Plant Morphology Flashcards
What are the vegetative organs of a Plant?
Roots, Leaves, Stems
What is the use of vegetative organs?
Growth and nutrition of plants
Give 3 examples of roots
Taproot, Fribrous, and Adventitous
What is use of roots?
It is for the anchoring and absorption of water and minerals.
It is the entire mass of underground roots produced by a plant.
Root System
It is the main root that goes downward.
Taproot System
It is the root that mainly reaches deep water in the ground
Taproot System
It is smaller lateral roots that is diffused.
Fibrous (Diffuse) System
These plants are excellent from preventing erosion
Fibrous (Diffuse) System
It is roots that develop in uncommon places and has a vegetative reproduction.
Adventitious Roots
It is a type of root that is common in rhizomes of ferns, club mosses and horsetails.
Adventitious Roots
It is the ascending axis for plant support and conduction
Stem
Node of leaves arises
STEM
Enumerate the 4 functions of a STEM?
- Support and Elevation
- Transport Materials between the roots and shoots.
- Nutrient Storage.
- Annual, Lateral, Plant Growth
What are two types of Stem?
Woody stem and Herbaceous Stem
It is a stem the contains thick and tough tissue
Woody Stem
It is a stem that contains soft, green, juicy, tissues. usually last for one year.
Herbaceous Stem
It is usually flat and green.
Leaf
It’s main functions are photosynthesis and transpiration
Leaf
Enumerate all reproductive organs.
Flower, Fruit, Seed
It is the modified shoot that bears the gametes for sexual production.
Flower
It is the ripened ovary.
Fruit
It is the matured ovule.
Seeds
Enumerate the 4 main groups of the Kingdom of Plantae.
- Bryophytes
- Pteridophytes
- Gymnosperms
- Angiosperms
The origin of land plants from ALGAE
Bryophytes
The origin of vascular tissues
Pteridophytes
The origin of the seeds
Gymnosperms
The origin of flowers and fruits
Angiosperms
Enumerate plants that are common in bryophytes.
Hornworts, Liverworts, mosses
Enumerate plants that are common in Pteridophytes.
Lycophytes, Ferns, Horsetail, whiskferns.
Enumerate plants that are common in Gymnosperms.
ginkgoes, cycads, gneteas and
conifers.
Enumerate plants that are common in Angiosperms.
flowering plants, monocots and
eudicots.
A plant with more than 5 meters, woody main trunk
Tree
A plant that is less than 5 meters, it has numerous lateral branches.
Shrub
A plant with little to or no woody tissues at all.
Herb
A plant with climbing or trailing stem maybe a herbaceous or woody species.
Vine
a plant that lives only for one year or completes the vegetative or reproductive cycles in one growing.
season.
Annual
a plant that lives for two years or two growing
seasons.
Binnenial
a plant that lives for several years.
Perrenial
a plant that requires moderate amount of water.
Mesophyte
a plant that needs big amount of water.
Hydrophyte
a plant that lives in watery but salty environment.
Halophyte
a plant that requires small amount of water.
Xerophytes
a plant that is rooted in the ground or soil
Terrestrial
a plant that lives in watery areas.
Aquatic
a plant that is attached on another plant as commensal or parasite.
Aerial or epiphyte
a plant that is usually green due to the presence of chlorophyll.
Autotrophic (Photosynthetic)
a plant that is non -chlorophyllous. It gets its nourishment from other plant by living as a parasite.
Heterotrophic (Non-Photosynthetic)
