BIO 2 Flashcards
What do you call the individuals that studies plants?
BOTANIST
There are more than ————- known species of plants and more are to be discovered and named in the years to come.
350 000
What do plants need to sustain growth?
Water
Sunlight
Nutrients from Soil
Carbon Dioxide
is an essential requirement for plants survival.
water
from seed termination to maturity, involves a combination of cellular responses and molecular interaction.
Plant and Growth
All plant species share a common structure:
Stem
Leaves
Roots
The —— distributes water and nutrients from the roots to the leaves, while sugars are transported from the leaves to the remainder of the plant.
Stem
The roots of seed plants have three functions:
-attaching the plant to the soil,
-absorbing water and nutrients and transfering them upwards, and
-storing photosynthetic products.
were modified to exchange gases and absorb moisture.
Roots
are the primary spots for photosynthesis, which is the mechanism by which plants synthesize food.
Leaves
are the primary carriers of water from the roots to the leaves.
Stem
plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support
Xylem
the vascular tissue in charge of transport and distribution of the organic nutrients.
Phloem
are obtained from or created by living organisms and include carbon-hydrogen covalent bonds.
Organic Chemicals
are made up of non - living components and often feature ionic bonds, no carbon-hydrogen bonds, and very few, if any, carbon atoms.
Inorganic Chemicals
chemical compounds for the growth and metabolism of plants
Plant Nutrients
is the chemical change in the body cells that converts food into energy.
Metabolic Processes
include water and minerals.
Inorganic Nutrients
is essential because it acts as a natural solvent in biological processes.
Water
are also vital to bone health, fluid balance management, and chemical transport across cell membranes.
Minerals
Carbohydrates, Proteins, Lipids
Organic Nutrients
are the required building elements of various cell components that certain organisms are unable to generate and must get as preformed.
Organic nutrients
are chemicals produced by plants that govern growth, development,reproduction, longevity, and even death.
Phytohormones (Plant Hormones)
These tiny compounds arise from secondary metabolism and are responsible for plant response to external stimuli.
