No. Organisms are all living things like bacteria, plants, and animals. Cells are within all of these organisms. Cells make up all living things.
Cells. Organisms can consist of single-celled organisms like bacteria or multicellular organisms like humans, which are made up of many different types of specialized cells working together to form tissues and organs.
Bacteria multiplies like other living organisms so they can do the jobs they're supposed to.
The cells found in the human body are eukaryotic cells. Organisms that have eukaryotic cells are usually multicellular like humans. Organisms that have prokaryotic cells are usually unicelluar, like bacteria.
Eukaryotes
No, not all multicellular organisms have exactly 2,000 cells. The number of cells in multicellular organisms can vary widely, ranging from a few hundred cells in simple organisms like some sponges to trillions of cells in larger animals like elephants or whales. Each species has a unique cellular structure and complexity, leading to a vast difference in cell count.
Organisms such as bacteria do not contain specialized cells. They are prokaryotic organisms with cells that lack membrane-bound organelles and specialized structures like a nucleus.
Multicellular organisms contain more than one cells to perform important functions. Multicellular organisms like the bacterial colonies and fungi like the mushrooms and, animals and human beings are multicellular organisms that exist only as a group of cells
Eukaryotic organisms can have a wide range of cells, from just a few in unicellular organisms like yeast to trillions in complex multicellular organisms like humans. It varies greatly depending on the species and the organism's complexity.
Living cells that are part of organisms are organized in a specific way to carry out specialized functions, contributing to the overall survival and reproduction of the organism. Cells that are not part of organisms, like single-celled organisms or isolated cells, may function independently and do not contribute to a larger, multicellular organism. Organism cells work together in a coordinated manner to maintain homeostasis, while non-organism cells do not have this higher level of organization.
No, multicellular organisms typically have many more than 2,000 cells. For example, humans have approximately 37 trillion cells, and even smaller multicellular organisms like fruit flies have around 100,000 cells. The number of cells varies widely depending on the species and their complexity.
Flagella are long, whip-like appendages that some cells use for movement. They are typically found in single-celled organisms like bacteria and protozoa, but can also be present in certain cells of multicellular organisms like sperm cells. The waving motion of flagella helps cells swim through liquids.
All living organisms are cells or are composed of cells. Only plant cells have cellulose which makes them stiff and upright. Plants need cellulose because they don't have bones like you and me.
