One example can be the needle shaped leaves.
In desert areas, there are not much water sources. So basically, any drop of water is precious. To help prevent water loss of plants, for example cactus has very thin leaves that are needle shaped. Or some even don't have any leaves. This can reduce the surface area of leaves and thus reduce the water evaporating to the outer environment.
Another example also shown on cactus is that they have very thick waxy cuticle. It can also prevent water from evaporating from the stem. So that's why you see the stem is very shinny.
You need it in order to be living

The nucleus is basically "the boss" of DNA along with housing it. Hope this helps!
Answer: In Meiosis,chromosomes in a diploid cell resegregate, to give four haploid cells. Genetic diversity takes place during this early step of meiosis. DNA replication takes place before Early Meiosis commence. Pairing of homologous chromosomes which forms synapses is unique to Meiosis.
Explanation: Meiosis is a type of cell division which aides the formation of reproductive materials like the GAMETES SUCH AS SPERM CELLS AND EGGS,During Meiosis cell division takes place which reduces the number of chromosomes in the parent cell by half and produces four daughter cells, Meiosis is essential to guarantee genetic diversity in living organisms.
