Q10a.How wills the absence of any one of the cell organelle affects the cell’s working?
b.Draw a neat diagram of animal cell showing the major functional regions required for
its smooth working.
Answers
Answer:
There are three major functional parts of the cell such as plasma membrane, cytoplasm and nucleus. Plasma membrane regulates the particles entering or leaving the cell. It carries out endocytosis, exocytosis and transport of various substances through different carrier proteins. It is also involved in cell signaling.
Cytoplasm is a gel-like substance present in all cells. All of the cell organelles are suspended in the cytoplasm. Most of the cellular activities as metabolic pathways like glycolysis, key processes like cell division occur in the cytoplasm. Nucleus regulates all the cellular activities by controlling the enzymes required for cellular processes. The four main cellular functions of the cell are protein synthesis, cell division, growth and differentiation are carried out by the nucleus.

Functions of all the organelles are inter-linked to each other and ultimately to the working of the example cell. So, if even a single link is missing, the cell ultimately suffers and die.
Animal Cell Definition. ... They are eukaryotic cells, meaning that they have a true nucleus and specialized structures called organelles that carry out different functions. Animal cells do not have cell walls or chloroplasts, the organelle that carries out photosynthesis.
