Answer:
A)All organisms are composed of one or more cells.
B)All cells have membrane-bound structures that have certain functions.
D)The cell is the basic unit of organization on organisms.
Explanation:
Created by Mathias Scheiden and Theodor Schwann, Cell Theory involves the assertion that all living beings are formed by cells and that these cells have functional structures, which was possible as a result of the development of microscopy, being, today, a of the most important generalizations in the field of Biology.
In addition, according to cell theory, the cell is the smallest unit of life, and new cells are formed from the division of cells that already exist, and this process occurs from cell division. Another important pillar of this theory is the fact that the cell is the unit of reproduction and transmission of inherited characteristics, that is, all genetic characters transmitted from parents to children, are transmitted from one cell to another in the process of reproduction.
In summary, cell theory states that:
- All organisms are composed of one or more cells.
- All cells have membrane-bound structures that have certain functions.
- The cell is the basic unit of organization on organisms.
Answer: Option E
Explanation:
Mutation can be defined as the change in the sequence of DNA, either due to mistakes that takes place during replication or because of environmental factors.
The cause of mutation can be chemical mutagens, UV exposure, spontaneous mutation during replication, introduction of analog base pair.
Mutation can be positive or negative, but most of the time its effect is negative.
Hence, the correct answer is option E

Answer:
Plants are divided into two major groups i. e. Cryptogams and phenarogams. Cryptogams is divided into three groups i. e. thalophta, bryophyta and Pteredophyta. Thalophta is again divided into algae and fungi, while phenarogam is divided into two groups i. e. Gymnosperms and Angiosperms. Angiosperm is again divided into two groups i. e. Monocot and dicot.
