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.
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.
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.
They are called "Biomes"
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.
The variety of plant and animal life in a particular habitat. High biodiversity often indicates a healthy ecosystem.
plant and animal fossils are most often found in layers of sedimentary rocks
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.
Spawn
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.

Microscopes
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.
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.
There are six kingdoms recognized by scientists. They are: Animal,Plant,Archaebacteria,Eubacteria, Protista and Fungi.
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.
