Kingdom Plantae What plants need to survive: Plants evolved from algae • They had to evolve structures to acquire, transport, and conserve water when they moved onto land ___________ = 1st land plants – Grow in mats in very moist places – No tubes to conduct water (vascular tissue) – Moisture moves sperm to the egg for fertilization Vascular Tissue Specialized to transport water, minerals, and nutrients – two types • Xylem – transport water and minerals UP from the ROOTS to the other parts of them plant • Phloem – conducts sugars DOWN from the LEAVES and STEMS _________ = 1st vascular plants – Ferns could grow larger than mosses because they had vascular tissue – 1st to develop true roots, stems, and leaves – Developed waxy cuticle to prevent water loss – Reproductive cells called spores – Need water to transport sperm to egg Leaf – structure that carries out most of photosynthesis • Stomata – openings in the cuticle controlled by guard cells that allow gas exchange • __________ = 1st seeded plants Roots - absorbs water and minerals from soil, transports them to stem, anchors plant into ground 1. Tap root—Roots are all same size 2. Fibrous root--One large central root Stem - structural support 1. Herbaceous - flexible, soft, usually green Docsity.com
