Homework Answers
1: Cells
Solution: Cells are the structural and functional units of life and
hence, they are also called the basic units of life.
2. Life
Solution: A single cell exhibits all the life processes that
distinguish living beings from non-living things. Some of these
processes are excretion, digestion, metabolism, reproduction,
growth, etc.
3. Single-celled; multicellular
Smallest organisms are single-celled such as bacteria and archaea.
They have a single cell in their whole body.
Larger organisms have more than one cell in their bodies and are
called multicellular.

A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...
