Lecture 1: Introduction Flashcards
What are the defining characteristics of angiosperms?
They have flowers, fruit, are mostly deciduous, and have flat leaves. The ovule is also enclosed (which eventually becomes the fruit with the seeds housed inside).
What are the defining characteristics of gymnosperms?
They are usually evergreens with needle or scale like leaves. They typically do not flower and their seeds are naked and not formed in the fruit. The wind pollinates them.
What is a monocot?
A seed which cannot be separated into any other cotyledons.
What are the defining characteristics of monocots?
The most obvious is the seed not being able to be separated into two parts. They have long narrow leaves with parallel veining, with scattered vascular bundles. Lastly, they typically flower with 3 petals.
What is a dicot?
A seed that can be separated into two cotyledons.
What are the defining characteristics of dicots?
The most obvious being the seed being able to separate into two parts. Like a peanut! Their vascular bundles are in a ring, they have big broad leaves, and they typically flower with 4 or 5 petals.

18C - 27C
What temperature counts are “cold season”?
