Answer 1

Now the same lesson is going on to us

About cell structure and function

Answer:

1. (a) cell
2. (c) Robert Hooke
3. (c) cellulose
4. (a) give colour to the
5. (d) genes

Answer 2

Answer:

Lower levels of organization in multicellular organisms are cells tissues and organs. These are followed by organ system and finally organisms. These levels are absent in unicellular organisms as they have only one cell and therefore no tissue and further levels.

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

Explanation:

Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today's scientific advancements.

Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils.
