Monocot vs. dicot stems monocot dicot Vascular tissue forms an outer ring Vascular tissue spread throughout May be a different picture

Stoma Guard cell stoma Functions: Stoma – allows gases into and out of the plant Guard cells – regulate the opening and closing of stoma May be a different picture

Leaf cross section Stoma/guard cells phloem xylem Vascular bundle Functions: Xylem – carries water Phloem – carries nutrients Exact picture

Dicot stem Functions: See previous slide Exact picture

Parts of the flower A = anther B = Filament C = Stigma D = style E = ovary stamen carpel petals sepals Functions: Anther – produces pollen Filament – structural support for the anther Stigma – sticky part where pollen binds to Style – where the pollen tube grows down Ovary – eggs are produced May be different picture

Sponges spicule Functions: Spicule – provide structural support and defense May be different picture

Hydra Functions: Tentacles – capture prey Mouth – where food enters Gastric cavity – where food is digested Stalk – support Attachment disk – where hydra attach to a substrate tentacles mouth Gastric cavity stalk Attachment disk Exact picture

Planaria head eyespots auricle Gastrovascular cavity Functions: Head – detects most sensory information Eyespots – detect light Sensory lobe (auricle) – detects chemicals and touch Gastrovascular cavity – digests food Mouth – where food enters Pharynx – where food is passed from mouth to gastrovascular cavity

Nematoda Functions: Sperm duct – where sperm matures Testis – where sperm is made Anus – where wastes are excreted Intestine - digestion Excretory system – where nitrogenous wastes are excreted Ovary – where eggs are made Uterus – where fertilized eggs mature
