They both use a reproductive strategy called alternation of generations, where there are two different reproducing morphologies: a diploid sporophyte, and a haplod gametophyte. The sporophyte produces spores by meiosis (2N -> N), which disperse and form the gametophyte, which produces gametes by mitosis (N ->N). Two of those gametes fuse to create a diplod zygote (N + N -> 2N), which becomes the new sporophyte

There are differences between the two types of plants, especially the relative size of the sporophytes and gametophytes, but they both use this kind of reproductive strategy.

SSSSS [86.1K]

Answer:

1. Apoplastic

2. Symplastic

3. Symplastic

4. Apoplastic

Explanation:

The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.

Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.

jasenka [17]

Answer:

The correct answer is- B) Cell walls are made primarily of peptidoglycan

Explanation:

There is a difference between the cell wall of bacteria, archaea, and eukarya. The cell wall of bacteria is primarily made up of peptidoglycan which contains two sugar N-acetylglucosamine and N-acetylmuramic acid while archaea contain two N-acetyltalosaminuronic acid (NAT) in place of N-acetylmuramic acid which is called pseudo-peptidoglycan.

Eukaryotic cell wall is also different from archaeal and bacterial cell wall and animals in eukaryotes do not have a cell wall. Therefore cell wall made up primarily of peptidoglycan will allow you to classify the organism as belonging to Bacteria but not Archaea or Eukarya.

telo118 [61]

Answer:

Trisomy X, also known as triple X syndrome and 47,XXX, is characterized by the presence of an extra X chromosome in each cell of a female. Those affected are often taller than average.

Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby.
