Plant Anatomy Vegetative and Reproductive Structures
What are vegetative structures (parts) and the Vegetative Stage of a Plant? • Vegetative plant parts of the plant that help it to through its daily processes. • The vegetative stage is when the plant is growing and not ready or getting ready for reproduction.
What are reproductive structures (parts) and the reproductive stage of plants? • The reproductive parts of a plant are the plant structure used for sexual reproduction (making more plants).

Photosynthesis Make food (sugar “glucose”) Store water Reproduce Protect Leaf Function
Modified Leaves • Bulbs • Bracts • Spines
Internal stem anatomy Monocots=grasses, palm trees, corn, ect… Dicots=trees, shrubs, “leafy” ect…
Function of Stems • Transport (food down, water up) • Support (hold up leaves) • Store (food and water) • Protect (thorns) • Reproduction (stolons)
Modified Stems • Thorns • Stolons • Tuber
Root Anatomy • Primary root: The first root to emerge from a seed • Secondary root: Roots that branch off of that root Function • Absorb water • Anchor plant • Store food and water
Flowers • Used for sexual reproduction • They make seeds • Some are male, Some are female and some are both.

Pollination • Pollen (male) lands on female flower and fertilizes egg/ovule (female) and then makes seeds • Pollinators Wind, insects (bees, ants, flies, ect…), bats, birds, butterfly) ect… • Cross pollination: between separate plants • Self pollination: pollinates itself
Types of flowers • Perfect: have stamen and pistol (both sexes, hermaphrodite) • Imperfect: missing a male or female part • Complete: has everything • Incomplete is missing something, anything.
