Flowers from the outside
open first
Up and in
1. raceme
- long inflorescence with
stalked flowers
2. corymb

flowers
- a spadix is a kind of
spike
- another kind of spike is
the catkin

the inside out
- Down and out
Types of Inflorescence
C. Inflor. That Can Be Either

- all pedicels originated
from the same point
2. Head

originating from the same
point
Types of Fruit
A. Multiple Fruits – formed by the
development of several flowers

Ex: pineapple, mulberry
Types of Fruit

Seed
Develops after an ovule inside the ovary
has been fertilized
 How does fertilization work?

 Pollen
from the anther is carried by wind,
insect, humans, etc.
 Lands on the sticky surface of the stigma
 A pollen tube is formed and grows down the
style
 Pollen tube attaches to the ovule inside the
ovary


Embryo – the baby plant!
Endosperm – food for the baby

Seed coat – protective
covering
Cotyledons – the first leaf or
