Answer:

C. gametes

Explanation:

The alternation of generations is a process of reproductive cycles that occur in plants, algae and cnidarians. The main characteristic of this type of reproduction is that it happens in two different generations alternating in a single life cycle of the organisms.

For this process to occur in plants, it is necessary that there is a generation that produces spores (sporophytic generation) and a generation that produces gametes (gametophytic generation). The generation that produces spores should produce diploid cells, while the generation that produces gametes must produce haploid cells.

When haploid cells arise from the germination of spores (which are haploid), the phase called gametophytic begins in the body, where the formation of two gametes (one male and one female) occurs. These gametes will merge during fertilization, generating a diploid embryo, which will undergo several mitoses until it becomes an adult that is capable of forming spores.

Glia that provide myelin for neurons in the brain are called ________.
kati45 [8]

Answer:

oligodendrocytes

Explanation:

Glial cells are part of the nervous system. These are helper cells that support the function of the central nervous system (CNS) and can be called oligodendrocytes when they supply myelin to neurons.  These cells are responsible for producing the myelin sheath have the function of electrical insulator for CNS neurons. They have extensions that wrap around the axons, producing the myelin sheath.

It is estimated that there are 10 glia cells in the CNS for each neuron, but because of their small size, they occupy half the volume of nervous tissue. They differ in form and function and they are: oligodendrocytes, astrocytes, Schwann cells, ependymal cells, and microglia.
