What is a Plant?
Are plants unicellular or multicellular organisms?
They are multicellular, made up of millions of cells.
Give an example of a plant with seeds
Gymnosperm or angiosperms
What is a gymnosperm?
It is a vascular plant that produces seeds, but doesn't have fruits.
Where does photosynthesis happen?
Photosynthesis happens in the plants' leaves.
Do plants get autotrophic or heterotrophic nutrition?
They get autotrophic nutrition, meaning they can make up their own food.
Are mosses considered plants with seeds or seedless?
Give an example of an angiosperm:
An angiosperm is a plant with fruit, for example a cherry or apple tree.
They absorb sunlight and turn it into chemical energy
Describe photosynthesis:
It is the process where plants use sunlight, water, and carbon dioxide to create their own food (glucose) and release oxygen
What type of vascular system do ferns have?
Ferns have a complex vascular system
Mosses are simple vessels that are missing these parts:
Mosses don't have roots or leaves. They absorb water and nutrients directly from the environment.
It is watery fluid containing sugars.
What does a Eukaryotic plant cell have?
It has a nucleus, cell organism, and cell wall.
What does a complex vascular system mean for plants?
A complex vascular system in plants means they have a network of conducting tissues for transporting water, minerals, and nutrients throughout the plant.
What is the job of a plant stem?
The stem keeps the plant straight and helps transport substances from the roots to the leaves.
What is cell respiration?
Cell respiration is how plants get energy (take in oxygen and realize carbon dioxide).
Describe one of the tissues found in plant cells:
Chlorophyll tissue (photosynthesis)
Supporting tissue (keeps it upright)
Protective tissue (boundary between the plant and environment)
Conductive tissue (transports sap)
Are plants without flowers or seeds more primitive than plants with seeds? Why?
Yes, they are more primitive. Plants without flowers or seeds are considered more primitive because they reproduce through spores and came before seeded plants.
What is the job of plant roots?
Plant roots absorb water, anchor the plant to the ground, and store nutrients.
How do plants release waste substances?
They releasr waste substances like carbon dioxide (CO2), Oxygen (O2), and water.
