Answer:
meiosis I
Explanation:
Reduction of the number of sets of chromosomes occurs during meiosis I.
During Meiosis I crossing over of genetic material occurs between chromosome pairs
The cell's series of tunnel-like membranes functioning in transport and storage are the Endoplasmic Reticulum.
What are the functions of the Endoplasmic Reticulum?
In both plant and animal cells, the endoplasmic reticulum is a network of tubules and flattened sacs that perform a number of tasks.
The structure and function of the two ER regions are different. Ribosomes are affixed to the cytoplasmic side of the membrane in rough ER. Ribosomes are not linked to smooth ER. The smooth ER is often a tubular network, whereas the rough ER is a collection of flattened sacs.
Rough Endoplasmic Reticulum (RER)
Endoplasmic Reticulum in rough shape. Membranes and secretory proteins are produced in the rough endoplasmic reticulum. Protein synthesis is carried out by translation on the ribosomes affixed to the rough ER. The rough ER generates antibodies in certain leukocytes (white blood cells). The rough ER creates insulin in pancreatic cells.
Smooth Endoplasmic Reticulum (SER)
The production of carbohydrates and lipids is one of many tasks performed by the smooth ER. Cell membranes must be built using lipids like cholesterol and phospholipids. Vesicles that deliver ER goods to various locations also use Smooth ER as a transitory place.
Hence, the correct answer is the Endoplasmic reticulum.

Since cells have specific functions and capabilities, unicellular organisms have less capabilities and more or less have one job. Functions are reduced with unicellular. Humans, for example who are multicellular, have functions for cell regeneration, clotting, nerves, etc and therefore have a longer list of functions that unicellular organisms like bacteria
Answer:
False - cells can differ in structure in order to perform a specific function..
Explanation:
For example, neurons (nerve cells) are electrically excitable. These have an axon (long section that conducts impulses, and ends which branch out - called dendrite. This is an example of a cell structure unique to a certain function.
The leaves are what usually absorb the sunlight
