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.
What is the difference between the animal cell and plant cell?
One main difference is that plant cells have a cell wall made of cellulose, while animal cells do not. Plant cells also typically have chloroplasts for photosynthesis, which animal cells lack. Plant cells often have a large central vacuole, while animal cells have smaller, scattered vacuoles.
How do scientists group organisms?
Firstly scientists classified organisms into 2 kingdoms:animal kingdom and plant kingdom.Then when science became advanced organisms where classified into 5 kingdoms:plant kingdom,animal kingdom,monera,protista,fungi.
A large region of earth with particular plant and animal communities is called?
They are called "Biomes"
An animal that eats plant?
A herbivore is an animal that primarily eats plants. Herbivores have evolved digestive systems that allow them to extract nutrients from plant-based foods. Examples of herbivores include cows, rabbits, and deer.
Biodiversity?
The variety of plant and animal life in a particular habitat. High biodiversity often indicates a healthy ecosystem.
How are sedimentary rock layers used be scientists to learn about the past?
plant and animal fossils are most often found in layers of sedimentary rocks
What mean endangered?
If an animal or plant is endangered, it means that threats to its survival are considerable, and that action must be taken to ensure its continued existence. This action often takes place in particular forms of greater protection for the animal or plant's habitat.
What is the reproduced young of a particular person animal or plant?
Spawn
What is genetic manipulation?
genetic manipulation is the basics of plant and animal breeding. It is a process of introducing a particular gene into the seed so as to bring in the particular quality in the plant.
What kingdom did scientists add for organisms that may have both plants and animal charactistics?
Scientists added the kingdom "Protista" to classify organisms that exhibit both plant and animal characteristics. This kingdom includes a diverse range of eukaryotic microorganisms, such as algae (which have plant-like traits) and protozoa (which share animal-like traits). Protists play a crucial role in various ecosystems, often serving as primary producers or as part of the food web.
What percentage of plant and animal groups do scientists think became extinct at the end of the Mesozoic Era?
50%
What technological design allowed scientists to determine differences in the internal structures of plant and animal cells?
Microscopes
Is organelles in plant cells or animal cells?
Organelles are found in both plant and animal cells. They are the "little organs" within cells that allow the cell to carry out particular functions.
How the age of plant and animal fossils is determined?
The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.
How many kingdoms in terms of classification of living things have scientists identified?
There are six kingdoms recognized by scientists. They are: Animal,Plant,Archaebacteria,Eubacteria, Protista and Fungi.
What are some differences between animal and plant cells for fourth grade?
Animal cells have centrioles, which plant cells lack. Plant cells have a cell wall and chloroplasts for photosynthesis, while animal cells do not. Animal cells usually have a round or irregular shape, whereas plant cells often have a rectangular shape.
