Answer: The phrase 'composed of a membrane' best critized the definition
Explanation:
Not all cells are composed of membranes. Prokaryotic cells are found in unicellular organisms, they are with a single chromosome, no nuclear envelope, no membrane-bounded organelles.
Thus, the absence of membrane in the organelles of Prokaryotes like bacteria and cyanobacteria, invalidates and also critized the above definition.
Answer:
It is important that cell growth in a multi-cellular organism be regulated carefully so as to maintain the integrity of the cell cycle
Explanation: Each cell in a multi-cellular organism has it cycle which consist of the inter-phase and the m-phase (active division). Cell growth takes place in the G1 phase of the inter-phase and this ensures that deoxy ribonucleic acid is synthesized in the S-phase in preparation for division.
Hence, adequate cell volume is a key event in order for division to take place. If cell growth is not regulated, it might result in a cell exiting the cell cycle into the resting phase in case of slow growth or result in over-division of a cell in case of over-stimulated growth. The latter is often the case in the development of cancerous cells.

Parthenogenesis is a form of asexual reproduction that results in a viable egg. A good example of this would be the Mexican Whiptail Lizard. The answer would be the last choice, an egg develops without being fertilized.
