Answer:

True

Explanation:

Bacteria are prokaryotic organisms. Being prokaryotes, bacteria do not have a nucleus in their cells. Their DNA or the genetic material lies in the cytoplasm itself. Therefore, if the observed cells have a nucleus and other membrane-bound organelles, this means that those cells were not the bacterial cells. Bacterial cells also do not have other membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.

In this case, it is given that <em>Mycoplasma pneumoniae </em>lacks cell wall. some antibiotics such as penicillin works by interfering the synthesis of the cell walls. As these microbes do not have cell wall, the penicillin like antibiotics would not work.

In this case, the antibiotics, which interferes with the DNA (deoxyribonucleic acid) formation and replication can work.

Angiosperms do not need water for fertilization. Why? (3 points) Group of answer choices Flagellated sperm travel to the ovary i
astraxan [27]

Answer:

A pollen tube grows from the pollen grain into the ovary

Explanation:

Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.

<em>However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.</em>

<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>
