Scientific Method
These are a series of steps used by scientists to investigate phenomena, answer questions, and acquire new knowledge about the natural world.
What is the scientific method?
Plants that have stems with internal tube-like tissues that transport water, minerals, and sugars to and from leaves and true roots.
What are vascular plants?
This transports water and minerals from the roots and help support the plant.
What is the the xylem?
Before seeds, plants reproduced with this.
What are spores?
leaf-like often very colorful and attract pollinators
what are petals
This variable in an experiment is the one being changed by the scientist.
what is independent variable?
This type of root is a dense network of thin, threadlike roots of roughly equal size that spread out near the soil surface instead of growing a single main root.
what is a fibrous root?
If a leaf has a margin that has jagged teeth like points that point towards the tip of the leaf, it is called this.
What is serrated?
These are 2 divisions of plants that produce seeds.
Options:
Angiosperms, Gymnosperms, or Bryophyta
what are angiosperms and gymnosperms?
psitil that contains ovules, holds seeds and develop into fruits
This is an experimental group.
What are the a set of participants, items, or subjects in a scientific study that are exposed to the treatment/variable?
Plants first evolved from this organism
What is green algae?
Warm temperatures and plenty of rainfall cause these kinds of rings in trees. (describe them)
What are wide rings?
The edge of a leaf is called this.
What is a leaf margin?
leaf-like structure that protects the flower
what are sepals
In an experiment, this group includes the subjects who are kept under “normal” conditions. It is used to collect baseline data for comparing to experimental data.
What is the control group?
These are adjustable pores in the leaves that allow for gas exchange and transpiration to occur.
What are stomata?
This is where angiosperms produce their seeds.
What are flowers?
gymnosperms bear seeds directly on the scales of ________
what are cones
name the 2 parts of the male reproductive parts of a flower
what is the anther and filament
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid: water, apple juice, or milk. What are two examples of constant variables one would expect in this experiment?
What are type of plant, flower pot, soil, amount of sunlight, amount of each liquid?
These are the 2 organ systems found in plants.
What are root and shoot systems?
These are the three types of tissues found in plants.
What are Dermal, Ground, and Vascular Tissue?
This is the removal and storage of carbon dioxide from the atmosphere into the biomass of the tree.
What is carbon sequestering?
name the 3 parts of a female flower
what is the stigma, style and ovary
