Classifying sorting them in groups by size, shape, color, how they reproduce or produce offspring
Nonvascular: have no vessels, no roots, no stems or leaves. Examples: Mosses & Liverworts
Vascular: have vessels to transport food and water. They have roots, stems and leaves. Example: Grass, corn, trees, flowers, bushes
Xylem: transports water
Phloem: transports food & nutrients
Gymnosperms A plant that produces seeds that are exposed rather than seeds enclosed in fruits
one monocots have ____ cotyledon
parallel Monocots have _________ veins on leaves
monocots have 3 part symmetry for flowers
symmetry the quality of being made up of exactly similar parts facing each other or around an axis.
fibrous part of a root system in which roots branch to such an extent that no single root grows larger than the rest
Dicots Flowering plant whose embryos have 2 cotyledons.
Angiosperms flowering plants that produce seeds in fruit .
taproots deep roots that have tiny hairs to absorb water and nutrients
Roots Absorbs water and minerals from the ground. Anchors plant in ground.
TRANSPIRATION Evaporation of water from the leaves of a plant
Stems Carry substances between roots and leaves; provide support for plant; holds leaves up to sunlight
xylem vascular tissue that carries water upward from the roots to every part of a plant
phloem the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
herbaceous non woody
woody hard and rigid
Photosynthesis 6CO2 + 6H2O + light
leaves Photosynthetic organ of the plant, used to convert sunlight into food
Stomata pores within the leaf that open to let CO2 in and O2 out. Guard cells open and close.
Cuticle waxy covering on leaf that prevents water loss
Flower The reproductive structure of an angiosperm
Stamen The male part of the flower
PISTIL The female part of the flower
Reproduction The means in which a plant makes new plants, typically via flower or cones and seeds.
Pollen is produced by the stamen. A fine dust that contains the sperm of seed
Asexual Sometimes called vegetative reproduction. These types of plants are able to reproduce through structures such as rhizomes, tubers, corms, plant
Germination occurs when a seed sprouts (usually caused by changes of temperature and moisture)
Perennials live several years, and reproduce many times, woody plants are perennials
Annuals a plant that completes its life cycle in one growing season (grows, flowers, reproduces and then dies)
Biennials takes two growing seasons to complete, it reproduces in the second growing season
MERISTEMS Plants grow only at their tips in regions called
PRIMARY GROWTH makes a plant taller at roots and stems
SECONDARY GROWTH makes a plant wider, or adds woody tissue
Rings tree ______ tell the age of a tree, each ring represents a growing season. The photo shows a tree who has been through four growing seasons. The lighter thinner rings are winter periods.
VASCULAR ________ cambium area of the tree that makes more xylem and phloem and forms the annual rings
