Vascular Plants
True or False: Vascular Plants are the most commonly found type of plant in the world?
True
Describe in three words the most common environment that a non-vascular plant can be found in.
Cool, Damp, Shady
Why do plants have flowers?
Flowers are the reproductive organs of a plant.
Give at least two examples of pollinators.
Birds, bees, butterflies, wind, water, small mammals, etc.
True or False: Plants are unable to defend themselves from other creatures.
False.
What do the roots of vascular plants do?
They anchor the plant in place and absorb water out from the soil into the plant.
Give at least two examples of non-vascular plants
Moss, Algae, Liverwort, Lichen, etc.
What is the name of the male-half of a plant?
Stamen
What is the name of the female-half of the plant?
Pistil.
Provide at least two examples of physical defenses in plants.
Thorns, prickles, spines, waxy leaves, trichomes, raphides, etc.
What do the leaves of vascular plants do?
They are the location of the plant where photosynthesis and transpiration occur.
Name three plant parts that non-vascular plants DO NOT possess!.
Roots, Stem, Leaves
What is the purpose of the Stamen?
To make pollen.
What is the purpose of the Pistil?
To grow seeds when fertilized by pollen.
How do chemical defenses like repellents, toxins and digestive enzyme inhibitors work?
They sicken anything that eats the plant.
What is Xylem?
Specialized tissue that transports water from the roots to the leaves of a plant.
How do non-vascular plants obtain water since they do not have roots?
Absorption and Diffusion of moisture into the plant cells.
What is Pollen?
Pollen is the fine, dust like powder that contains the male reproductive cells of seed-bearing plants.
Why do flowers have petals?
To attract pollinators like butterflies and bees.
Name and describe a type of indirect defense plants can use to protect themselves.
1. Mutualistic Relationships- Alliances with Other Organisms
2. Allelopathy- One plant releases chemicals into the surrounding soil to prevent other plants from growing nearby.
What is Phloem?
Specialized tissue that transports sugars from the chloroplast to the cells of the plant.
What are Rhizoids?
Tiny, hair-like structures that anchor non-vascular plants to solid objects.
What is Pollination?
Pollination is the transfer of pollen from the stamen (male) part of the flower to the pistil (female) part of the flower.
What is Fertilization?
The process by which the female reproductive cell (egg) is united with the make reproductive cell (sperm or pollen).
Name and describe one type of unique defense that plants use to protect themselves.
1. Mimicry- Where plants adapt to resemble or imitate another organism.
2. Camouflage- Where plants adapt to blend in with their surroundings.
