Sally's teacher asked her to classify a microscopic organism found in pond water. the first characteristic sally used to figure what kingdom the organism belonged to was
a) cell type.
b) cell diameter.
eliminate
c) number of ribosomes present.
d) chemical composition of cell wall.

The right answer is A) cell type.

The three large types of cells:

* bacterial (procaryote),

* animal (eucaryote).

* plant (eucaryote).

A cell is composed of a cell membrane, a cytosol, and an essential cellular component such as ribosomes, DNA, RNA, various proteins and enzymes ...

Ans. (A). cell type.

All organisms are classified into three kingdoms on the basis of their cell type, which include Monera, Protista, Fungi, Animalia, and Plantae.

Monera includes single-celled, prokaryotic organisms, such as bacteria and archaea. Cells of these organisms lack true nucleus and membrane bound organelles.

Protista include mostly single-celled eukaryotic organisms, such as amoeba and euglena. Eukaryotic cells have true nucleus and other membrane bound organelles.

Fungi includes fungus and other related organisms), such as yeast and mushroom. They have eukaryotic cells, surrounded by cell wall, like plant cells but they lack chloroplasts.

Animalia includes multicellular, eukaryotic organisms such as birds, fishes, insects, and humans. Animals also have cells with membrane bound organelles, but they lack cell wall.

Plantae include all the green plants, such as angiosperms, mosses, and ferns. Cells of these organisms are surrounded by a cell wall and have chloroplasts to perform photosynthesis.

So, the first characteristic that should be used to classify the organisms is to study their cell type. Thus, the correct answer is option (A).

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
