ASTERACEAE, ROSACEAE, IRIDACEAE, LAMIACEAE, AMARANTHACEAE



Plant taxonomy is how each plant is categorized into a phylogenetic tree, each species has a domain, kingdom, phylum, class, a family, a genus, and a unique species.

The importance of plants and insects

WHy are plants connected to insects?



When we think about plants it is vital to also think about insects and their relationships with plants.  Some insects eat plants while some eat the insects that eat plants. 


As we learn how the different species coexist we can learn what environment to foster within our garden. 

​Some plants attract pollinators and can strengthen our gardening efforts.

The word etymology derives from the Greek word ἐτυμολογία (etumología), itself from ἔτυμον (étumon), meaning "true sense or sense of a truth", and the suffix -logia, denoting "the study of".

Etymology of the word entomology

Why we need plants


​
Plants are important for the planet and for all living things.
​

Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe.
Living things need plants to live - they eat them and live in them.
Plants help to clean water too.

FLower to Fruit to Seed



Plants that have flowers are called angiosperms

​

​Lets have a flower dissection!


Flower Parts



Petals:
attract pollinating insects such as bees, butterflies, birds and bats to the flowers. Such creatures aid in fertilization


Sepals: 
look like small leaves, they protect the flower before it blooms and help maintain the structure by keeping the flower in place


Peduncle:
The stem that holds the flower up, the stalk, the flower is at the top of the peduncle

Receptacle:
the thicker area at the bottom of the flower that holds its organs
​

Carpel or Pistil:
female part of the plant, located at the center of the bloom, contains the stigma, style and ovary.
​
Ovary: 
located at the base of the flower and has seeds inside known as ovules that turn into fruit.


Picture

https://www.britannica.com/science/pistil


Style: 
the long stalk that supports the stigma.

Stigma: 
located at the tip of the pistil, the part of the flower that's sticky and collects pollen, pollen initiates fertilization so that seeds can be created.

There are many types of stigma:
​

​Stamen:

the male part of a flower, produces male reproductive cells, located on both sides of the pistil. 

Stamen has two parts:

Anther:
the head of the stamen, produces pollen.

Filament:
the stalk attached to the flower that holds the anther.

When pollinating insects, such as bees and butterflies, go to the flower for pollen, they also visit the stigma and fertilize the flower.

Nodes and internodes



Bud is the place for new growth, node is where leaves come out, internode is the stem between the leaves:

​Some plants have aerial roots that come out of their nodes:

Root systems



​Types of root structures

​

Bulbs
look like onions, they have an area for growth at the top and roots growing from the bottom.  Examples of bulb plants: daffodils and tulips.

Corms
look like bulbs but they have growth from the bottom, it is called a basal plate.
Examples include: 
Gladiolus, crocus, and crocosmia

​

Rhizomes
are horizontal underground stems which puts out lateral shoots, new plants grow from the root system. Examples: asparagus, ginger, irises, lily of the valley, cannas, turmeric, and sympodial orchids.

Tubers
have eyes, they are a thickened underground part of a stem or rhizome that can grow at many points, we call those points eyes, the potato is a classic example, there are many flowers that have tubers including the cyclamen, caladium, dahlia, daylily, and peony.
