Question

i have a doubt in 8th standard syllabus. subject: biology, chapter: microoriganizims.
why are single celled origanizims considred non living.

Answer 1

Living things share common characteristics.
All living things from the microorganisms living in a mangrove swamp to the giant organisms living in the open ocean-share similar as you read about the four
1.Characteristics. Living things are organized, grow, reproduce, and characters all living
things, ante the poemes
respond to the environment of how single-celeder

Organization:
Cells are the basic unit of all living things. Cells, like all living things.
have an inside and an outside. The boundary separating the inside
from the outside of an individual cell is called the cell membrane.
Within some cells, another structure called the nucleus is also surrounded by a membrane
Some types of single-celled organisms contain a nucleus and
some do not. All single-celled organisms contain everything they
need to survive within their one cell. These cells are able to get
energy from complex molecules, to move, and to sense their
environment. The ability to inform these and other functions
is part of their organization.

Growth
Living things increase in size. Organisms inade of one cell do not
grow as large as organisms made of many cells. But all living things
need to get energy. All living things also need to obtain materials to
build new structures inside cells or replace worn-out cell parts. As
result, individual cells grow larger over time.
Reproduction
Living things reproduce, forming other organisms like themselves.
Every organison contains genetic material, which is a code contained in
special molecule called DNA. The code contains characteristics of the
individual organism. In order to reproduce, an organism must make
copy of this material, which is passed on to its offspring
Some single-celled organisms reproduce by a process called
binary fission. In binary fission, material from one cell separates into
two cells. The genetic material of the original cell first doubles so that
cach daughter cell has an exact copy of the DNA of the original cell. You
might say that single celled organisms multiply by dividing. One cell
divides into 2 cells, 2 cells divide into 4, 4 into 8, 16, 32, 64, and so on.
In some cells, binary fission can take place as often as every 20 minutes.

Response
Organisms respond to changes in the environment. Even microscopic
organisms respond to conditions such as light, temperature, and
touch. The ability to respond allows organisms to find food, avoid
being eaten, or perform other tasks necessary to survive.
Hence the basic characteristics for living organisms explaind above are not found In single cell organisms that's why they are considerable as non living organisms
