Gymnosperms
Plants that produce seeds
Male and Female cone for reproduction
Angiosperms
Flowering Plants
Flowers contains male and female parts for repoduction
Roots
Absorb water and nutrients from soil
Root hairs
Found on outside of roots to increase surface area to absorb water and nutrients
Dermal Tissue
Surface tissue known as epidermis
To prevent waterloss, nvasion of pests, and for protection
Stems
Transport water & nutrients throughout the plant
Leaves
Captures light for photosynthesis through photoreceptor cells
vascular Tissue
Transport tissue for food and water
Evolutionary function: To grow tall and wide
Roots: Meristematic \n Tissue
Meristem found at the ends of the root
Roots: Ground Tissue
Root cap: protects \n meristem
Xylem
transports water by transpiration
evaporation through plant using cohesion & adhesion
Phloem
Transports food
Stems: Meristematic Tissues
Meristem found at the top of stems
Vascular cambium: growth between xylem & phloem that \n increases thickness
Stems: Ground Tissue
Shoot support in areas of active & inactive growth
Stems: Vascular Tissues
Xylem & phloem
Leaves: Function
Function: capture light for photosynthesis
Leaves: Dermal Tissue (Cuticle)
Fatty waxy coating on surface for protection & to prevent water loss \n
Leaves: Dermal Tissue (Stomata)
Opening on surface & underside of leaf where gas exchange (CO2 & O2) occurs, and water exits
Leaves: Dermal Tissue (Guard cells)
Control opening and closing of the stomata
Leaves during the night
Closed
Leaves during the day
Open
Leaves when it rains
Open
Leaves when its Dry
Closed
Leaves: Ground Tissue (Mesophyll layer)
Mesophyll layer where photosynthesis & gas exchange takes place
Leaves: Vascular Tissue
Xylem & phloem \n found in spongy \n layer
Anther
Filament
Ovary
Petal
Peduncle
Sepal
Stigma
Style
Flowers: Non-reproductive structures (petals)
Attract pollinators for fertilization
Flowers: Non-reproductive structures (Sepal)
Little leaves that protect ovary
Stamen
Male reproductive organs
Anther
Contains pollen
Filament
Holds the anther
Pollen
Contains sperm
Ovary
Protects ovules; develops into fruit \n after fertilization
Ovule
Contains eggs that develop into seed
Pistil (carpel)
Female reproductive organs
Style
Tube pollen travels to reach ovary
Stigma
Sticky structure that catches pollen
Seeds
Embryo, endosperm (food), & seed coat
Monocot
One cotyledon & parallel veins
Corn kernel
Dicot
2 cotyledons & network of veins
Bean
