Eli Whitney, ?, because it increased what could be produced (with fewer slaves) and allowed the US to export cotton to other countries
Are plants eukaryotic or prokaryotic?
Eukaryotic - has DNA inside the nucleus
also have cell walls, multiple cells
Are plants mobile or immobile?
Immobile - they stay where they are (but of course, grow)
Are plants autotropic or heterotropic?
Autotropic (they make their own food)
How do plants make their own food?
Organelles called chloroplasts that absorb energy from the sun and nutrients from the soil to make its energy.
What is the process of making energy from sun and soil called that plants do?
Photosynthesis
Are plants producers or consumers?
producers
Do plants have tissues and organs?
Yes, both
What is a tissue?
When the same type of cells that have the same job
What is an organ?
When a bunch of tissues work together to do the same thing

What are the characteristics of plants
Eukaryotic Multi-cellular Cell walls Organelles Autotrophs

What are four major types of plants of the 14 phylums?
Mosses - Briophytes
Ferns - Terrophyta phylum
Coniferous - Gymnosperms
Angiosperms (Flowering Plants) - Anthophyta
What is a very significant difference between plants?
Some are vascular and some are non-vascular, but one phylum, briophyta (mosses) don’t have vascules
What are two ways that plants accomplish reproduction?
Seeds and spores
Which of the two groups we studied that use spores to reproduce?
Mosses
Ferns
What is the leafy shoots of a moss
Ryzoids
Do Ferns have vascular tissue?
Yes. The vascular tissue means that you can have lon
What are moss leaves called?
fronds
Where are the spores on ferns?
On the bottom side of the leaf
Where do ferns like to grow?
Usually in warm like tropics, but can even go to
What are the sequoia trees/
Coniferous
Where are the seeds in Angiosperms?
In the flower
Where do mosses live and why?
In moist areas because they don’t have vascular tissues, so every cell has to get their own
