Answer:
Meristematic tissue
Explanation:
Meristematic tissue contains actively dividing cells that result in formation of other tissue types (e.g. vascular, dermal or ground tissue). Apical meristematic tissue is found in buds and growing tips of plants.
Fertilization of the egg cell by the sperm usually takes place in the fallopian tube. The fertilized egg then travels to the uterus and implants in the endometrium.
<h3>What are fallopian tubes?</h3>
- Fallopian tubes are also called oviducts or uterine tubes. It is the passage through which the egg enters the uterine cavity from the ovary.
- Fallopian tubes are part of the reproductive tract. They have a smooth muscle wall, an inner mucous membrane, and an outer layer of loose supporting tissue (serosa).
<h3>Why does fertilization take place in the fallopian tubes?</h3>
The fallopian tube (oviduct) regulates fertilization through sperm induction and sperm hyperactivity. Sperm induction is achieved by rheotaxis, thermotaxis, and chemotaxis. Rheotaxis is caused by tubal fluid that creates a current flow from the tubal ampulla to the tubal isthmus.

Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
