cells
Chloroplast
Guard cells
Stomata
Guard cells
Control size of stomata
Stomata
Allow for exchange of gases
Xylem
In vascular structure; carries water and minerals from roots
Phloem
In vascular structure; carries sugars from leaves
Root hairs
Tiny projections on the surface of the root that increase water absorption
Stigma
Top of female reproductive organ; sticky to trap pollen
Anther
part of male reproductive organ; forms and holds pollen
Petal
Colorful in order to attract pollinators
Sepal
Protects flower bud during development
Ovary
Part of female reproductive organ; holds and protects ovules
Stem
Takes nutrients to flower
Ovule
Contained in ovary; forms seed when fertilized
Filament
Part of make reproductive organ; holds anther up so pollinators will reach the pollen
Pistil
Female reproductive system; stigma style and ovary
Stamen
Male reproductive system; anther and filament
Auxins
Phototropism: lengthen plant cells on shaded side so plant bends toward light
Gibberellin
Produce increase in size of stems and fruit; rapid growth and ends seed dormancy
Cytokinins
Stimulate cytokinesis
Ethylene
Aid in ripening fruit
Adaptation: need for water and minerals
Roots for absorption from soil
Adaptations for conservation of water
Waxy cuticle guard cells and stomata that can close during dry periods/ modified leaves
Adaptation: reproduction
The use of pollen containing the sperm
Adaptation: transport of minerals and nutrients
Vascular tissue with phloem and xylem
Characteristics of plants
Multicellular, autotrophic, photosynthetic, cellulose cell wall, homeostasis, metabolism, eukaryotic, chloroplast, asexual and sexual
Monocot
1 seed cotyledon Fibrous root system Vascular bundles scattered in stem parallel leaf venation Multiples of 3 petals
Dicot
2 seed cotyledons Tap root system Vascular bundles in rings in stem Net leaf venation Multiples of 3 or 4 petals
Angiosperms
Seed covered by ovary and flowers
Gymnosperms
Naked seeds in cones
Fern angiosperm and gymnosperm reproduction
A and g: seeds
Fern: spores
All plants originated from water based algae ancestor
