Also called flowering plants Produce flowers Produce fruit
Almost everywhere Artic Tropical jungles Desserts Ocean’s edge
All flowers have the same function Reproductive structure of angiosperms
Sepals and Petals Stamens Pistils Ovary Some flowers do not have all the parts
Protect the developing flower Enclosed in Sepals when flower is a bud Often green in color
Colorful leaf-like structures Shape, size, and number can vary from flower to flower
Most flowers have male and female reproductive parts Stamens are the male reproductive structure Stalk = filament Top = anther Pollen is produced in the anther
Female reproductive structure Found in center of the flower Can have more than one Tip = stigma Tube = style
Found at the bottom of the pistal Protects seeds as they develop Can have more then one ovule
Color, shape, and sent attract animals Insects, birds, bats etc.
Pollination Fertilization Fruit Development Seed Dispersal
Grain of pollen falls on the stigma Nectar (sugar) located deep inside the flower Animals want nectar Brush against the anthers Some pollen can drop on stigma as animal leaves
Pollen falls into stigma and meets the ovule Can fall into same flower or another similar one Sperm meets egg to become a zygote Then develops into the seed embryo
As seed develops, ovary changes into a fruit Can incase one or more seeds Examples: apples, peas, peppers, tomatoes
Fruit is meant to be eaten Animals that eat the fruit will help disperse the seeds
2 types Monocots Dicots
3 or multiple of 3 petals on flowers Long slender leaves, veins run parallel to each other Random bundles of vascular tissue scatter through the stems
4 or 5 petals, or multiples of those, in the flower Wide leaves with branching veins Bundles of vascular tissue arranged in rings
Food Clothing Rubber, kind of Medicines furniture
Flower Structure and Function
Angiosperms Seed plants that produce seeds enclosed in a fruit and are flowering.
Anatomy of a Flower Plant Sex.
Chapter 23 Reproduction in Plants
Angiosperms – vessel seed
Flower Parts Diagram.
REPRODUCTION AND STRUCTURE NOTES
Flowers n Monocots. Flowers n -veins in most are parallel.
FLOWER ORGANS Biology
The Flower What is the function of the flower for the plant?
Warm Up What are the main functions of a plant’s roots, stems and leaves?
Angiosperms EQ: How do I name the types of angiosperms and list the characteristics they share?
PLANT REPRODUCTION. Male Plant Reproductive System Stamen Contains the anther and the filament.
Anthophyte Reproduction In flowering plants, sexual reproduction takes place in the flower A complete flower is made of 4 main organs –Sepals –Petals –Stamens.
1.) Gymnosperms 2.) Angiosperms The flower helps the plant to reproduce.
