WHat do we learn in botany?
In this class we learn about the classification of plants, every field of study has a vocabulary that helps people talk about what they are doing and what they see.
Botany is the study of plants and how they contribute to the ecosystem, the environment, and the biodiversity of their community.
Taxonomy is how we classify organisms, if we want to buy a packet of seeds it is important to know what to buy or how to look for the seed. Each plant has a species name and the way their name is organized is called taxonomy.
Plants are classified according to whether or not they have seed, the types of root structures, the way they grow and what they produce.
Mosses and ferns grow from spores instead of from seed
Rhizomes and tubers are a form of asexual reproduction
Angiosperms have flowers
Gymnosperms do not have flowers, they have exposed seed instead of fruit
Monocotyledons have parallel veins and petals in groups of three
Dicotyledons have veined leaves and petals in groups of four or five
Vascular plants have xylem and phloem to carry water and sugars
Non-vascular plants are much smaller, no vessels to carry resources.
Some plants are very good at growing and outcompeting everything else, we call these plants invasive.
Kudzu vine is an example of an invasive species.
