Why do scientist classify living things?

To be able to study all the living things in our universe, we need a way to group or classify them together. Scientists divided all things into living and non-living. Then they divided those (e.g. animal kindom and plant kingdom, then continued dividing them on how the items were seimilar or dissimilar).


What characteristics do scientists use to classify protists?

Protists are difficult to classify, and classification has changed over time. Modern definitions of protists are: "any eukaryote that is not an animal, (land) plant, or (true) fungus" and the second, which describes them mostly by functional or biological terms: "eukaryotes that are never multicellular, that either exist as independent cells, or if they occur in colonies, and do not show differentiation into tissues." Modern classification uses monophyletic groups that are based on ultrastructure, biochemistry, and genetics. visit the Related Link for more information.

Grass is a plant. A "large patch of grass" is a group of plants.


Why Scientist redo their experiment?

In an experiment, there are many variables (things that can't be controlled). For an accurate result, experiments must be done many times over to so that a pattern can be seen, giving scientists an idea of what the result is. For example, if you tested how music affected plant growth, and tested it once, if the plant died because of other causes, it could seem like the music affected the plant. By doing the experiment many times and seeing no affect on the majority of the plants, the scientists would see that music has no affect on plant growth. Scientists redoing experiments is to ensure that the results are credible.


Can Scientists can produce plant food just like a leaf can?

They remove the cell wall, the cells can take up DNA by themselves, or it can be inserted directly into the nucleus.Plant cells can also be transformed without removing the cell wall. DNA that codes for a gene of interest can be inserted within a length of DNA that also has coding for transposon activity. The DNA is then attached to ultra-fine particles of gold, which are "fired" into the plant cells using a pneumatic gun. There are plant enzymes that become activated in response to the mechanical trauma to the cell and some of those enzymes can pick up DNA fragments and insert them into the nucleus. DNA repair enzymes will find the DNA fragments, and because of the transposon components, will insert the entire piece of DNA into the plant genome.Usually this is done to plant tissue cultures. Because this is an inexact process, many plant tissue culture "colonies" will be bombarded with the gold particles "laced" with DNA and scientists will screen the cultures for one or more that had a successful insertion.

Which plant parts do scientists use to classify plants?

Scientists use various plant parts to classify plants, including flowers, seeds, leaves, stems, and roots. These parts help scientists determine the unique characteristics and relationships between different plant species.


Circle the letter of each factor that scientists use to classify the different types of soil into groups a climate B Plant type c soil composition the size of animal pollution?

a) Climate, b) Plant type, c) Soil composition


What factors do scientists use to classify the different types of soil into groups?

Scientists classify soil based on factors such as texture (sand, silt, clay), structure (how soil particles are arranged), pH level, organic matter content, and composition of minerals present. These factors help determine the soil's fertility, drainage, and ability to support plant growth.


Scientists today divide plants into two large groupsd basedv on?

Scientists today divide plants into two large groups based on whether they produce seeds or not. These groups are seed plants (gymnosperms and angiosperms) and non-seed plants (such as ferns, mosses, and liverworts). This classification helps to organize and understand the diversity of plant species.


How do you use the word classify in a sentence?

Botanists could not agree on how to classify the newly-discovered plant. The army decided to classify the project as top secret. Doctors classify a minor scalding as a first-degree burn.


Why do scientists classify plants?

Scientists classify plants to organize and categorize the vast diversity of plant species based on their shared characteristics and evolutionary relationships. This classification system helps scientists study and understand plants more effectively, aiding in areas such as conservation, agriculture, and research.

Why have algae pestered scientists for a long time?

Because scientists and algae dont mix. Also becaust alge doesnt really have a group (animal, plant etc) so they can't classify it, which annoys them.
