- 1Plant Diagram
- 2Monocots vs Dicots vs EudicotsMonocots: fibrous root system, consisting of a mat of thin roots, vascular bundles scattered throughout its tissue, parallel veins
Dicots: taproot system consisting of one thick central root with thin branches, bundles of vascular tissue arranged in a ring, netted veins - 3What is the function of xylem and phloem?-Xylem transports water and solutes from the roots to the leaves
- phloem transports food from the leaves to the rest of the plant - 4Types of RootsTaproot System: found mainly in dicots consists of a large primary root that has smaller branches
Fibrous Root System: found mainly in monocots, consists of many equally sized branch roots - 5Do aquatic plants have thick or thin cuticles?- thin, they dont need a thick cuticle to protect against water loss
- 6Plant Tissues and FunctionsDermal tissue: protective outer covering, protects against water loss
Vascular tissue: supports the plant body and transports water and nutrients (xylem and phloem)
Ground tissue: produces and stores sugars, help support the plant - 7Organelles in Plant CellsPlasma Membrane: controls the movement of substances in and out of the cell, protects the interior of the cell from the outside environment
Vacuole: "storage container", can hold food or even waste
Chloroplast: absorbs sunlight
Cell Wall: structural support and protection
Mitochondria: power house of the cell
Nucleus: brain of the cell
Ribosomes: makes proteins for cell functions
Golgi Apparatus: modifying, sorting and packing proteins
Endoplasmic Reticulum: manufacturing and packaging system - 8Haploid SporesA gametophyte is the haploid multicellular stage in the alternation of generations life cycle of plants and algae. It develops from a spore by mitotic cell division. Spores are the products of meiosis in sporophytes. Gametophytes produce haploid gametes by mitosis.
