a. gymnosperms
b. angiosperms - a. angiosperms
- The part of a branch on which the flower forms
- receptacle
- leaf-like structures that surround and protect the flower before it blooms
- sepals
- the colorful part of a flower that attracts insects and even other small animals
- petals
- The petals of __________ rely on wind or water for pollination
- non-brightly colored flowers
- female reproductive structures
- carpels
- carpels fuse together to form the _____
- pistil
- where the pollen attaches in a flower
- stigma
- long tube that attaches the stigma to the ovary
- style
- eggs
- ovules
- stores the ovules
- ovary
- male reproductive structure
- stamen
- produces pollen
- anther
- supports the anther
- filament
- carried by insects / other animals to the pistil of a flower where it may fertilize the eggs
- pollen
- occurs when the pollen follow the same plan, although they come in many different colors and styles
- sexual reproduction
- when the pollen from an anther fertilizes the eggs on the same flower
- self-fertilization
- when the pollen is transferes to the stigma of an entirely different plant
- cross-pollination
- develops into a fruit
- ovary
- develops into a seed
- ovules
- any structure that encloses and protects a seed
- fruit
- name the 3 parts of a pistil

3.ovules - name the 2 parts of the stamen
-
1.anther
2.filament - make new xylem and phloem
