yes
Organism that have one cell (single celled) are so small, you would need a microscope to see them. So, orchids are multicellular.
Bacteria do not need a host organism to live and multiply.
Nutrients and gases can diffuse directly across the cell membrane, thereby eliminating a need for such a complex system. #hopeihelped :)
to help an organism live you need nutrients, like any types of food, depending on the organism.
Yes. An organism is anything that is alive. What constitutes alive? Something that's alive fulfills these 7 requirements: Homeostasis. This means regulating the internal environment. Does Elodea regulate itself? Yes. Organization, or being made up of one or more cells. Elodea is made of cells. Metabolism, or making cells and energy. Does Elodea do this? Yes. Growth. Does Elodea grow? Yes. Adaptation, or being able to change in response to its environment. Can Elodea change in response to its environment? Yes. It will grow towards a source of light. Response to stimuli. Yes, Elodea does respond to stimuli. As mentioned before, it will grow towards light. Reproduction, or producing new organisms. Can Elodea reproduce? Yes. Elodea fulfills all of these conditions; therefore, it is alive and therefore an organism.
You would first need to explain the characteristics of the organism
Living things can have varying numbers of cells. For example, humans have trillions of cells in their bodies, whereas simpler organisms like bacteria may only have a single cell. The number of cells in an organism depends on its size, complexity, and life stage.
A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, in contrast to a multicellular organism that consists of multiple cells.Prokaryotes, most protists, and some kinds of fungi are unicellular.
Because they don't need to. The operative term here is single celled...single celled organisms cannot survive if they specialize at the same level as a cell in a multicellular organism. Now it can breathe but it can't eat
no
Yes, a unicellular organism requires organization to function effectively. Within a single cell, various structures and organelles must be organized to carry out essential processes such as metabolism, reproduction, and response to environmental stimuli. This internal organization enables the cell to maintain homeostasis and perform complex tasks necessary for survival.
it has more cells.
